  • What Is Machining

    Update:2021-12-29 

    Machining is a process of using machining machines to change the shape size or performance of the workpiece. According to the workpiece to be processed in the temperature state, divided into cold processing and hot processing. Generally in normal temperature processing, and does not cause the workpiece chemical or phase changes, called cold processing.Generally in higher or lower than the normal temperature of the processing, will cause the workpiece chemical or phase changes, called thermal processing.Cold machining can be divided into cutting and pressure machining according to the difference of machining mode.There are heat treatment, calcination, casting and welding.

    Mechanical processing refers to the process of manufacturing products by mechanical means;The narrow meaning is to use the Lathe (Lathe Machine), Milling Machine, CNC Machine), drilling Machine, Driling Machine), Grinding Machine, Grinding Machine), punching Machine, die-casting Machine Machine special mechanical equipment such as the process of production parts.

    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

    In addition, hot and cold treatment is often used in assembly.For example, when the bearing is assembled, the inner ring is often cooled in liquid nitrogen to shrink its size, while the outer ring is properly heated to enlarge its size, and then it is assembled together.The outer rim of a train wheel is also heated over a substrate, allowing it to be cooled to ensure its fastness (a method still used in some parts transfers).

    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 and so on.
