Machining classification

Mechanical processing mainly includes manual processing and numerical control processing. Manual processing refers to the method of processing various materials through manual operation of mechanical equipment such as milling machine, lathe, drilling machine and sawing machine. Manual processing is suitable for small batch and simple parts production. Numerical control machining (CNC) refers to the use of CNC equipment by machinists for machining, which includes machining bases, turning and milling bases, WEDM equipment, thread cutting machines, etc. The vast majority of machining workshops use CNC machining technology. After programming, the azimuth coordinates (X, Y, Z) of the workpiece in the Cartesian coordinate system are converted into program language. The CNC controller of the numerical control machine tool controls the axis of the numerical control machine tool by identifying the width and interpreting the program language, and takes the initiative to remove the data as required, and then obtains the precision workpiece. NC machining processes workpieces in a continuous way, which is suitable for large quantities of parts with disordered shapes.
