What is machining?

Machining refers to the use of mechanical equipment to cut or process raw materials in order to achieve the manufacturing parts. Mechanical processing technology is an indispensable part of modern manufacturing, capable of producing high-precision parts and components, widely used in fields such as aircraft, aerospace, automobiles, electronics, ships, and healthcare.

Machining is generally divided into two types: metal processing and non-metal processing. Among them, metal processing mainly includes casting, forging, welding, and cold working, while non-metal processing includes the processing of materials such as plastic, glass and wood.

The machining methods mainly include cutting, grinding, forming, and welding.

1. Cutting processing. It is a machining method that uses machine tools to form cutting edges and cut workpieces. Cutting processing can be divided into turning processing, milling processing, drilling processing, and boring processing according to the processing method.

2. Grinding processing refers to the use of grinding tools to grind the surface of a workpiece into the desired shape and size. Grinding processing is usually carried out after cutting processing to improve the surface roughness and accuracy of the workpiece.

3. Forming processing, is the use of the process properties of plastic materials to process workpieces into the desired shape and size through pressure and thermal deformation. Forming processing includes forging, stretching, bending, stamping, deep drawing, and spinning processes.

4. Welding processing is a processing method that connects multiple parts through high temperature or high pressure to form a whole. Welding processing is widely used in fields such as automobiles, engineering machinery, construction, and ships.

Machining is widely used in the field of industrial manufacturing, including the following aspects.

1. Automobile manufacturing. In automobile manufacturing, machining technology is widely used in various aspects such as engines and components, steering gears, braking systems, suspension systems, transmissions, and vehicle bodies.

2. Machine tool manufacturing. Machine tools are the infrastructure of the mechanical processing industry and play a crucial role in precision machining. Machining technology is widely used in the manufacturing process of machine tools.

3. Mold manufacturing. Machining is also widely used in the field of mold manufacturing, such as injection molds, die-casting molds, stamping molds, etc.

4. Precision instrument manufacturing. Machining technology is also widely used in precision instrument manufacturing, such as microscopes, lasers, optical instruments, semiconductor processing
