1, Technology; Traditional machining whether positioning, clamping, cutting tools, cutting can be simple machining; CNC machining is more complex, but can be processed to multiple parts at the same time, high precision.
2, clamping aspect; In the traditional machining, the machine tool itself machining capacity is limited, need to clamp several times. And CNC machining in most cases do not need special fixture, the cost is low.
CNC machining is evolved from the traditional manual machining, is based on ordinary machine tools and computer digital control technology, computer aided 3D design research and development design of new CNC machine tool machining.
machining technology; Traditional manual machining, whether positioning, clamping, tool, cutting and other options can be simple machining. But CNC machining is more complex, need to consider these factors in numerical control procedures, even if the same machining task, CNC machining also has a number of programs, can be processed at the same time on a number of machining parts, at the same time machining accuracy can be up to ±0.01mm, this is the ordinary machine machining can not do.
Clamping technology; In the ordinary machine machining, because the machine itself machining capacity is limited, so in the machining need to be many times clamping. And need to use special fixture, resulting in higher fixture cost, virtually increased production cost. And CNC machining positioning clamping is used to debug the instrument, most cases do not need special fixture, so the cost is low.
