[Industrial Knowledge] Analysis on the processing technology of metal components on CNC milling machine Going by the existing scenario, the main step for domestic ventures to process metal parts is to choose an ideal typical CNC milling equipment, and after that reduced the metal components and brighten them. As a vital approach of cutting steel elements, crushing primarily depends on making use of multi-edged tools to complete the cutting, yet its core is a milling machine. The adjustments in the skills of CNC milling machines at home and abroad have made CNC milling equipment a powerful tool for handling metal elements. After talking about the CNC milling process and its features, this research study describes the use of the CNC milling procedure in practice, as well as talks about the administration of the CNC milling process, in the hope that it can offer advantageous understanding for the use of the procedure skills.
