Mechanical processing is generally processed at a state higher or lower than normal temperature, which will directly cause chemical or physical phase changes of the workpiece, effectively called hot processing, and cold processing can be divided into cutting processing and pressure processing according to the difference in processing methods. . Common thermal processing includes heat treatment, forging, casting and welding.
Machining is mainly the process of changing the dimensions or functions of the workpiece through its various machines. According to the temperature of the workpiece to be processed, it is divided into cold working and hot working. Among them, the process in machining refers to the technical process that is continuously completed for one or a group of workpieces at a work location. The primary characteristics of a process are that the processing target, equipment and operators are not changed, and the content of the process is continuous. The skill process can be divided into the following two steps.
The technical specification of machining is one of the technical documents that regulate the technical process and operation methods of parts machining. After approval, it is used to guide production. The mechanical processing technical regulations usually include the following contents: the technical road of workpiece processing, the specific content of each process and the equipment and technical equipment used, the inspection items and inspection methods of the workpiece, the amount of cutting, the time quota, etc.
Fine parts processing technology is to change the shape, size, relative orientation and nature of the production target on the basis of the process, so that it becomes a finished product or semi-finished product. It is the specific description of each process and each process. For example, the above mentioned , Roughing may include blanking, grinding, etc., and finishing may be divided into lathes, fitters, milling machines, and so on.
