CNC Machining is frequently the last step in metallic manufacturing, sometimes the only process involved. Compared to different metalworking techniques, CNC machining
can meet the tightest endurance and producing the many accurate, fine products over and over again.
It is important to break the passage down into two different parts:
First, the process of removing all metal with the assist of automatic equipment has been around for centuries. Machining process include: broaching and grinding, shaping, turning, drilling and milling,
Next one is NC is an abbreviation of Numerical Control in old machining; an operator must control the motion of a machine tool. Numeric control, first developed in the 1940s, governs the motion of machines mechanically, through the set instruction manual.
