1, precision machining surface of each piece is easy assurance; when machining the workpiece around a fixed axis of rotation, each surface having the same axis of rotation, it is easy to ensure that the requirements of concentricity between the working surface;
2, the cutting process is relatively stable; in addition to intermittent surface outside lathing process generally is carried out continuously, unlike the milling and planing, in one pass process, the cutter has repeatedly cut and cut, resulting in impact;
3, for non-ferrous metal parts finishing; some non-ferrous metal parts, because the material itself is low hardness, ductility is good, with the other processing methods difficult to get smooth surface;
4, the tool is simple; Tool is one of the simplest tools, manufacturing, sharpening and easy installation, which facilitates the processing according to the specific requirements, use reasonable perspective.
