Computer boring, in fact, refers to the use of CNC milling machines for fine parts processing. CNC computer processing is realized by CNC milling machine, and CNC milling machine is controlled by CNC technology (program). The error is very small and the precision is high. Therefore, the precision of Shenzhen computer processing is very high. CNC milling processing should be based on the shortest route and ensure accuracy when selecting roads for processing.
