Automobile machining refers to the technical process of processing and manufacturing automobile engine, transmission system, chassis and other parts. Automobile machining technology is an indispensable technology in the modern automobile industry, and its quality and precision are directly related to the performance and safety of automobiles. Automobile machining includes many links, including casting, forging, stamping, welding, sheet metal, cutting, heat treatment, surface treatment, etc.

 Cutting is one of the core technologies of automotive machining. Its main function is to remove excess material on the workpiece by cutting to obtain the required shape and size. Commonly used automotive machining cutting processes include turning, boring, milling, drilling and so on. Among them, turning is the most commonly used processing method. It rotates the workpiece and the tool to make the tool cut along the surface of the workpiece to obtain the desired shape and size. Boring is achieved by rotating the tool and workpiece so that the tool cuts along the internal surface of the workpiece to obtain the desired internal shape and size. Milling is by rotating the tool and the workpiece so that the tool cuts along the surface of the workpiece to obtain the desired shape of the plane and the surface. Drilling is to rotate the drill bit and the workpiece so that the drill bit cuts along the surface of the workpiece to obtain the desired shape and size of the hole.

 In addition to cutting, automotive machining also includes heat treatment and surface treatment. Heat treatment refers to changing the structure and properties of metal materials by means of heating and cooling, thereby improving their hardness, strength and other properties. Commonly used heat treatment methods include quenching, tempering, normalizing, and annealing. Surface treatment refers to a series of treatments on the surface of the workpiece to make it have certain wear resistance, corrosion resistance, aesthetics and decoration. Commonly used surface treatment methods include electroplating, spraying, sandblasting, polishing, etc.
