  • What Is Cnc Cutting?

    CNC cutting technology is an organic combination of traditional processing technology and computer numerical control technology, computer aided design and auxiliary manufacturing technology. CNC cutting consists of two parts: the numerical control system and the mechanical structure. Compared with traditional manual and semi-automatic cutting, CNC cutting can effectively control and improve cutting quality and cutting efficiency through the cutting technology, cutting process and automatic control technology provided by the numerical control system.
