Processing instructions: CNC, also known as computer gong, CNCCH or CNC milling machine, is a new type of machining technology. Its main task is to program machining processes through computer programming instead of manual labor. The parts produced by CNC punching machines have stable quality, high processing accuracy, and high repeatability. CNC machining can produce parts with complex shapes that cannot be completed by manual processing. CNC machining technology has now been widely promoted. The most common CNC machining methods in typical machining workshops are CNC milling, CNC turning, and CNC EDM wire cutting.
