What are the processing methods of mechanical parts?

If the product batch is large, it is recommended to use lathe for boring, which is fast and accurate. Because it is angle clearing, the boring tool should pay attention to the front angle clearing; If the product batch is small, the milling cutter is used for milling, but the speed is relatively slow. . Machining is the process of changing the shape, size or performance of a workpiece by machining. According to the temperature state of the workpiece, it can be divided into cold working and hot working. Generally, processing at room temperature does not cause chemical or phase change of the workpiece, which is called cold working. Generally, processing above or below normal temperature will cause chemical or phase change of the workpiece, which is called hot processing. According to different processing methods, cold working can be divided into cutting processing and pressure processing. Hot working usually includes heat treatment, forging, casting and welding. There are mainly turning, milling, winding and grinding. Traditional machining methods mainly include turning, milling, planing, grinding, drilling and boring. Milling: the plane or inclined plane is mainly processed, and the plane is removed by the milling cutter head; Planing: mainly processing plane or curved surface, and removing plane or curved surface with planer; Grinding: grinding plane, outer circle and inner circle with grinding wheel to make them reach surface roughness; Drilling: mainly drilling with a drill bit; Boring: mainly boring the inner hole with boring cutter or boring cutter. Mechanical processing can be divided into cold processing, hot processing, chemical processing and special processing. There are many methods, rigorous processes, high technical content, involving a wide range of disciplines, many employees and great social contributions.
