Machining is a process of changing the shape size or performance of a workpiece with a machining machine. According to the workpiece is in the temperature state, divided into cold processing and hot processing. Generally at room temperature processing, and do not cause the chemical or phase changes of the workpiece is called cold processing. High or low temperature processing equipment usually causes chemical or phase changes of the workpiece. Cold machining can be divided into machining and pressure machining according to the difference of machining mode. Hot processing is often heat - treated and hot - calcined - cast and welding.

In addition, hot and cold treatment is often used during assembly. For example, bearings in assembly are often put the inner ring into liquid nitrogen to cool down its size, the outer ring is properly heated to enlarge its size, and then assembled together. The outer rim of the train's wheels is also heated to a base, which is then cooled to ensure the firm bonding (which is still used in the transfer of some parts). Machining includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roller forming, metal sheet bending forming, die forging, water jet cutting, precision welding, etc. Machining: machining in broad sense means the process of manufacturing products by mechanical means. A narrow idea is the process of making parts with special machines such as Lathe Machine, Milling Machine, Driling Machine, Grinding Machine, punching Machine and die-casting Machine.

Mechanical processing need by digital milling machine, digital display molding grinding machine, digital lathe, electric spark machine, universal grinding machine, machining center, laser welding, in silk, etc., can be precision parts of cars, milling, planing, grinding and other processing, such machinery specialize in precision parts of the car, milling, planing, grinding, such as processing, processing can be all kinds of irregular shape parts, machining precision can be up to 2 microns
