What is CNC Machining Center?

CNC machining center, also known as gong and drum computer, is a kind of CNC machine tool. It is controlled by a CNC system. The system is developed on the basis of a CNC milling machine. It can process multiple processes such as clamping, drilling, reaming, drilling, tapping, and milling at one time, which greatly improves production efficiency.

Today, YIJIN Hardware would like to share you with a complete guide to the CNC Machining Center, CNC Machining Methods, CNC Machining Process, and the specific Steps of CNC machining.

Classification of CNC Machining Centers

According to the machining center of the spindle in the spatial direction, it can be divided into a vertical machining center and a horizontal machining center.

What Can A Vertical Machining Center Do?

The vertical machining center refers to the vertical state of the main shaft, the structure is simple, the space is small, the price is relatively low, and it is widely used. A vertical machining center is mainly suitable for processing disc and plate parts. Due to the limitation of column height and tool changer, it is difficult to process.

What Can A Horizontal Machining Center Do?

A horizontal machining center means that the spindle axis is in a horizontal state. Compared with the vertical machining center, the horizontal machining center has a complex structure, occupies a large space, and is expensive. It is suitable for the processing of box parts.

Machining of Typical Parts in CNC Machining Centers

Box Parts

Shell parts generally refer to parts with multiple holes, internal cavity, length, width, and height. There are many such parts in machine tools, automobiles, aircraft, and other industries, such as automobile cylinder blocks, gearboxes, lathe boxes, axle boxes, diesel engine cylinders, pump casings, etc.

Box parts generally require multi-station processing of holes, shapes, and surfaces. The wear resistance requirements, especially the geometric tolerance requirements, are relatively strict. Usually, they are processed by milling, hammering, drilling, expanding, reaming, planing, and tapping.

Parts in CNC machining center

The number of tools is large, which requires multiple clamping, alignment, and measurement times on ordinary machine tools, resulting in a complex process, long processing cycles, high costs, and difficulty to guarantee accuracy.

This kind of part is processed in the machining center, and one clamping can complete 60~95% of the process content of the ordinary machine tool. The accuracy of each part is consistent and the quality is stable. At the same time, it can shorten the production cycle and reduce production costs.

CNC machining parts

In the processing station is more, the table needs several rotation Angle to complete the parts, usually choose the horizontal CNC machining center, when the processing station is less, and the spacing is not large, can choose the vertical CNC machining center, processing from one end.

Complex Surface

As for the possibility of machining, if there is no overcut or machining blind area, the ball-end milling cutter can usually be used for three-coordinate linkage machining. If the workpiece has an overcut or machining blind area, such as an integral impeller, the machining accuracy is high and the efficiency is high. Low; consider using a four-coordinate or five-coordinate linkage machine.

CNC turning milling parts

Because complex surfaces generally through rough milling, semi-finishing milling, root cleaning, and other processes, so only a small number of cutting tools, can not give full play to the advantages of automatic tool change machining center, especially the mold type of processing, usually need rough milling, fine milling, root cleaning method.

Molding

Forming parts are irregular shape parts, most of the bracket, base, template, back mold, bracket, and so on point, line, surface mixed processing.

Parts in CNC machinig center

The rigidity of forming parts is poor, the clamping and cutting deformation is difficult to control, and the machining accuracy is difficult to guarantee. At this time can give full play to the characteristics of processing center working procedure concentration, take reasonable technological measures, one or two clampings, and complete multiple or all processing content.

Experience shows that the more complex the machining shape is, the higher the precision is required, and the machining center is used to show its advantages.

Disc, Sleeve, Plate

Disc sleeve or shaft parts with keyway or radial hole or end face with distribution hole system, such as flange shaft sleeve, shaft parts with keyway or square head, etc. Plate parts with more processing, such as all kinds of motor covers.

End face distribution hole system, disc, sleeve, plate, and other parts should choose vertical CNC machining center, with diameter hole can choose horizontal CNC machining center.

CNC Processing Technology

Aluminum Profile Cutting

Aluminum profile cutting is the most basic and common processing method in CNC processing of aluminum profiles. Since the standard size of industrial aluminum profiles is 6020mm, only aluminum profiles of different lengths or angles can be assembled into the frame.

Punching

Industrial aluminum profiles have a variety of connection methods, which need to be punched according to different connection methods. Common punching methods include through holes and stepped holes.

Aluminum Profile Cutting Parts

Through Hole: Used to fasten common bolts (semicircle head).

Step Hole: Mainly used for special connectors (built-in connectors. Fastening connection of internal connector is a common and high technology process in CNC processing of aluminum profiles.

Aluminum Tapping

Aluminum tapping is what we often call tapping wire. The processing of the aluminum profile is according to the technical requirements of the design drawings on the end of the aluminum profile tapping hole thread tapping processing, used for fastening the late frame connection.

CNC turning parts

CNC Milling Machine

The traditional frame assembly of aluminum profiles does not require CNC milling, but in special cases, non-standard parts are used in conjunction with the profiles, and the aluminum profiles are CNC machined according to technical needs.

6 Common Processing Methods

1. Turning

Rotation is mainly to rotate the workpiece and use the tool to cut the workpiece into the desired shape. The inner and outer cylindrical surfaces move on parallel rotation axes to obtain the tool.

The formation of the conical surface is when the tool moves in the oblique direction of the axial direction. The rotating surface is a profiling lathe or CNC lathe, which is fed by the control tool along a curve. Another kind of production of the rotating surface is to use a molded turning tool with lateral feed. In addition, machining thread surface, end face, eccentric shaft, etc. can also be turned.

2. Milling

Milling mainly relies on rotating tools. Milling is divided into horizontal milling and vertical milling. The plane of horizontal milling is composed of the cutting edge on the outer surface of the milling cutter. End milling is formed by the end face edge of the milling cutter. To obtain a higher cutting speed and better productivity, the rotational speed of the milling cutter can be increased. However, the cutting in, cutting, and impact formation of the cutter teeth of the milling cutter are prone to vibration during the cutting process, thus limiting the improvement of the quality of the machined surface.

3. Planing

Planing is a process in which the tool moves the workpiece in a reciprocating straight line. As a result, planning is slower and productivity is reduced. But compared with milling, the accuracy and surface roughness of planing are more stable.

4. Grinding

Grinding processing mainly relies on a grinding wheel and tools to process workpiece, and relies on grinding wheel rotation. In the grinding process, the grinding wheel is mainly the abrasive particles on the grinding wheel to cut the workpiece surface. The grinding itself is also sharpened and gradually blunted, resulting in a decrease in cutting performance and an increase in cutting force.

5. Tooth Surface Machining

Tooth surface processing is a new type of processing method, which can be divided into two categories: one is the forming method, and the other is the expansion method. The forming method is mainly processed by an ordinary milling machine, and the tool adopts a forming milling cutter, which requires two simple forming movements of the tool’s rotary motion and linear motion. However, the machine tools that generally process the tooth surface by the unfolding method are gear hobbing machines, gear shaping machines, etc.

6. Complex Surface Treatment

For dealing with complex surfaces, CNC machine tools can be used. The cutting of the three-dimensional surface mainly adopts copy milling, CNC milling or special processing methods. The imitation milling machine must use prototypes. The profiling head of the ball head is machined with a certain pressure to keep the surface of the prototype in contact. The movement of the profiling head is converted into inductance, and the processing enlargement controls the movement of the three axes of the milling machine and forms the movement trajectory of the tool along the curved surface. Milling cutters usually use milling cutters with radii such as ball and profile heads. The emergence of CNC provides a more effective means for surface machining.

Whenever you are faced with a broken screw tap, the first step is to determine the best way to remove it. There are a few ways to do this, and each method has its own advantages and disadvantages. In this blog post, we will discuss the different methods for removing a broken screw tap and provide some tips on how to make the process go more smoothly. Stay tuned!

What Are Screw Taps?

Screw taps are a type of tool that is used to create threads in a hole. They are usually made of high-quality steel and can be very expensive. Screw taps come in a variety of different sizes and styles, and they can be used on a variety of different materials.

What are taps

How Are Screw Taps Used?

Taps are usually used in conjunction with a die. The die is placed over the tap and turned in the same direction as the screw tap. This cuts the thread into the material.

What Are Some Common Uses for Screw Taps?

Screw taps are commonly used in manufacturing and engineering applications. They can be used to create threads in holes that will be used to hold bolts or screws. Taps can also be used to create threads on the outside of a piece of material, such as a pipe. This is known as “tapping.”

What Are Some Common Uses for Taps?

How Can I Remove A Broken Screw Tap?

There are a few different methods that can be used to remove a broken screw tap. The best method will depend on the type of material the screw tap is made of and the size of the screw tap. Some common methods include using a drill, an EDM machine, a Dremel tool, or a chemical solution. Heat can also be used, but it should be done carefully to avoid damaging the surrounding material.

How Can I Remove A Broken Tap?

17 Practical Methods to Remove Broken Screw Taps

  1. Use a Die Grinder

If you have access to a die grinder, you can use it to remove the broken screw tap. First, you will need to use a drill bit to create a pilot hole in the center of the tap. Next, attach the die grinder to the pilot hole and start grinding away at the tap. You may need to go back and forth a few times before the tap breaks free. Be sure to wear eye protection while doing this, as small metal shavings will be flying everywhere.

  1. Use an Oxy-Acetylene Torch

If you have an oxy-acetylene torch, you can heat up the broken screw tap and then break it free. First, you will need to attach the torch to a tank of oxygen and acetylene. Next, turn on the gas and adjust the flame so that it is about four inches long. Then, place the tip of the flame on the center of the broken tap and start heating it up. After a minute or so, the tap should start to expand from the heat and then break free. Be sure to wear proper protective gear to avoid any injury.

  1. Use a Hammer and Chisel

If you don’t have access to a die grinder or an oxy-acetylene torch, then you can use a hammer and chisel to remove the broken tap. First, you will need to place the chisel on the center of the broken tap. Next, take a hammer and start hitting the chisel. You may need to go back and forth a few times before the tap breaks free.

  1. Use a Drill

If you have a drill, then you can use it to remove the broken tap. First, you will need to find a drill bit that is slightly smaller than the diameter of the tap. Next, attach the drill bit to the drill and start drilling into the center of the tap. You may need to go back and forth a few times before the tap breaks free.

  1. Use a Tap Extractor

Tap extractors are designed specifically for this purpose, making the job much easier. To use a tap extractor, first find the size that matches your tap. Then, insert the extractor into the hole in the center of the tap and turn it clockwise until it’s tight. Next, use a wrench to turn the extractor counterclockwise, and it should start to remove the tap.

  1. Use a Hammer and Chisel

In this method, you will need to use a hammer and a chisel to create a groove around the circumference of the tap. Once again, start by drilling into the center of the tap. Then, use the chisel to create a groove that is about 1/4″ deep. Next, use the hammer to tap on the chisel and work your way around the circumference of the tap. Finally, twist the tap out with a pair of pliers.

  1. Use an Easy Out Tool

Another method is to use an easy-out tool. First, drill a hole into the center of the tap using a drill bit that is slightly smaller than the diameter of the easy-out tool. Next, insert the easy-out tool into the hole and turn it counterclockwise until the tap is removed.

  1. Use A Left-Handed Drill Bit

The eighth method is similar to the above method, except that you will need to use a left-handed drill bit. First, drill a hole into the center of the tap using a left-handed drill bit. Next, insert the easy-out tool into the hole and turn it clockwise until the tap is removed.

  1. Use A Hammer and Screwdriver

Another way to remove a broken tap is to use a hammer and a screwdriver. First, find the end of the tap that is sticking out of the hole. Then, place the point of the screwdriver on the end of the tap and strike it with the hammer. The force of the blow will cause the tap to break, making it easier to remove.

  1. Use A Hydraulic Jack

This method is similar to the above method, except that you will need to use a hydraulic jack. First, find the end of the tap that is sticking out of the hole. Then, place the point of the screwdriver on the end of the tap and strike it with the hammer. The force of the blow will cause the tap to break, making it easier to remove.

  1. Use Lubricating Oil

This is the most common and easiest method. Simply apply some lubricating oil to the threads of the broken tap and try to unscrew it. The oil will help to lubricate the threads and hopefully allow the tap to turn more easily.

  1. Use the EDM Machine

If the above method doesn’t work, you may need to resort to using an EDM machine. This is a specialized machine that uses electrical pulses to break down the metal of the tap so that it can be removed more easily.

  1. Use a Dremel Tool

If you have a Dremel tool, you can use it to grind away at the broken tap until it is small enough to be removed by hand.

  1. Use a Chemical Solution

There are a variety of chemical solutions that can be used to dissolve the metal of a broken tap. These solutions should be used as a last resort, as they can damage the surrounding material.

  1. Use Heat

Applying heat to the broken tap can sometimes expand the metal enough that it will become loose and can be removed by hand. However, this method should only be used as a last resort as it can damage the surrounding material.

  1. Use A Magnet

If the broken tap is made of ferrous metal, you may be able to remove it by using a magnet. Simply place the magnet on the broken tap and wait for it to adhere. Once it is attached, you should be able to pull the broken tap out by hand.

  1. Use Extractor Set

If you have an extractor set, you may be able to remove the broken tap by using one of the specialized extractors. These sets usually come with a variety of different sizes and shapes of extractors, so you should be able to find one that will fit your particular situation.

Why Do Screw Taps Break?

Screw taps break for a variety of reasons. The most common reason is that the screw tap has become worn, and the threads can no longer grip the material it is cutting into. Other causes include damaged taps, incorrect sizes, and improper installation.

The major reasons are explained below:

Poor Quality: The main reason the taps break is poor quality. The taps are made of high-quality steel, but they can still break if they are not properly taken care of.

Wear and Tear: Taps can also break down due to wear and tear. This is especially true if the taps are used frequently. Over time, the threads on the taps can become worn and no longer grip the material correctly.

Damaged Taps: Damaged taps are another common cause of broken taps. The damage can be caused by a number of things, such as incorrect sizes, improper installation, or damage during use.

Incorrect Sizes: If the tap is the wrong size for the hole it is being used in, it can break. This is because the tap will not be able to grip the material correctly and will eventually slip out.

Improper Installation: Improper installation is another common cause of broken taps. If the tap is not installed correctly, it can become damaged and eventually break.

Improper Use: Improper use is another common cause of broken taps. Taps are designed to cut threads into a hole, but they can also be used to cut through other materials. If the tap is used to cut through something it is not meant to, it can become damaged and eventually break.

Lack of Lubrication: Lack of lubrication is another common cause of broken taps. Taps need to be lubricated on a regular basis to prevent them from becoming damaged. Without lubrication, the taps can become dry and brittle, which can eventually lead to them breaking.

Dirty Taps: Dirty taps are another common cause of broken taps. If the taps are not cleaned on a regular basis, they can become clogged with dirt and debris. This can eventually lead to the taps becoming damaged and breaking.

How Can I Prevent My Screw Taps From Breaking?

You can do a few things to help prevent your taps from breaking. First, make sure that you are using the correct size tap for the material you are working with. Second, avoid using damaged taps. Finally, be sure to lubricate and clean your taps on a regular basis properly. This will help to keep them in good condition and less likely to break.

When removing a broken tap, it is important to take care not to damage the surrounding material. A few different methods can be used to remove a broken tap, but some may damage the surrounding material if not used carefully. It is always best to consult with a professional before attempting to remove a broken tap yourself.

The Bottom Line

Taps can break for a variety of reasons, but the most common cause is wear and tear. Screw taps can also break if they are damaged, installed incorrectly, or used improperly. To help prevent your screw taps from breaking, be sure to use the correct size screw tap for the material you are working with and avoid using damaged screw taps. Also, be sure to lubricate and clean your taps on a regular basis. Finally, if you need to remove a broken tap, be sure to consult with a professional before attempting to do so yourself.

Thread Cutting vs Thread Forming – What’s the Difference

2022-05-23T11:07:30+08:00

There are several types of screws, and each has its own benefits and drawbacks.

Some screws, like thread cutting screws, have edges designed to cut their own thread and remove the material as it is inserted. Other screws, like thread forming screws, displace the material instead of removing it as they are pushed into a material.

This blog post will discuss the differences between thread-forming screws and thread-cutting screws. We’ll also talk about when you should use each type of screw.

What Are Thread Cutting Screws

Thread cutting screws are screws with a built-in tap, which allows them to create their own thread as they are driven into a pre-drilled hole. This type of screw is commonly used in applications where a threaded fastener is needed, but it is not possible or practical to tap the threads beforehand. Thread forming screws are available in various sizes and materials to suit a wide range of applications.

Thread Cutting Screws

These screws are typically made from carbon steel or stainless steel, although other materials such as brass or bronze may also be used. The type of metal used will depend on the application and the desired characteristics of the screw. For example, stainless steel thread forming screws are often used in applications where rust resistance is important, such as in outdoor or marine environments.

When selecting screws, it is important to consider the thread size, length, and head style that is appropriate for the application. The thread size will determine the diameter of the screw and the size of the hole that needs to be drilled. The length of the screw will determine how deep it can be driven into the material. The head style will determine how the screw can be driven and removed. Common head styles include Phillips, slotted, and hex.

Thread Cutting Screws

These screws are a versatile type of fastener that can be used in various applications. They are particularly well-suited for use in situations where it is not possible or practical to tap threads beforehand. When selecting form tapping screws, it is important to consider the size, length, and head style that is appropriate for the application.

What are Thread Forming Screws?

Thread forming screws are self-tapping screws that are used to form threads in thin metal sheets. These screws are also known as thread rolling screws or tap forming screws. Thread forming screws have a tapered shank with multiple cutting edges.

The tapered shank allows the screw to cut threads into the metal sheet as it is screwed into place. The cutting edges on the shank of the screw also help to grip the metal sheet, preventing the screw from coming loose over time.

Thread forming screws are available in a variety of sizes and materials. The material used for the screw will depend on the application. For example, stainless steel thread forming screws are often used in food processing applications because they are resistant to corrosion.

Thread Forming Screws

There are many benefits to using thread-forming screws instead of traditional screws or bolts. One benefit is that thread forming screws do not require a pilot hole to be drilled before installation. This saves time and money by eliminating the need for a separate drilling operation. Another benefit is that thread-forming screws create a stronger connection than traditional screws. The threads cut into the metal sheet by the screw help grip and hold the screw in place. This prevents the screw from coming loose over time, which can be a problem with traditional screws.

Thread forming screws are typically used in applications where a strong, permanent connection is required. They are commonly used to fabricate electronics, computers, and appliances. Thread forming screws are also used in automotive applications, such as attaching body panels to a car frame.

Fasteners,screw,rivet,nuts and bolts,bolts,self tapping screws

If you are looking for a strong, permanent connection, thread-forming screws are a great option. They are easy to install and create a stronger connection than traditional screws.

Thread Cutting vs. Thread Forming – Summarising the Difference

Thread Cutting Screws: Used to create a thread in a hole that is already drilled. The screw creates the threads as it is turned, so there is no need for a tap. These screws are used when creating new threads in softer materials like aluminum or plastic. 

Thread Forming Screws: Used to form a thread in existing material. The screw forms the threads as it is turned, so there is no need for a pre-drilled hole. These screws are used when creating new threads in harder materials like steel or brass.

16 Turning Operations You Need To Know

2022-05-17T17:20:06+08:00

What is Turning?

Turning is a machining process in which a cutting tool removes material from the surface of a workpiece. The cutting tool is usually a non-rotating tool bit or cutter. The workpiece is usually rotated on a lathe or turning machine.

Turning can be done manually, using hand tools, or it can be done with machine tools. The most common method for turning is to use a lathe or lathe-like machine. The lathe consists of a bed, headstock, tailstock, and carriage. The workpiece is held in the chuck on the headstock and rotated by the lathe. The cutting tool is mounted on the carriage and moved along the length of the workpiece as it rotates.

What are The Most Common Lathe Operations?

A lathe machine is one of the most versatile machines in a workshop. It can be used for turning, facing, drilling, and other operations.

The three most common lathe operations are turning, facing, and drilling.

  • Turning is the process of shaping a workpiece by rotating it against a cutting tool. The cutting tool removes material from the workpiece to create the desired shape.
  • Facing is the process of creating a flat surface on the end of a workpiece. The cutting tool is fed along the axis of the workpiece to remove material and create a flat surface.
  • Drilling is the process of creating a hole in a workpiece. The cutting tool is fed into the workpiece and rotated to create a hole.

What is Taper Turning?

Taper turning is a machining process used to create tapered surfaces on cylindrical workpieces. The process is typically performed on a lathe and can be used to create both male and female tapers. When creating a male taper, the workpiece is mounted between centers and machined along its length with progressively smaller cuts.

When creating a female taper, the workpiece is again mounted between centers but is machined with progressively larger cuts. Taper turning can be used to create a variety of different shapes, including cones, frustums, and truncated cylinders. The process is frequently used in the manufacturing of shafts, spindles, and other tapered components. In addition to its use in metalworking, taper turning can also be used to create tapered components from wood, plastic, and composite materials.

The Right Lightweight Metal

1. Improved Fuel Efficiency

Improved fuel efficiency is the biggest benefit of using lightweight metal. By reducing the weight of a product, less energy is required to move it. This indicates that less fuel is required to power vehicles and machinery. As a result, fuel costs are reduced and fewer greenhouse gases are emitted.

2. Increased Performance

Increased performance is another benefit of using a lightweight metal. By reducing the weight of a product, less energy is required to move it. This means that products can be moved faster and with more agility. As a result, productivity is increased and turnaround times are reduced.

3. Reduced Emissions

Reduced emissions are another benefit of using a lightweight metal. By reducing the weight of a product, less energy is required to move it. This means that fewer greenhouse gases are emitted into the atmosphere.

4. Improved Safety

Improved safety is another benefit of using a lightweight metal. By reducing the weight of a product, less energy is required to move it. This means that products are less likely to cause injuries if they fall or are dropped.

5. Extended Life Span Of Products

The extended life span of products is another benefit of using a lightweight metal. By reducing the weight of a product, less stress is placed on its components. As a result, products last longer and need to be replaced less often. This reduces waste and helps to save money in the long run.

How To Determine The Best Alloy For Your Project?

1. Know Your Application.

The first step in determining the best alloy for your project is to know the specifics of your application. What will the piece be used for? What environment will it be used in? What are the required properties of the alloy? Answering these questions will help you narrow down the field of alloys to consider.

2. Consider The Properties Of The Alloy.

Once you know the required properties of the alloy, you can begin to narrow down your options by considering the properties of each candidate alloy. For example, if strength is a primary concern, you will want to focus on alloys with high yield strength. If corrosion resistance is a primary concern, you will want to focus on alloys with high corrosion resistance.

The Right Lightweight Metal

3. Consider The Cost Of The Alloy.

Alloys can vary widely in price, so it is important to consider the cost of each candidate alloy when making your decision. In general, higher-performance alloys will cost more than lower-performance alloys. However, it is essential to evaluate the cost of the alloy against the benefits it provides for your specific application.

4. Consider The Availability Of The Alloy.

Not all alloys are available in all locations. When making your decision, be sure to consider the availability of the alloy in your specific location. Alloys that are not widely available may be more expensive and may require special ordering, which can impact the overall cost and timeline for your project.

5. Work With An Experienced Alloy Supplier.

An experienced alloy supplier can be a valuable resource in helping you select the best alloy for your project. They can offer you information about the alloys they offer and can help you compare the alloys against your specific application requirements. In addition, they can provide you with pricing information and can help you understand the availability of the alloys in your specific location.

When it comes to selecting the best alloy for your project, there is no one-size-fits-all solution. The best alloy for your project will depend on several factors, including the specifics of your application, the required properties of the alloy, and the cost and availability of the alloy.

By considering all of these factors, you can make an informed decision about which alloy is best for your project. And by working with an experienced alloy supplier, you can be sure that you are getting the best product for your particular needs.

Conclusion

Aluminum alloys are the best option for lightweight metal parts. They have a high strength-to-weight ratio and can be easily machined into complex shapes.

While other materials may be less expensive, they lack the properties that make aluminum alloys the ideal choice for lightweight components.

If you’re looking for a material that is both strong and light, aluminum alloys should be at the top of your list. Hopefully, you enjoyed this post. Share your thoughts in the comment box below. Also, share this post on social media!

Turning Problems of Stainless Steel

1. Selection of Cutting Tools

Turning stainless steel requires high heat resistance, good wear resistance, and stainless steel affinity to small cutting tool materials. It used high carbon, molybdenum system, and high vanadium high-speed steel. If the tool material has good toughness that can be selected larger rake Angle to reduce the hardened layer depth of cutting force and cutting temperature. At the same time, the blade is sharpened to make the cutting light, and the chip is not easy to bond with the tool.

2. Selection of Cutting Parameter

The cutting speed of turning stainless steel only is 40%-60% of that of turning ordinary carbon steel, if too high will cause the tool to be worn faster. The turning speed should be (50-100)m/min of general hard alloy, and the cutting speed is (10-20)m/min of a high-speed steel turning tool.

3. Selection of Cutting Fluid

In general, it’s better to choose a special stainless steel turning cutting fluid, such as Duomei stainless steel turning cutting fluid for high lubrication or biodegradable water-soluble microemulsion cutting fluid. They have good cooling, lubrication, anti-rust functions, safety, and stability. The ideal processing effect can be obtained using this cutting fluid, such as improving the processing surface finish and processing efficiency, prolonging the service life of the tool, etc.

The Characteristics of  304 Stainless Steel Turning Processing

  1. Cutting Force Is Big

    The hardness is not high of 304 Austenitic stainless steel(the hardness ≤ 187Hbs), because it contains a lot of Cr, Ni, Mn, and other elements, and there is good plasticity(the percentage elongation after fractureδ5≥40%, percentage reduction of area ψ≥60%). It has large plastic deformation in the cutting process, especially at a higher temperature can still maintain a high strength (the strength of ordinary steel decreases significantly when the cutting temperature rises), which will lead to the large cutting force of AISI 304 Austenitic stainless steel. Under conventional cutting conditions, the unit cutting force is up to 2450MPa of AISI 304 stainless steel, more than 25% higher than 45 steel.

  2. Severe Work Hardening

    AISI 304 stainless steel is accompanied by obvious plastic deformation during cutting, the material lattice will produce serious distortion. At the same time, due to the stability of austenite structure defects, a small part of austenite become martensite in this process. In addition, the impurity compounds in the austenite will decompose due to heat during the cutting process, dispersed impurity produces a hardened layer on the surface, making the work hardening phenomenon very obvious. After hardening, the strength is more than 1500MPa of σb, and the depth is 0.1-0.3mm of the hardened layer.

  3. High Local Temperature in the Cutting Area

    Due to the AISI304 stainless steel required big cutting force and the chip is not easy to cut off. As a result, the separation of chips consumes more function. The cutting heat of AISI 304 stainless steel is about 50% higher than that of mild steel under normal conditions. Austenitic stainless steels have poor thermal conductivity, the thermal conductivity is 16.3-21.5W/m·K of AISI304 stainless steel, which is only one-third of the thermal conductivity of 45 steel. Therefore, the temperature of the cutting area is higher (usually the heat taken away by the chips during cutting should account for more than 70% of the cutting heat)A large amount of cutting heat is concentrated in the cutting zone and the “cutter-chip” contact surface and the heat transferred to the tool is up to 20%(this value is only 9% when cutting ordinary carbon steel). Under the same cutting conditions, the cutting temperature of AISI304 stainless steel is about 200-300℃ higher than that of 45 steel. 

  4. Cutting Tools Are Prone to Adhesive Wear

    Due to the high-temperature strength of austenitic stainless steel, so the work hardening tendency is large. Therefore, the cutting load is heavy between the austenitic stainless steel and the tool and the chip will be significantly enhanced because of the affinity trend between the cutting process and the tool, and inevitably produce bonding, diffusion, and other phenomena, and generate “chip tumor”, resulting in tool adhesion wear. In particular, the hard inclusion formed by a small part of carbide accelerates the tool wear and even causes blade collapse, which greatly reduces the service life of the tool and also affects the surface quality of the processed parts.

The number of tools: 5 tools

Tool type: 2mm center drill, 2mm alloy drill bit, 45°round turning tool, 55°male screw-cutting tool, 2mm cut-off tool

4. Milling machining thickness of 5.4mm.

5. ∅2mmthrough hole machining.

6. Cutting total length to 131.9mm.

7. ∅4mm hatching knurling. Because the threaded rod is too long and fine, directly knurling will cause parts to be a deflection, deformation, uneven knurling, and other phenomena, so we chose special knurling equipment to process.

In fact, YIJIN Hardware has enough capacity to process copper, aluminum alloy, stainless steel, iron, and other materials. Today what we show are the precision copper parts processed by YIJIN Hardware’s four-axis CNC machining center.

Attention Points of Precision Copper Parts Processing

According to the characteristics of copper itself, the first thing to consider in the process of processing is the ductility of copper. We all know that the better the ductility of the workpiece, the softer it is. For soft copper parts, it is difficult to process lathes, which requires CNC lathe processing of copper parts. There are two points that are very important when processing copper parts, the first is the feed rate during cutting, and the second is the feed amount during cutting. This is the copper parts CNC lathe machining process especially pointed out two key factors.

precision copper parts machining

A very important factor of copper is that its hardness is relatively low, which is very prone to problems during processing. Copper is soft, chips are easy to bond on the blade, affecting the quality of the processed surface and the durability of the tool, and the surface of the machined part is easy to produce water ripple waveform, and will emit noise. The expansion coefficient of pure copper is large, and it is easy to deform under the influence of cutting temperature, and it is not easy to control the finishing size and geometric accuracy. If pure copper contains free-cutting elements such as sulfur and zinc, it will change its machinability. The toughness and plasticity of copper are relatively large, and the thermal deformation during cutting is also large, so the tool is required to be sharp to achieve the purpose of light cutting and smooth chip removal, and to reduce the cutting temperature as much as possible.

When using a CNC vertical machining center for high-speed milling of copper parts, with the increase of cutting speed, the cutting force should be reduced accordingly, which can greatly reduce the deformation coefficient of copper machining parts. The surface quality of high-speed milling copper alloy is very good, which can save subsequent finishing; When cutting copper parts, the surface quality increases with the increase of the cutting speed and decreases with the increase of the feed speed, but in high-speed machining, increasing the feed speed has a much smaller impact on the surface quality than at low speeds.

DMG 4-Axis CNC Machining Center

This time, the precision copper parts are processed by the Demag four-axis CNC machining center. The processing table is 850 mm, the processing stroke is X/Y/Z=850/550/550, and the processing accuracy can reach ±0.01 mm. After the machined part is clamped, it can complete the process of turning, tapping, milling, boring, reaming, and other processes, especially in drilling and tapping, it has a very special speed and affects performance. Suitable for machining various precision parts.
