1. Reasonably select the equipment. The processing of precision mold accessories mainly cuts out most mechanical processing waste, and does not require high precision mechanical parts. Therefore, rough machining should have greater power and high -precision machine tools. The completion process insists on using a relatively high precision machine. Rough and precise processing can give full play to the equipment capabilities on different machines, which can extend its service life precision machine tool.
2. In order to ensure the processing accuracy of precision mold accessories, the processing of coarse and fine mechanical parts is the best. Because when the rough mechanical parts are processing, the amount of cutting is large, the cutting force, clamping force, thermal, and mechanical parts of the mechanical parts of the workpiece have obvious processing hardening. In the subsequent continuous, the accuracy of the parts will soon lose due to stress. Processing of mechanical parts of some high -precision parts. After rough processing and precision processing, the low temperature annealing process should also be arranged or aging to eliminate internal stress.
3. In the processing process of precision mold accessories, the heat treatment process is often arranged. The location arrangement is as follows: the heat treatment process, and the metal that improves its cutting process, such as annealing, fire, fire, and general arrangement in mechanical parts processing. Eliminate internal stress, such as timely treatment, adjustment treatment, such as the general layout diagram, after the rough processing, but completion. In order to improve mechanical performance components, such as carburizing quenching and ignition, it is generally arranged in mechanical parts processing.
