Machining is a manufacturing method that uses machine tools to precisely cut, shape, and process raw materials. It is a widely used manufacturing process used to make a variety of industrial, automotive, electronics, medical and aerospace products. Here are some basic introductions to machining:

1. Processing purpose: The main purpose of machining is to process raw materials (usually metal or plastic) into the required shape, size and surface quality through cutting, drilling, milling, grinding, turning, cold heading and other processes. to meet specific engineering or design requirements.

2. Machine Tools: Machining is usually done on specialized machine tools or machine tools. Different types of machine tools include lathes, milling machines, drill presses, grinders, cold heading machines, etc. Each machine tool is used for different types of machining operations.

3. Materials: Machining can be used on various materials such as metals (such as aluminum, steel, copper, stainless steel), plastics, and ceramics. Different materials require different cutting tools and parameters.

4. Cutting Tools: Cutting tools are vital elements in machining. They are usually made of carbide, high-speed steel or ceramic and are used to cut or shape raw materials.

5. CNC technology: Computer numerical control (CNC) technology is widely used in machining. It uses a computer control system to precisely control the movement and operation of machine tools to achieve high-precision machining.

6. Further processes: Machining is usually only part of the manufacturing process. Depending on the needs of the product, other processes may be required after machining, such as welding, heat treatment, electroplating, spraying, etc.

7. Application fields: Machining is used in many fields, including automobile manufacturing, aerospace, medical equipment, electronics, shipbuilding, etc.

Machining is a highly precise manufacturing method that allows the production of high-quality, to-specification parts and products. In modern manufacturing, it is used along with other manufacturing technologies such as injection molding, 3D printing, etc. to meet various industrial needs.
