What are the basic methods of machining

There are many kinds of metal cutting methods, which vary according to the specific requirements and conditions of the processed parts. There are also certain differences in the selection of processing methods. In the process of actual production, the main processing methods of parts often used are turning, drilling, boring, planing, broaching, milling and grinding.
Although there are many similarities in the principle of machining, the form of cutting motion is different, so the machine tools and tools used are also very different. Therefore, it has its own process characteristics and application scope.

1. Turning
Ordinary machine tools are the most common machine tools for turning workpieces. It mainly relies on the linear movement of the tool and the rotary movement of the part as the feed movement. Turning is the process of cutting metal from a workpiece. While the workpiece rotates, the tool cuts into the workpiece or turns along the workpiece. It is more suitable for machining the rotary surface.
The main characteristics of turning are easy to ensure the position accuracy of the workpiece, high production efficiency, low production cost and suitable for a wide range of processing materials.

2. Drilling
Drilling is the processing of drilling holes on solid metal, mainly for axial feed movement. The application of drilling is mainly in single piece and small batch production. In batch or mass production, in order to ensure the accuracy of processing, group massage and multi axis cobalt are used to process holes. In addition to drilling, the drilling machine can also perform other processing. When drilling, the workpiece is clamped and fixed; The drill bit rotates while drilling into the workpiece.
3. Boring
Boring is a processing method to enlarge or further process the drilled or cast hole on the metal workpiece. Boring mainly refers to the rotation of the boring tool. The boring process is mostly carried out on milling and boring machines and boring machines.

4. Ox head planing, dragon door planing and slotting
Planing mainly involves plane processing. It is a common processing method in plane processing of single piece and small batch production. The most common processing methods are ox head planing, dragon door planing and slotting. When machining with a planer, the workpiece is fed to the cutter, and the cutter moves back and forth on the workpiece.
The process characteristics of planing mainly include good universality, low production efficiency and low processing accuracy. It is widely used in maintenance workshop and mold workshop. Planing is mainly used for small batch production of single piece. Su ri'an planing is mainly used for plane processing, but it is also helpful for processing straight grooves.

5. Broaching
The axial movement of broach under the action of tension. Good performance for machining the inner and outer surfaces of workpieces. Broach has a complex structure, high cost in manufacturing, and there are certain special types, so broaching is mainly used for mass production. Broaching is characterized by high production efficiency, high machining accuracy and simple broaching machine structure.

6. Milling
Milling is the process of cutting metal with rotary tools, mainly used for plane processing. The commonly used machine tools are horizontal milling machines or vertical milling machines. It has the technological characteristics of high production efficiency and good heat dissipation of cutter teeth. In single piece and small batch production, the lifting table milling machine is used for processing small and medium workpieces, and the gantry milling machine is used for processing large workpieces.

7. Grinding
Grinding is mainly the processing of the working surface. The grinding process is characterized by high grinding accuracy, good processing for some difficult and easy to process materials, and high cutting speed.
