Is the processing precision of mechanical spare parts improved, the changes in the industry, the role and effect of these obvious? Following the development of our industry, now some of our metal parts processing is getting better and better, and some cutting work is getting more and more precise, to what extent, as follows tell us. Your answer!
New progress has been made in the processing technology of precision mechanical parts. The processing accuracy of NC metal cutting machine tools has been improved from the original wire level (0.0′mm) to the current micron level (0.00′mm), and some varieties have reached about 0.0 micron. The precision of micro-cutting and grinding of ultra-precision CNC machine tools can reach about 0.0 micron, and the shape precision can reach about 0.0′micron. The precision of special processing with optical, electrical and chemical energy can reach nanometer level (0.00′um).
By optimizing the structure design of machine tools, superfinishing and precise assembly of machine parts, adopting high-precision all-dead-cycle control and dynamic error compensation technologies such as temperature and vibration, the era of sub-micron and nano-scale superfinishing has come into being. The performance of functional components is constantly improving. Functional components are developing towards high speed, high precision, high power and intelligent direction, and have achieved mature applications. All-digital AC servo motor and drive device, high-tech motorized spindle, torque motor, linear motor, high-performance linear rolling components, high-precision spindle unit and other functional components are widely used, which greatly improves the technical level of NC lathe.
