Metal processing machinery includes: automation machinery: automation tools, bearings, cleaning machines, mechanical drive systems, automatic control systems, packaging equipment, etc.; casting equipment: stamping equipment, lathes, milling machines, molding machines, Dressing machines, drilling machines, special purpose machinery, etc.; Metal cutting machinery: drilling, reaming, metal cutting, cutting tools, trimming, gear cutting, etc.; Surface treatment/forming: forming machinery, planing, painting systems, etc. . Material handling: cranes, transmission systems, lifts, elevators, warehouse equipment, heavy machinery equipment, etc.; Measuring equipment: precision measurement, optical measurement, testing machines, sensors, etc. Mechanical processing is a kind of processing machinery that uses processing machinery to measure the appearance, dimensions or performance of workpieces. The process of making changes. According to the temperature state of the workpiece being processed, it is divided into cold working and hot working. It is generally processed at room temperature and does not cause chemical or physical phase changes in the workpiece, which is called cold processing. Generally, processing at temperatures above or below normal temperatures will cause chemical or physical phase changes in the workpiece, which is called thermal processing. Cold working can be divided into cutting processing and pressure processing according to the difference in processing methods. Thermal processing commonly includes heat treatment, forging, casting and welding. Cold processing: turning (vertical lathe, horizontal lathe): the main feature is to process the rotary body; milling (vertical milling, horizontal milling): the main feature is to process the groove and the straight surface of the shape, and of course It can process curved surfaces with two or three axes. Planing: The main feature is to process straight-line surfaces. Generally, the surface roughness is not as high as that of a milling machine. Plugging: It can be understood as an upright planer, which is very suitable for non-complete arc processing. Grinding (surface grinding, cylindrical grinding, internal hole grinding, tool grinding, etc.) processing of high-precision surfaces. Drilling: the processing of holes, boring: the processing of holes with larger diameters and higher precision, and the processing of larger workpiece shapes.
