Parsing shenzhen precision parts processing what are the principles on the handle

More precision parts processing refers to the shape of workpiece size or through all kinds of mechanical properties to change process. Shenzhen machinery processing needed by the digital milling machine, digital display molding grinding machine, digital lathe, electric spark machine, universal grinding machine, machining center, laser welding, in silk, brisk walking wire, wire walking, cylindrical grinder, internal grinder, precision lathe, precision parts can be car, milling, planing, grinding and other processing, such machinery specialize in precision parts of cars, milling, planing, grinding, such as processing, processing can be all kinds of irregular shape parts, machining precision can be up to 2 microns. Shenzhen precision parts processing specific principles: ( 1) , in order to ensure accuracy of mechanical parts processing, coarse and fine mechanical parts processing separately from the best. Because when coarse machinery parts processing, cutting quantity is big, the artifacts by cutting force, clamping force, heat, and mechanical parts processing surface has the obvious work hardening phenomenon, artifacts within the larger internal stress, if rough, coarse machinery parts processing for continuous, after finishing the parts precision will soon lost because of the stress redistribution. For some high mechanical parts processing precision of parts. Before after rough machining and finish machining, also should be arranged or aging treatment of low temperature annealing process to eliminate internal stress. ( 2) And reasonable selection of equipment, coarse mechanical precision parts processing mainly cut off most of the machining allowance, does not require high precision machinery parts processing, so rough machining should be bigger in power and the high accuracy of machine tools, finishing process insist on using a high precision machine. Rough and finish machining on the machine in different, can give full play to the equipment capacity, and can prolong the service life of precision machine tools. ( 3) , in the mechanical precision parts processing craft route, often arrange the heat treatment process. Location arrangement is as follows: heat treatment process to improve the machinability of metals, such as annealing, normalizing, tempering, general arrangement before mechanical parts processing. Shenzhen machining to eliminate internal stress, such as aging treatment, conditioning treatment, general arrangement, after rough machining, but before finishing. In order to improve the mechanical properties of the parts, such as carburizing, quenching and tempering, general arrangement after mechanical parts processing. Such as heat treatment after large deformation, but also should arrange the final machining process.
