Has the machining accuracy of mechanical parts been improved?

 Has the machining precision of mechanical parts been improved? Are the changes in the industry and the effects and effects obvious? Following the development of our industry, now some of our metal parts processing are getting better and better, and some cutting jobs are also increasing. The more accurate, how accurate is it, the following tells you the answer!

There have been new advances in the processing technology of precision mechanical parts. The processing accuracy of CNC metal cutting machine tools has been upgraded from the original silk level (0.0'mm) to the current micron level (0.00'mm), and some varieties have reached about 0.0μm. The precision of micro cutting and grinding of ultra-precision CNC machine tools can reach about 0.0μm and the shape accuracy can reach about 0.0'μm. The precision of special processing using light, electricity, and chemical energy can reach nanometer level (0.00’μm).

Through the optimization of machine tool structure design, super-finishing and precise assembly of machine parts, and the use of high-precision full-loop control and dynamic error compensation technologies such as temperature and vibration, it has entered the era of sub-micron and nano-level super-finishing. The performance of functional components continues to improve. Functional components continue to develop in the direction of high speed, high precision, high power and intelligence, and have achieved mature applications. Fully digital AC servo motors and drive devices, high-tech electric spindles, torque motors, linear motors, high-performance linear rolling components, high-precision spindle units and other functional components are popularized and applied, which greatly improves the technical level of CNC lathes.
