Applications of CNC Machining Services
CNC machining technology is mainly a technology adopted under digital information, with the characteristics of digitalization and automation. CNC machining technology has the characteristics of automation, which can realize the automatic control of mechanical equipment in mold production, and it is also widely used in many aspects.
CNC machining technology involves two applications, namely CNC machine tool machining technology and CNC programming technology. These two technologies cooperate with each other in the mold manufacturing process and play their respective roles. CNC machine tools are the hardware foundation of CNC machining, which can improve the efficiency and precision of mold production. CNC programming is an important link to realize CNC machining.
In the processing and production of molds, in order to achieve the quality of parts processing more effectively and maximize the performance of CNC machine tools, people have been pursuing the rapid and efficient development of CNC processing technology. In the production process of mold manufacturing, in order to adapt to the diversified production of molds, CNC machining technology should develop in the following three directions:
1. Choose the right CNC machine tool
There are many types of CNC machine tools, and many CNC machine tools are used in mold manufacturing. For example, CNC EDM, CNC wire EDM, CNC milling, etc. These CNC machine tools are often used in the production of molds.
Before mold processing, it is necessary to reasonably classify the molds to be processed, and then select the appropriate CNC machine tool for processing, in order to reduce the production cost according to the production requirements and achieve the most effective production.
2. Improve CNC machining technology
With the increasingly fierce competition in the market today, the mold manufacturing industry has also developed in this fierce competitive environment, and the development of CNC processing technology must continue to meet the needs of mold development. Therefore, CNC machining technology must be continuously improved, and enterprises must increase investment in the research and development of CNC machining technology, and constantly adopt new materials. It is necessary to use materials with good economic effects to ensure that the manufacturing quality of mold products is improved. At the same time, it can also accelerate the speed of mold production. While choosing good materials, CNC machining technology should also be continuously improved.
With the continuous innovation of technology and the continuous development of CNC machining technology, many problems in mold production have been solved. For example, for the manufacturing and production of more complex curved surface molds, a combination of CNC milling and CNC wire cutting can be used to ensure the smooth completion of mold processing.
3. Optimize processing procedures
CNC programming is an important link to realize CNC machining. CNC programming technology is a manifestation of the level of CNC machining technology. In the processing and production of molds, in order to improve the quality of parts processing, it is necessary to maximize the performance of CNC machine tools.
Programming technology is mainly related to three factors, namely the quality of processing, the time and the content of the program. In the manufacture of molds, programming technology is used to reduce the time in the processing process, and high-speed production can be achieved.
The importance of CNC machining system in the manufacturing process of auto parts
With the rapid development of the automobile industry, the efficient, high-precision, and high-stability processing of complex key parts of automobiles has become an effective measure to shorten the production cycle of products and improve the efficiency and competitiveness of enterprises. CNC machining services can easily realize rapid prototyping and manufacturing of complex auto parts. At the same time, virtual manufacturing technology, flexible manufacturing technology, and integrated manufacturing technology in CNC technology have been widely used in modern automotive processing and manufacturing. Compared with manual manufacturing, CNC technology lays the foundation for realizing the standardization and standardization of auto parts manufacturing, and improving the production quality and actual equipment rate of domestic auto parts. CNC machining services can provide a complete set of automation solutions for the manufacturing of key automotive parts. The machining data is received based on the industrial Internet and big data monitoring of the machining process and remote services, followed by virtual machining and program code inspection, and then the use of CNC system The functions of self-sensing, self-learning, self-adaptation, and self-optimization of the processing state realize the high-quality processing of the workpiece, and then use the online batch inspection method of industrial robots and CNC machine tools to realize the efficient and flexible processing and batch production of CNC machine tools in automotive key components Widely used in manufacturing.
Types of CNC machining systems commonly used in the manufacturing process of auto parts
At present, domestic CNC machine tools and imported machine tools from Japan, the United States and Europe mostly use FANUC (FANUC) and Siemens (SIEMENS) two numerical control systems, both of which can be programmed by G code. Among them, most CNC turning and CNC multi-axis milling CNC machine tools adopt the above two numerical control systems, and are easy to integrate with computer-aided design. The above twonumerical control systems occupy the vast majority of market shares in today’s machine tool CNC machining service industry. Nowadays, some German multi-axis machining centers for complex surface processing are equipped with HEIDENHAIN CNC system, which has visualization and modular large-scale program editing capabilities, which can quickly insert and edit information and realize complex surface and Rapid prototyping of porous structures. With the continuous development and establishment of smart manufacturing and smart factories, some machine tool companies have begun to develop special numerical control systems in accordance with customer requirements, such as OKUMA, YAMAZAKI MAZAK, and DMG Senjing Machine (DMG MORI) Company, China Shenyang Machine Tool (SMTCL) Company, etc.
Prospects for the development trend of CNC services in the future
Facing the demand for high-quality and high-efficiency integrated intelligent production and manufacturing of complex parts with multiple degrees of freedom, the future CNC machining service will develop in the direction of multi-degree-of-freedom composite processing, realizing the completion of turning and milling of multiple processing surfaces at one time. Multi-process compound processing such as, drilling, etc. In addition, the CNC machining system needs to have more advanced trajectory planning strategies and motor control strategies to achieve high-speed and high-precision machining. With the development trend of intelligent manufacturing, CNC machining system needs to have a highly intelligent human-machine interface, and realize the processing technology planning function and the diagnosis and adaptive control strategy of the processing process. The future CNC machining system will realize the machine tool Self-monitoring and management throughout the entire manufacturing process. The CNC machining system can automatically plan the installation position, machining track and machining tool according to the 3D model of the parts. It is more likely to use Ethernet and Internet technology to realize the communication and cooperation between the machine tools in the factory, and the planning time is the shortest process step. The communication with the manipulator realizes automatic loading and unloading, card loading and handling, etc., and realizes the automatic intelligent rapid prototyping manufacturing of key complex parts.
The good flexibility of CNC lathe processing. High adjustment and high processing accuracy have long been concerned by automakers. With the intensification of market competition; multi-variety production meets the diversified needs of the market to the greatest extent, until it meets every CNC lathe processing The needs of users have become the goal pursued by manufacturers in the automobile manufacturing industry, and flexible manufacturing units with CNC machine tools as the main body are widely used. Nowadays, there are two key development directions of CNC machine tools: CNC high-speed CNC lathe processing, to achieve high efficiency at high speed; speed up the development process of automation.
CNC machining has a very high position in CNC equipment. Many parts processing companies will apply CNC machining centers. So what types of parts can be processed by CNC CNC machining services?
As we all know, CNC machining centers are suitable for machining parts that are complex, have many procedures, are demanding, require multiple types of ordinary machine tools and many tool fixtures, and can only be processed after multiple clamping and adjustments.
CNC box parts machining service
Generally, it refers to a part that has more than one hole system, a cavity inside, and a certain proportion of length, width, and height. Parts such as CNC machining centers are used more in machine tool, automobile, aircraft manufacturing and other industries. Box parts generally require multi-station hole system and plane processing, with higher tolerance requirements, especially the stricter form and position tolerance requirements, usually through milling, drilling, expanding, boring, reaming, countersinking, tapping and other processes , Need more tools. To
CNC machining service for special-shaped parts
Special-shaped parts are parts with irregular shapes, and most of them require multi-station mixed processing of points, lines and surfaces. The rigidity of special-shaped parts is generally poor, the clamping deformation is difficult to control, and the machining accuracy is difficult to guarantee, even some parts of some parts are difficult to complete with ordinary machine tools. When processing with CNC machining center, reasonable process measures should be adopted, one or two clamping, and the characteristics of multi-station point, line and surface mixed processing of the machining center should be used to complete multiple processes or all process content. These parts are used in life products such as SLR cameras, harmonicas, golf clubs, heat sinks, bicycles, remote control racing cars, watches, handles and other consumer products.
CNC special parts machining service
With certain tooling and special tools, the CNC machining center can be used to complete some special process work, such as engraving, engraving lines, and patterns on the metal surface.
From the above introduction, it is not difficult to see that CNC machining centers have a wide range of applications and there are many types of workpieces to be processed. Therefore, many companies need CNC machining centers for the processing of precision parts, molds, etc.
When quoting the prototype project, it is necessary to select the appropriate processing method according to the characteristics of the parts in order to complete the prototype project faster and better. At present, it is mainly engaged in prototype processing, CNC lathe machining, 3D printing, filming, fast molds, etc.. Yijin Hardware, let’s talk about the difference between CNC lathe machining and 3D printing.
First of all, 3D printing is a material increase technology, and CNC lathe machining is a material reduction technology, so they are very different in materials.
1. Differences in materials
Three-dimensional printing materials mainly include liquid resin (SLA), nylon powder (SLS), metal powder (SLM), gypsum powder (full-color printing), sandstone powder (full-color printing), wire (D FM), plate (LOM), etc. .. Liquid resin, nylon powder and metal powder occupy the vast majority of the industrial 3D printing market.
The materials used in CNC lathe machining are all plates, which are plate-like materials. By measuring the length, width and height of the parts + wear, the plates of the corresponding size are cut for processing. CNC lathe machining materials are better than 3D printing. Generally, hardware and plastic plates can be processed by CNC CNC lathes, and the density of the molded parts is higher than that of 3D printing.
2. Differences in parts due to the forming principle
As we mentioned earlier, 3D printing is a kind of additive manufacturing. Its principle is to cut the model into multiple layers/multiple points, and then stack them up layer by layer/point by point, just like building blocks. Same. Therefore, 3D printing can effectively process and produce parts with complex structures, such as hollow parts, while CNC machining is difficult to realize hollow parts processing.
CNC machining is a kind of material reduction manufacturing. Through high-speed operation of various tools, the required parts are cut out according to the programmed knives. Therefore, CNC lathe machining can only have rounded corners of a certain arc, but can not directly process right angles, which can be realized by wire cutting/spark technology. External right-angle CNC lathe machining is no problem. Therefore, the internal right-angled parts can be considered to choose 3D printing processing and production.
It is also the surface. If the surface area of the part is relatively large, it is recommended to choose 3D printing. CNC lathe machining the surface is very time-consuming, and if the programming and operating machine masters are not experienced enough, they cannot leave clear patterns on the parts.
3. Differences in operating software
Most of the 3D printing slicing software is easy to operate, even a layman can use the slicing software proficiently for a day or two under professional guidance. Because the slicing software is very easy to optimize, the support can be automatically generated, which is why 3D printing can reach individual users.
Numerical control programming software is much more complicated and requires professionals to operate it. People with zero basic knowledge generally need to learn about half a year.. In addition, a numerical control operator is required to operate the CNC machining machine.
Because the programming is very complicated, a component can have multiple CNC machining schemes, and 3D printing will only place a small part of the processing time consumables, which is relatively objective.
In recent years, the application of CNC machining centers in the medical device industry has shown a dynamic growth trend. Compared with other mechanical processing industries, the medical device processing industry has very strict requirements on the repeated positioning accuracy, rigidity, processing efficiency, and surface finish and accuracy of CNC machining centers.
According to the special processing requirements of key parts of medical equipment, Yijin hardware CNC machining center accurately matches the processing elements and conditions of medical equipment workpieces, three-axis / five-axis simultaneous processing, and CAD, CAM software, no need to disassemble parts, one time Complete all processing procedures.
Yijin Hardware is equipped with Mitsubishi M80 numerical control system, the spindle speed is 8,000rpm, and the fourth or fifth axis rotation function can be added to process medical equipment parts with complex surfaces, which can meet the requirements of large-scale production.
In order to ensure stable performance quality and high production efficiency, Yijin Hardware adopts CNC machining center equipment with a large-span integral casting structure bed, and the inside of the casting adopts multi-rib reinforcement to improve the shock absorption performance and anti-distortion performance. The whole machine undergoes FEA finite element analysis to optimize static rigidity and dynamic rigidity to ensure accuracy and stable CNC machining and cutting capabilities.
With the continuous progress of the aerospace industry, the research and development of new models has promoted the development of the aerospace parts manufacturing industry. As the machining difficulty of aerospace CNC machining parts such as engine disks, shaft parts, turbine casings, landing gears, etc. continues to increase, various new materials, new structures, and new technologies are emerging in an endless stream, and the requirements for CNC machining technology are also constantly increasing. improve. The aerospace companies are under increasing pressure from CNC machined parts and components manufacturers, and they must be as economical and efficient as possible in order to meet the challenges.
The use of CNC machining technology and cutting tools depends to a large extent on the requirements for parts, materials and processes. Reducing the wall thickness will cause the parts to become extremely unstable, and the use of appropriate coolant also has a great impact on the service life of the tool. Therefore, the stability and clamping stability of the machine tool must be considered in CNC machining, and CNC CNC machining technology And the macro geometry and micro geometry of the cutting tool play a very important role at this time.
Yijin Hardware’s general tool path
Roughing: Under the maximum load of the machine tool, in most cases, the largest possible tool should be selected, the largest possible feed amount, and the fastest possible feed. In the case of the same knife, the feed is inversely proportional to the amount of feed. Under normal circumstances, the load of the machine tool is not a problem. The principle of tool selection is mainly based on whether the two-dimensional angle and three-dimensional arc of the product are too small. After the knife is selected, the knife length is fixed. The principle is that the knife length is greater than the processing depth. For large workpieces, it is necessary to consider whether the chuck interferes.
Light knife: The purpose of the light knife is to achieve the processing requirements of the surface roughness of the workpiece and reserve an appropriate margin. Similarly, the light knife should be as large as possible, and the time as fast as possible, because the fine knife needs a longer time, use the most suitable feed and feed. Under the same feed, the larger the horizontal feed, the faster, the curved surface feed is related to the surface roughness after processing, the size of the feed is related to the surface shape of the curved surface, and the minimum margin is left as long as the surface is not damaged. Quantity, use the largest knife, the fastest speed, and the appropriate feed.
Yijin hardware clamping method
Vise clamping: The clamping height should not be less than 10mm, and the clamping height and processing height must be specified when processing the workpiece. The processing height should be about 5mm higher than the vise plane, the purpose is to ensure the firmness, and at the same time not to damage the vise. This kind of clamping is a general clamping, and the clamping height is also related to the size of the workpiece. The larger the workpiece, the higher the clamping height.
Clamping of the splint: the splint is coded on the worktable, and the workpiece is locked on the splint with screws. This kind of clamping is suitable for workpieces with insufficient clamping height and large processing force, generally medium and large workpieces, and the effect is better.
Code iron clamping: When the workpiece is large, the clamping height is not enough, and the wire is not allowed to be locked at the bottom, the code iron is used for clamping. This kind of clamping needs to be clamped twice. The four corners are first coded, the other parts are processed, and then the four sides are coded to process the four corners. During the second clamping, do not let the workpiece loose, yard first and then loosen. You can also code both sides first and process the other two sides.
Clamping of the tool: the diameter is above 10mm, and the clamping length is not less than 30mm; the diameter is less than 10mm, and the clamping length is not less than 20mm. The clamping of the tool must be firm to prevent collision with the tool and direct insertion of the workpiece.
