CNC Turning Parts, Milling Parts, Aluminum Parts Introduction

The Characteristics of CNC Turning Parts

The production of CNC turning parts is by using related tools on a lathe to carry out the cutting and grinding of industrial parts. It is a basic and common cutting method with a wide range of applications including the machining of the inner and outer surfaces of a cylinder of a cone.

Because of the faster and faster development of modern CNC machining parts technologies, various engineering materials with high strength and high hardness have wider and wider applications. Traditional cutting technologies are not enough anymore. The appearance of modern CNC turning makes it possible to meet such new requirements and the modern CNC turning has been proven to be obviously rewarding and effective during production. It has a lot of characteristics of the CNC machining process. The following is a brief introduction.

A Brief Introduction to the Characteristics of the CNC Turning

(1) The CNC turning parts have higher working efficiency.

Turning has higher efficiency with a higher cutting speed. During CNC machining, multiple surfaces can be treated by CNC turning once, but grinding needs multiple times installation. Therefore, it has a shorter CNC machining time and higher machining precision.

(2) The investment in equipment, as well as the cost of the auxiliary system, is low. Compared with large batch machining and production, turning does not need any special equipment for small batch production, so a lot of expenses can be saved to some extent. It has a higher cost performance.

(3) CNC turning allows the CNC machined parts to have more significant overall machining precision and effect.

During CNC turning, a large proportion of heat can be dissipated to reduce the temperature, while burns and cracks occur on the surface during grinding. This machining effect of high quality and durability guarantees high precision at the engagement cnc precision machining part between surfaces.

Cutter Materials for CNC Turning and How to Select

(1) Alloy cutter with coating

The alloy cutter with hard coating usually has the following two functions: It has relatively very low heat conduction, reducing the heat from the cutter. It is able to effectively control the harmful effects due to friction and adhesion that appear in the process and also reduce the generation of cutting heat to some extent.

(2) Ceramic cutter

The ceramic cutter has very high hardness and strength. It demonstrates high durability and high speed during normal operation for production, especially applicable to the precision cnc machining of materials with high hardness.

The Selection of Cutting Oil and How to Use

(1) The steel cutter of a tool type does not have good heat resistance and loses certain hardness at high temperatures, so the cutting oil with good cooling as well as low viscosity and low fluidity is required.

(2) A hard alloy cutter has a high melting point and high hardness with excellent chemical stability and thermal stability, so the cutting oil with a certain activity can also be used during ordinary machining. If the cutting degree and the cutting temperature are both high, the cutter tends to wear easily. This is where you should select cutting oil without activity and increase its flow to ensure sufficient cooling and lubricating effects.

Do not ever underestimate the machining technologies and procedures for CNC turning parts. There are a lot of merits worth our attention during this kind of machining. Among others, lots of useful skills also allow us to be more familiar with, understand, and even master the machining of CNC turning parts, so that more accurate and efficient utilization can be achieved.

What Parts Does a CNC Milling Parts Manufacturer Produce?

Generally, a CNC milling parts manufacturer produces two types of parts: flat surface parts and curved surface parts. The parts for milling are usually rough machining parts because this is the initial stage of machining. However, CNC milling is actually in the machining model of full automation. So during CNC milling, what operation standards need to be followed for machining parts and what should we pay attention to?

Traditional milling is conducted manually by the technicians who need to learn milling lathe technologies, while CNC milling is one of the CNC technologies involving CNC programming. Therefore, the operation standards for the process of CNC milling are about focusing on the technologies of CNC programming without mistakes or disorder. The parts by CNC milling are actually instruments with high precision, so such a CNC milling cutter is not cheap. Sometimes even a tiny program mistake can lead to the loss of the cutter, so the CNC program for CNC milling must be mistake-free, or an accident could occur and the CNC instrument is damaged.

When CNC milling is operated for custom cnc machining parts, it is better to avoid any mistakes in programming, and there are other aspects needing attention such as the operation standards. For example, when an irregular custom cnc machining part is machined, it is better to try to place it in the central position for even stress during CNC milling, because the cutter works on its surfaces. Otherwise, an accident could occur because of instrument damage due to uneven stress.

The technicians in an ordinary CNC milling parts manufacturer have been well-trained professionals, with no problem following operation standards. There is a lot to pay attention to about the operation standards. Although CNC milling is a technical precision cnc machining process, a series of inspections must be carried out during CNC milling, covering the appearance of the CNC machine. CNC milling itself follows a curtain rail to mill parts based on the program, so the milling rail and the cylinder unit in the machine need to be checked for oil leakage before milling. Oil leakage would lead to the situation of milling until loosening.  Besides, there must be scrap iron due to custom machined parts machining during milling, so the scrap iron needs to be well clear before milling.

In addition to operation standards, a CNC milling parts manufacturer generally has certain requirements for the cutter used to cnc turning machine parts. The cutter used to machine flat surface CNC parts is different from that used to machine curved surface parts. Usually, a vertical milling cutter is used to machine flat surface CNC parts with certain requirements of the cutter body material. Different materials to be machined require different cutter body materials. A hard alloy blade is used to machine common flat surface CNC parts. A ball head cutter is used for the machining of curved surface parts.  However, as far as use efficiency is concerned, the cutter for flat surface CNC machining is usually better than that for curve surface machining. Therefore, the former is preferred. CNC technologies can also be used to machine irregular workpieces, for which a combination of various cutters is preferred.

How Does a CNC Machining Parts Manufacturer Produce Parts? Hot to Utilize CNC Technologies

CNC machining is a set of completed technologies because digital technologies are used for CNC machining parts in the whole process and the machine is completely controlled by digital programming to work on some parts. CNC machining technologies can avoid a lot of disadvantages of manual part machining. Besides, parts are machined by a digital lathe in the whole process, with higher precision and shorter time consumption. So how do a CNC machining parts manufacturer manufacture parts? How to use CNC technologies for part machining?

Using CNC technologies for CNC part machining is both easy and difficult, depending on CNC part programming for machine tool control. How a machine tool controls the CNC cutter for part cutting requires simple programming for the machine tool, and you can use this program to rapidly control the machine tool to manufacture a lot of uniform parts with high precision. What is the process of custom cnc machining parts with a CNC machine tool?

CNC Machining process

A CNC machining parts manufacturer has a scheme for CNC machining. To learn how to use a CNC machine tool for programmed CNC machining, first of all, understand its operating principle. The operating principle of a CNC machine tool is like cutting a complete object by using a point in a 3D space. This object is the part that you need, and the machine tool’s cuter is the point. The CNC cutter cuts the whole precision cnc machining part unlimitedly until it becomes what you need. The 3D space where the point is positioned needs to have several coordinate axes, x, y, and z, which are used for simple programming.  Controlled by the program, the CNC cutter moves along the programmed route. It is easy to understand this CNC programming. It is kind of like the three-view diagram that you have learned at school, but to image this three-view diagram into a space diagram, the digital program needs to be more complicated. Connection points of the coordinate view need to be marked specifically on the three coordinate axes. Start the machine tool. When the machine tool starts to operate, the CNC cutters in the machine tool cooperate to machine the original workpiece until manufacturing the part that you need. The technical principle of CNC machining parts is generally the above.

A lot of actual practice is also required for CNC technologies, and there are certain requirements to operate the CNC machine tool. Wrong programming will lead to damage to the CNC cutter.  Hence, when operating a machine tool, you must be familiar with its programming mode and follow the operation standards, so as to avoid damage to the machine tool due to nonstandard operations. Besides, during digital programming, a CNC cutter is very important for the CNC machine tool, because CNC technologies are about using the machine tool to control the CNC cutter for machining. In order not to damage the CNC cutter, try to avoid misoperations that are harmful to the machine tool.

A CNC machining parts manufacturer has high requirements for CNC machine tools. Machine tool programming is used by CNC machining to manufacture parts, so using a good machine tool can manufacture a lot of corresponding parts. The CNC machine tool has a wide range of applications. A lot of industrial parts are manufactured by the use of CNC machine tools, and currently, the CNC machine tools can be divided into two types: the one with manual CNC programming and the one with automatic CNC programming.

What is Siemens and what is Fanuc?

Siemens and Fanuc are two companies engaged in industrial automatic production technologies. They have the same businesses and also different businesses. They are different in many aspects, but they are both famous around the world as CNC technology suppliers. Siemens is a German company, while Fanuc is a Japanese company. Although they are both CNC technology suppliers, they have different technologies essentially.


Established in October 1847, Siemens is a company with a long history. Siemens started its business in China as early as 1872. Siemens has business in various fields such as industry, energy, infrastructure, medicine, and household appliance, and its CNC technologies including the CNC system are world-leading. For example, Siemens uses a structured design of modules for openness, which can meet the requirements of various machine tools with multiple processes.

Fanuc is a Sino-foreign joint venture established in December 1992, more than 100 years later than Siemens. Dedicated only to industrial projects in the field of CNC machine tools, Fanuc has industrial technologies on the level of leading modern CNC.

If you compare Siemens with Fanuc, it is about the comparison between the same CNC technologies from both of them. Siemens has high technical requirements and focuses on openness, with technologies meeting various machine tools, while Fanuc features durability. It is not exaggerated to say that Fanuc has the most complete lathe system, grinding machine system, and milling system, basically covering all machining center systems. Fanuc has a lot of advantages, one of which is the representative durability that is unparalleled.


Whether you like Siemens’ system or Fanuc’s system depends on your preference for the CNC system. Durability or openness? The inertia of a machine tool is also a factor. Generally, the inertia of a machine tool from Germany is larger than that of a machine tool from Japan, and that is why Siemens’ products are less durable and rougher, but its technologies are excellent. The inertia of Funac’s machine tool is smaller,   so its manufacturing is finer.

The CNC machine tools of the two brands Siemens and Fanuc has their own advantage and disadvantages. It is just like the comparison between cars from Germany and Japan which have their own features. As far as the price is concerned, the Fanuc machine tool costs less than the Siemens machine tool. Actually, the comparability between them is not quite fair, because every machine tool has its own cost performance. The machine tool with a higher price naturally has better performances, but nobody can guarantee that a good machine tool has no disadvantages, just like cars.

What Needs to Pay Attention for CNC Aluminum Parts?

Actually, during industrial production and manufacturing, aluminum parts are often machined, and generally, CNC aluminum parts are the most common. However, because of metal particularity, aluminum products are softer than steel or iron products, to make CNC machining technologies more stable, certain precision requirements are needed for the machining process of CNC aluminum parts. Especially, in order for the CNC aluminum parts to be safer and more stable, the CNC machine tool has very high precision requirements.

CNC Aluminum Parts manufactured by YIJIN Hardware

First of all, the CNC machining aluminum part needs to be considered from different angles. For example, there are requirements for the CNC machine tool of CNC aluminum parts, there is a clear division in terms of machining fineness for CNC machine tools, and attention needs to be paid to the precision requirements for CNC programming variables during the programming of the CNC aluminum parts. After all, during the production of CNC aluminum parts, the CNC technologies for mass production are usually used. Therefore, the current variables for CNC technologies must be precisely determined. When a CNC machine tool is powered on, be sure to check the variables of the CNC machine for changes. A CNC machine tool has a memory program that is checked for changes every time the CNC machine tool is powered on as well as a test before the CNC machine starts up. There are inspections required for CNC aluminum parts before or during machining.

During CNC aluminum parts machining, a clear division is needed to determine the basic model and specific parameters of the aluminum part for CNC machining, and then stratified CNC aluminum parts technologies are required. So what are stratified CNC aluminum parts technologies? The CNC machining of aluminum parts can be divided into rough machining and fine machining. During CNC machining, the principle of rough machining first and then fine machining is preferred. For this process, besides the principle of rough machining first and then fine machining, the principle of surface machining first and then hole machining needs to be followed.  For some aluminum parts, to guarantee their precision without wasting materials, try to use splicing instead of welding.

There are also certain requirements for the basic parameters of CNC aluminum parts. Generally, precision is required for the cutter materials, CNC angle variables, and some numbers of rotations as well as some flat surface cutting variables used for CNC aluminum parts. Special blades dedicated to aluminum alloy cutting are usually selected as CNC variable cutters. Be sure not to use the wrong cutter just to save trouble, because different materials require different cutters.  The requirement of the number of rotations is determined based on the size and shape of the CNC aluminum part. For an outer circle not too big, it is about 1,000, the cutting amount is about 0.8 and the feeding amount is between 3 – 4 mm.

There is another thing needing special attention. The raw metal material for machining CNC aluminum parts is soft, so you must be very careful during clamping. Because the machining process for aluminum parts is not easy, be sure not to damage aluminum parts during machining so as to avoid more loss.

What are the Advantages of Manufacturing Parts by CNC in China?

The current situation of China’s development shows that actually, most industries in China are about CNC manufacturing. China is now in an era of high-speed development, and a lot of common parts in life are manufactured precision machined components by CNC in China, which is also a trend. For example, some automobile parts, industrial parts, and parts used for production are all CNC machining parts from China. As you can see, CNC technologies are so critical to life and industrial business development.

Why are the CNC machining parts from China so welcomed on the market? Where are the advantages of CNC machining parts reflected? Compared to the traditional parts machining industry, the current CNC technologies require much less manpower. In the traditional lathe industry, one worker is required to operate each machine tool for CNC machining parts, and the CNC machining precision is not very high. The machining precision of some precision cnc machining parts used for precision instruments is very low. In CNC machining, you only need to enter the required value into the programmed machine tool to directly machine parts. Only one worker is required to watch several machine tools, so the labor cost can be saved a lot.

Besides, manufacturing parts by CNC in China saves not only labor costs but also time costs, because a manual lathe is operated by people while mechanization is achieved in the whole machining process of parts on a CNC machine tool. Mechanized machining is much faster than manual machining. In an era when everybody stresses high efficiency, CNC machining can actually save a lot of time cost. In mass production of parts, the CNC machining technologies not only lead to high precision but also save labor costs, and take much less time than manual production. These are all the advantages of CNC machining.

The CNC machining technologies for parts can also help to save a lot of technician training costs, and a CNC machine tool can be used for both fine machining and rough machining. There are a lot of departmental subdividing in the traditional machining industry, but modern CNC technologies only need the technicians to conduct programming for the parts to be machined. Combined CNC machining can be carried out for parts, including a combination of milling and turning and a combination of milling and cutting. Compared to single function dividing in the traditional industry, the CNC technologies have a much better combination.    Therefore, the CNC machining technologies for parts are much better than the traditional machining technologies.

Because CNC machining parts in China have a lot of technical advantages, nowadays CNC machining technologies for parts are popular to some extent. Speaking whether, from the industrial angle or the accuracy, efficiency, and convenience required for manufacturing, the CNC machining technologies for parts have advantages.  Especially the CNC machining technologies for parts have dealt with the problems of complexity, quantity, variability, and accuracy in a good way. Therefore, of all the parts manufactured mechanically, most are actually achieved by CNC machining, which gives you a glimpse of its advantages.
