The market share of domestic popular CNC systems continues to increase, but foreign brands still occupy the domestic market. In the field of high-end CNC systems, there is indeed a relatively large gap between domestic CNC systems and foreign countries. Although the domestic five-axis linkage numerical control system has made some breakthroughs in technology, the functions are not perfect enough, and the verification in practical applications is not yet comprehensive. The gap between domestic high-end CNC systems is also manifested in the incomplete serialization of products, such as servo motors and servo drives with various specifications from small to large, which are available abroad, but our specifications are limited; Above), high-precision (resolution below 0.1 micron), multi-channel CNC system functions and performance, there is a big gap between domestic systems and foreign systems.
