Analysis of the finishing mold control 1, Introduction Mold is a large group with the parts from, the quality of parts with a direct impact on the quality of mold, and the final parts to plete the finishing quality assurance in turn, so that control is crucial to finishing. Most of the mold in the domestic manufacturing enterprises, finishing stage of the method used is generally grinding, EDM and fitter to deal with. At this stage to control the good parts deformation, internal stress, shape and size of precision tolerances and many other technical parameters, in the specific production practice, the operation more difficult, but there are still many effective methods of experience is worth learning from. 2, die finishing process 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 temp
