Among the CNC numerical control machine tools in China, there are 2l030 CNC lathes, accounting for 84% of CNC metal cutting machine tools, domestically produced 18050 units, and imported 2980 units, with an import rate of 17%. The technical complexity is relatively simple, and the number of domestically produced CNCs is relatively large. A considerable part of the lathe is an economical CNC lathe, which reflects to a certain extent the poor quality of CNC machine tools in China.
The medium-sized varieties are relatively complete, lacking large and high-precision varieties, especially the lack of ultra-precision CNC lathes. In 1997, 1,804 CNC lathes were imported and 3,16 were exported. Most of the imported ones were CNC lathes and turning centers with high precision. CNC lathe key development products (1) CNC ultra-precision lathe; (2) turning and milling center; (3) precision turning center.
Foreign CNC lathes not only have complete specifications, but also develop in the direction of turning centers, such as FMC for turning parts, FMC for shaft turning centers, and turning and milling centers that combine the functions of turning centers and machining centers. The automotive industry is a major demand for such CNC lathes.
The annual demand for CNC lathes is about 1,500 units, including 100 precision turning centers and milling and milling centers. 21 Development direction and focus On the basis of continuing to develop full-featured CNC lathes, we will focus on the development of turning centers for double-spindle and double-turret tool holders.
It is required to have good precision retention and high reliability, and the price is about 500,000 yuan. The turning and milling center of the opposite twin-spindle and double-turret tool holders is a key product for development. In addition to the large-scale turning and milling centers, ultra-precision CNC lathes and precision turning centers as key processing equipment should also focus on breaking through its key technologies.
