【正文】 ss control Mold parts processing, a general guiding principle is for different materials, different shapes, different technical requirements for adaptive processing, it has a certain degree of plasticity through the control of processing to achieve good machining results. According to the appearance of the shape of different parts, the parts can be broadly classified into three types: shaft, sheet metal and shaped parts, the mon process along the lines of: roughing heat treatment (quenching, quenching and tempering) Grinding Xinhua processing fitter (Surface Treatment) group with processing. parts of heat treatment Parts of the heat treatment process, in the hardness of parts was required, the need to control the internal stress to ensure that the size of parts processing stability, respectively, of different materials have different approach. Some corner of the production of more plex shape of the workpiece, is also not sufficient to eliminate the quenching tempering stress, needs to be carried out before finishing annealing to stress or multipleaging treatment, the full release of stress. For V10, APS23 parts such as alloy steel powder, which can withstand hightemperature tempering, hardening time secondary hardening process can be ,10501080 ℃ quenching, and then 490520 ℃ and a number of hightemperature tempering to obtain a more high impact toughness and stability, on the edge of collapse as the main form of failure is very applicable to die. High cost of alloy steel powder, but its performance is being widely used to form a trend. grinding parts Grinding machine used there are three main types: surface grinding machine, internal and external circular grinding machine and abrasive
