Machining is a process in which the dimensions or properties of the workpiece are changed by machining machinery. According to the temperature state of the workpiece being processed, it is divided into cold processing and hot processing. Generally processed at room temperature, and does not cause chemical or phase changes in the workpiece, called cold processing. Generally higher or lower than normal temperature processing, will cause the workpiece chemical or phase changes, called hot processing. Cold machining can be divided into cutting machining and pressure machining according to the difference of processing methods. The common hot work is heat treatment, calcination, casting and welding. In addition, hot and cold treatment is often used in assembly. For example, when bearings are assembled, the inner ring is often put into liquid nitrogen to cool it to shrink its size, and the outer ring is properly heated to enlarge its size, and then it is assembled together. The outer rings of train wheels are also heated and attached to the substrate, so that they can be fastened securely when cooled (this method is still used in the transfer of some parts). Mechanical processing includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging, water jet cutting, precision welding, etc. Machining: The broad meaning of machining refers to the process of making products by mechanical means; The narrow meaning is to use lathes, milling machines, drilling machines, grinding machines, punching machines. In the process of precision machining will be useful many equipment, the following list of some commonly used machinery equipment: Such as wire cutting, discharge processing machine, deep hole discharge processing machine, CNC optical projection grinding machine, tool grinding machine, universal grinding machine, NC coreless grinding machine, surface grinding machine, inner and outer diameter grinding machine, precision surface grinding machine, precision forming grinder, large water mill, NC milling machine, grinding machine, machining center, PVD titanium plating machine, laser welding machine, carbonized water cleaning machine, cylinder grinding machine, vacuum hot place Furnace cleaning and so on.
