Machining refers to the use of mechanical equipment to cut raw materials, forming, assembly and other processing methods, there are a variety of common machining methods, the following will be some of the common machining methods are introduced.

1. Turning

Turning is a common metal processing method, which mainly uses the lathe to fix the workpiece on the spindle, and then drives the cutting tool to rotate along the axis of the workpiece through the spindle to achieve the purpose of machining the workpiece. Turning can realize the processing of the outer circle, inner circle, end face and other shapes of the workpiece, and is widely used in the processing of various parts.

2. Milling

Milling is a processing method carried out by milling machine, which is a common three-dimensional cutting processing method. The milling method can realize the machining of the workpiece plane, surface, inner and outer contour and other shapes, and is suitable for the processing of various metal and non-metal workpieces. Milling is more flexible than turning and can be used to process complex curved parts.

3. Drilling

Drilling is a processing method with a drilling machine as the main equipment, which is mainly used to process holes. The drilling machine can realize the machining of different shapes such as positioning hole, through hole and blind hole by rotating tool. Drilling is a common metal processing method, which is widely used in the manufacture of various parts.

4. Grinding

Grinding is a machining method that uses abrasive materials such as grinding wheels to cut, mainly used for precision machining of workpieces. Grinding can realize high-precision machining of the plane, outer circle and inner hole of the workpiece, and can improve the surface quality and dimensional accuracy of the workpiece. Grinding is suitable for the processing of metal and non-metal materials of various hardness.

5. Forging

Forging is a method of metal processing using forging equipment, mainly through the forging die to plastic deformation of the metal, so as to change its shape and mechanical properties. Forging can be divided into two ways of cold forging and hot forging, which can achieve the production of parts of various shapes and sizes. Forging is a common metal processing method, widely used in machinery manufacturing, aerospace and other fields.

6. Stamping

Stamping is a method of processing sheet metal through a metal punch, which mainly uses a punch to impact the sheet metal, so that it can be deformed or cut. Stamping is suitable for mass production of parts and can quickly and efficiently achieve the forming and processing of the workpiece. Stamping is widely used in automotive, home appliances, electronics and other industries.

7. Sand casting

Sand casting is a common casting method, mainly used to produce large, complex shapes of castings. Sand casting by casting molten metal in the sand mold, after the metal solidifies, the sand mold can be removed to obtain the casting. Sand casting is suitable for the casting of various alloys and non-ferrous metals, which can achieve mass production of workpieces.

The above are some common machining methods, each processing method has its own characteristics and scope of application, through flexible combination and selection of appropriate processing methods, you can achieve the processing needs of various shapes and materials of parts. Machining methods are of great significance in modern industrial production and provide strong support for the manufacturing and processing of products.
