What is the classification of metal cutting process

Metal cutting process is divided into turning, milling, planing, grinding, drilling, boring. Specifically as follows:

1, lathe refers to the workpiece rotation as the main movement, the lathe tool moves for the feed movement processing rotary surface of the machine tool. It can be used to process a variety of rotary molding surface, such as: internal and external cylindrical surface, internal and external conical surface, internal and external threads, as well as end faces, grooves, knurling, etc.. It is the most widely used metal cutting machine tool, the longest production history, the most varieties of a machine tool. There are many types of lathe models, according to its use, the structure can be divided into: instrument lathe, horizontal lathe, single-axis automatic lathe, multi-axis automatic and semi-automatic lathe, turret lathe, vertical lathe, multi-tool semiautomatic lathe, specialized lathe and so on. In recent years, computer technology has been widely used in the machine tool manufacturing industry, with the emergence of CNC lathes, turning machining centers and other mechatronic products.

2, milling machine refers to the main milling cutter on the workpiece processing various surfaces of the machine tool. Usually the rotary movement of the milling cutter as the main movement, the workpiece (and) the movement of the milling cutter for the feed movement. It can process the plane, groove, but also can process a variety of curved surfaces, gears and so on.

3, planer is a machine tool that uses a planer cutter to process the surface of the workpiece. The tool and the workpiece to do relative linear motion for processing, mainly for a variety of plane and groove processing, can also be used for linear molding surface processing.

4, grinding machine refers to the use of abrasives or abrasive processing workpiece surface machine tools. Generally used for parts hardened surface grinding process. Usually, the abrasive rotating main movement, the workpiece or abrasive movement for the feed movement, its wide range of applications, high processing accuracy, surface roughness Ra value is small.

5, the drilling machine refers to the main use of drills in the workpiece hole processing machine tools. Usually the drill rotates as the main movement, and the drill moves axially as the feed movement. Drilling machine structure is simple, relatively low precision, can drill through holes, blind holes, replacement of special tools, can expand, countersinking, reaming or tapping and other processing.

6, boring machine refers to the main boring tool in the workpiece processing has been prefabricated hole machine tools. Usually, the boring tool rotation for the main movement, boring tool or workpiece movement for the feed movement. It is mainly used for processing high-precision holes or a positioning to complete a number of holes in the finishing process, in addition to other machining surfaces can also be engaged in the finishing of holes related to the processing.
