(1) Ordinary turning: It is suitable for the cylindrical machining of various batches of shaft parts, and is widely used. Single-piece small batches are often turned by bedroom lathes; for medium batches and mass production, automatic, semi-automatic and special lathes are used to complete turning.
 
(2) CNC turning: suitable for single-piece small batch and medium batch production. In recent years, the application has become more and more common, and its main advantages are good flexibility, short equipment adjustment and preparation time when replacing machined parts; less auxiliary time during machining, which can improve efficiency by optimizing cutting parameters and adaptive control; There are few fixtures, and the corresponding production preparation cost is low; the technical requirements of machine tool operation are low, and it is not affected by the skills, vision, spirit, physical strength and other factors of the operator.
