1. Easy to ensure the accuracy of various machining surfaces of the workpiece; During processing, the workpiece rotates around a fixed axis, and each surface has the same axis of rotation, making it easy to ensure the coaxiality requirements between the processing surfaces;
2. The cutting process is relatively stable; Except for intermittent surfaces, in general, the lathe machining process is continuous, unlike milling and planing, where the cutting teeth have multiple cuts in and out during a single step, resulting in impact;
3. Suitable for precision machining of non-ferrous metal parts; Due to the low hardness and good plasticity of certain non-ferrous metal parts, it is difficult to obtain a smooth surface using other processing methods;
4. Simple cutting tools; Turning tool is the simplest type of cutting tool, which is easy to manufacture, grind and install. This makes it convenient to choose a reasonable angle according to specific machining requirements.
