The meaning, classification, app store and future development analysis of CNC ultra-precision machining

Release time:2024-12-24     Number of views :


  Many CNC processing manufacturers have emphasized the precision of precision machining, nothing more than how meticulous the control of product quality tolerances can be, for example, the accuracy can reach 0.01mm, 0.005mm, 0.002mm, of course, when we choose the numerical control machine, the manual is indeed marked with the precision of its processing, and most of them are marked to the processing accuracy can reach 0.005 or less, in fact, can really achieve such precision, I am afraid that many processing manufacturers do not have the corresponding detection instrument to measure it. Shenzhen EMAR Precision Technology is based on medical, communication and optical components, and has developed precision machining services for automotive, communication and automation parts. It has taken the lead in passing the IATF16949 quality management certification and carried out strict implementation. The company is equipped with projectors, three-coordinate detectors, spectrometers and other precision testing equipment. Today, let‘s talk about what ultra-precision machining is and what fields ultra-precision machining will be used in. Let‘s take a look.

The meaning, classification, app store and future development analysis of CNC ultra-precision machining(pic1)  The meaning of ultra-precision machining:

  In the field of machining, ultra-precision machining technology is designed to improve the performance, quality, lifespan, and reliability of mechanical and electrical products, and to save materials and energy as an important way. In life, we can come into contact with, for example, cylinders with high piston processing accuracy, which can effectively improve the efficiency and horsepower of the engine and reduce the fuel consumption of the engine. If the processing accuracy of rolling elements and raceways of rolling bearings is improved, it is conceivable that the bearing speed can be increased and vibration and noise can be effectively reduced. If the processing accuracy of the disk plane is improved, the gap between it and the magnetic head can be effectively reduced, which can greatly improve the storage capacity of the disk. If the marking accuracy of semiconductors can be improved, the integration of electronic chips can be effectively improved.

  Second, the standards for ultra-precision machining:

  At present, some factories in developed countries can control the processing accuracy of about 3μm, our country can control the processing precision of 5μm, so we can only call precision machining below this value, better than this value can be called high-precision machining or ultra-precision machining.

  At the same time, the industry has also given some definitions, which are mainly divided into three grades: A, machining precision of 3~ 0.3μm, roughness of 0.3~ 0.03μm is called precision machining; B, machining accuracy of 0.3~ 0.03μm, roughness of 0.03~ 0.005μm is called ultra-precision machining, also known as sub-micron machining; C, machining precision of 0.03μm (30 nm), roughness of more than 0.005μm is called nano (nm) machining. CNC Machining in the field of precision and ultra-precision machining is currently mainly used in the car, grinding, grinding, polishing, etc.

  So far, the application of precision machining and ultra-precision machining technology in China has not been limited to national defense cutting-edge products and aerospace fields. It has long been extended to the civilian field, and the scale of use is also growing rapidly. For example, in the computer, communication, film and television media industries, precision and ultra-precision machining equipment are used to meet the rapidly developing support conditions. Computer disks, camera lenses, laser prism, photocopier and printer photosensitive parts, etc., are all efficient ultra-precision machining technology and large-scale automated production processes.

  In developed countries such as the United Kingdom, Japan, the United States, Germany, and the Netherlands, ultra-precision machining technology is currently in a leading position in the world. This technology is not only applicable to the military sector, but also actively extends to the production of civilian products.

  IV. Future development of ultra-precision machining:

  We can predict that in the future, China will focus on ultra-high-efficiency, ultra-high-precision machining lathes, CNC machining centers, and composite machining machines, ultra-precision cylindrical mills, and surface grinders to develop the application process of ultra-precision machining technology, so as to promote the development of a number of ultra-precision basic functional components, such as imported shafts, servo motor feed systems, measurement systems, and automatic error compensation systems, in order to better meet the development needs of high-tech industries such as aviation, aerospace products, and computers.
