CNC turning parts are mainly used to manufacture helicoid parts, like bearings and wheels. By operating the CNC machining program, the cutting of internal and external of columns, cone, surface, whorl and end face, slot turning, drilling, reaming, and fraising can be done automatically with high precision. But for CNC, no matter it is manual programmed or automatic programmed, the technology analysis of the target parts has to be done before the programming, like the cutting point, manufacturing route, as well as manufacturing plan, suitable cutter and quantity of cutting. Finally, only the accurate control of the precision can produce qualified products.
CNC machining precision parts are high precision parts that produced by manufacturers according to the drawings. The precision of CNC machine is different from the precision of processing technique. They are two different conceptions of CNC machining. The former is the precision of the machine itself, and the latter is the precision degree of processing technique. The two conceptions seem independent, but they relate closely to the precision of the parts to be produced.
