Elements to be noted in the processing of precision mold accessories:
1、 Reasonably select equipment. Rough machining of mechanical parts mainly involves cutting off most of the machining allowance and does not require high-precision machining of mechanical parts. Therefore, rough machining should have greater power and high-precision machine tools, and a relatively high precision machine should be used to complete the process. Rough and precision machining on different machines can fully utilize equipment capabilities and extend the service life of precision machine tools.
2、 In order to ensure the machining accuracy of precision mold parts, the processing of coarse and fine mechanical parts is carried out separately from the best. Because when processing rough mechanical parts, the cutting amount is large, and the cutting force, clamping force, heat, and surface of the mechanical parts have obvious work hardening phenomena, the workpiece is subjected to high internal stress. If the rough mechanical parts are continuous after processing, the accuracy of the parts will quickly lose due to stress redistribution. For the machining of some high-precision mechanical components. After rough and fine machining, a low-temperature annealing process should also be arranged or aged to eliminate internal stress.
3、 In the process route of precision mold parts processing, heat treatment processes are often arranged. The location arrangement is as follows: during the heat treatment process, metals that improve their cutting performance, such as annealing, normalizing, tempering, are generally arranged for mechanical parts processing. Eliminating internal stress, such as time treatment, adjusting treatment, such as overall layout, rough machining, but after completion. In order to improve the mechanical performance of components, such as carburizing, quenching, and tempering, they are generally arranged in the machining of mechanical parts. If there is significant deformation after heat treatment, the final machining process must also be arranged.
