In the wave of high-quality development in modern manufacturing industry, mechanical processing, as a key link in component forming, directly affects product accuracy and production efficiency in terms of its technological level. Currently, a group of commonly used mechanical processing methods, with their mature and reliable characteristics, have become the "main force" on production lines in various industries, providing stable support for fields such as automation equipment, automotive parts, aerospace COMPONENTS, etc.

Turning machining is one of the most widely used methods, mainly for rotating parts such as shafts and disks. Under the operation of a CNC lathe, the cutting tool performs linear motion along the rotation trajectory of the workpiece, which can accurately complete machining of outer circles, inner holes, threads, etc. For example, the outer diameter cutting of 7075 aluminum alloy shaft parts can be controlled within 0.01mm, and is widely used in the production of transmission components for automation equipment.

Milling is skilled in processing complex planes, grooves, and irregular structures. Vertical or horizontal milling machines can machine complex parts such as gears and boxes by coordinating the high-speed rotation of cutting tools with the multi-directional movement of workpieces. Taking DT4C electrical pure iron precision parts as an example, milling can accurately mill the positioning groove of the parts, meeting the strict requirements of electromagnetic components for structural accuracy, and is a key process for the processing of core components of automation equipment.

Although drilling is relatively simple to operate, it is the "basic process" for machining part holes. Radial drilling machines and CNC drilling machines can drill holes of different diameters on metal materials, providing positioning benchmarks for subsequent assembly. In the shell processing of automated equipment, drilling requires drilling bolt holes first, and the accuracy of the hole position directly affects the assembly stability of subsequent components. It is usually required that the hole spacing error does not exceed 0.1mm.

In addition, as the "last hurdle" of high-precision machining, grinding is used to finely polish the surface of parts by high-speed rotation of the grinding wheel, which can control the surface roughness below Ra0.8 μ m. It is commonly used for machining hydraulic valve cores, precision bearings and other parts that require high surface smoothness.

With the advancement of intelligent manufacturing, these commonly used machining methods are deeply integrated with CNC technology and the Internet of Things to achieve automation and digitization of the machining process. Industry insiders say that mastering and optimizing these basic processing methods is still the key to enhancing the core competitiveness of the manufacturing industry, and will lay a solid foundation for the sustainable development of China's high-end equipment manufacturing.
