In the process of operation, precision machining is a process of using processing equipment to change the size or characteristics of the product workpiece. Precision machining can be divided into a certain level according to the temperature of the product workpiece being processed. Cold drawn and heat treated. It is generally processed at room temperature and does not cause organic chemistry or phase transformation of the product workpiece, which is called cold drawing. Precision machining is generally processed at higher or lower than normal temperature, which will immediately cause the organic chemistry or phase transformation of the product workpiece. It is reasonably called heat treatment. Cold drawing can be divided into drilling according to the difference in processing methods. Cutting and working pressure processing. Heat treatment generally includes heat treatment process, forging, forging and electric welding. Precision machining is mainly the process of modifying the size or function of the product workpiece according to its various mechanical equipment. According to the temperature of the processed product, it is divided into cold drawing and heat treatment. Among them, the technological process in mechanical processing and manufacturing refers to the detailed address in a job, and the process that has some professional skills for the continuous completion of one or a group of product workpieces. The main characteristic that composes a technological process is not to modify the overall processing goal, machine equipment and operators, and the content of the technological process is continuously completed. The professional skills process can be divided into the following two processes.
