The processes commonly used in machining usually include the following：

1.  Turning

Turning is the most common process for manufacturing round parts. The lathe positions the material, ensures its height is correct, and then uses tools to whittle it into the desired shape and size. The size and function of the lathe depends on the size and shape of the workpiece to be machined.

2.  Milling

Milling is a process that can be worked on a plane, inside radius, and outside radius. Milling machines use rotary tools to cut the workpiece out of the material and form surfaces of different shapes.

3.  Drilling

Drilling is a process mainly used for drilling holes. The operation is usually simple and relatively fast. Drill presses are commonly used to drill holes in different types of materials.

4.  Grinding

Grinding is the most common process in grinding machines and is used to improve the quality and accuracy of parts processing. Grinding machines are usually used for surface grinding, external grinding and internal grinding.

5.  Cutting

Cutting is a process used to cut and separate materials and other processes. Cutters are usually used to cut large materials or plates, including metal, wood and plastic.
