The CNC router is an intelligent numerical control (computer numerical control) processing equipment. CNC routers generally have two main drive systems, namely, ball screw and rack rail drive. Therefore, choosing a reasonable router equipment configuration can improve processing accuracy and production efficiency and increase the service life of woodworking engraving machine equipment. The CNC router is generally composed of a CNC operating system, CNC processing software, spindle, transmission system, and vacuum table. The latest Zhima series CNC router produced by Shandong U-May CNC Technology Co., Ltd. is composed of a 200*300 mm square tube welded thick bed, a side hanging structure, a cast iron column and a 150*200 mm gantry. The legs can be separated freely, saving packaging and transportation costs.
