Machining methods of mechanical parts - commonly used machining methods
Machining methods of mechanical parts are mainly divided into: turning, milling, planing, drilling, grinding, etc. The commonly used machining methods are introduced one by one.
Turning: Turning is a method of cutting the rotating surface of a workpiece with a turning tool on a lathe. It is mainly used to process rotating surfaces and helical surfaces on various shafts, sleeves and disc parts, including: inner and outer cylindrical surfaces, inner and outer conical surfaces, inner and outer threads, forming rotary surfaces, end faces, grooves and knurling Wait. In addition, it can also drill, ream, ream, tap and so on.
Milling: Milling is mainly used for roughing and semi-finishing of various planes, various grooves, etc., and a fixed surface can also be processed with a forming milling cutter . It can mill planes, stepped surfaces, formed surfaces, helical surfaces, keyways, T-slots, dovetails, threads, teeth, etc.
Planing: Planing is a method of using a planer to cut on a planer. It is mainly used to process various planes, grooves and racks, spur gears, splines and other busbars that are straight. noodle. Planing is more stable than milling, but the machining accuracy is lower and the tool is easily damaged. It is less used in mass production and is often replaced by milling and broaching with higher productivity.
Drilling and boring: Both drilling and boring are methods of making holes. Drilling includes drilling, reaming, reaming and countersinking. Among them, drilling, reaming and reaming belong to the roughing, semi-finishing and finishing of holes, commonly known as 'drilling-expanding-reaming'. The drilling accuracy is low. In order to improve the accuracy and surface quality, reaming and reaming should be continued after drilling. The drilling process is carried out on a drilling machine. Boring is a cutting method that uses a boring tool to perform subsequent processing of prefabricated holes on a workpiece on a boring machine.
