Introduction to machining concept
Machining is the process of changing the dimensions or properties of a workpiece with a processing machine. According to the temperature state of the workpiece being processed, it is divided into cold working and hot working. Generally processed at room temperature, and does not cause chemical or physical phase changes of the workpiece, called cold processing. Generally, processing at a temperature higher or lower than the normal temperature causes a chemical or physical phase change of the workpiece, which is called thermal processing. Cold machining can be divided into machining and pressure machining according to the difference in processing methods. Thermal processing is commonly used for heat treatment, forging, casting and welding.
In addition, cold heat treatment is often used in assembly. For example, when the bearing is assembled, the inner ring is cooled in liquid nitrogen to shrink its size, and the outer ring is appropriately heated to enlarge the size, and then assembled together. The outer ring of the train's wheel is also heated on the base body to ensure the tightness of the joint when cooling (this method is still used in the assembly process of some parts).
Machining includes: filament power windings, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, precision welding, etc.
Machining: Generalized machining refers to the process of manufacturing products by mechanical means; in the narrow sense, Lathe Machine, Milling Machine, Dringing Machine, Grinding Machine, Stamping Machine, Die Casting The process of making parts by special mechanical equipment such as machine.
Impeller normally applied in the centrifugal pumps.
Impeller is a rotating component equipped in the Pump Housing, help to transfer to energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation.
