What should we pay attention to when processing precision mold parts?


In order to ensure the quality of precision mold parts processing products, there are many matters need to pay attention to, so what to pay attention to when processing precision mold parts? The following article for us to reveal.
What to pay attention to when processing precision mold parts
① in order to ensure precision parts processing accuracy, coarse and fine mechanical parts processing is best to be carried out separately. Because rough mechanical parts processing, cutting volume, the workpiece is subject to cutting force, clamping force, more heat, as well as mechanical parts processing surface has a more significant machining hardening phenomenon, the workpiece exists inside a large internal stress, if rough, rough mechanical parts processing continuously, the precision of the parts after finishing will be quickly lost because of the redistribution of stress.
② reasonable choice of equipment. Coarse mechanical parts processing is mainly cut off most of the machining allowance, and does not require a high precision mechanical parts processing, so rough machining should be carried out in the power, accuracy is not too high machine tools, finishing processes require a higher precision machine tools processing.
③ in the precision parts processing process route, often arranged with heat treatment process. Heat treatment process location arrangements are as follows: to improve the cutting performance of the metal, such as annealing, normalizing, tempering, etc., generally arranged in mechanical parts before processing.
In the premise of precision mold parts processing to ensure quality, according to the specific conditions of production, try to improve production efficiency and reduce production costs, to develop a reasonable processing technology. In order to improve the production efficiency of precision mold parts processing, first of all, the parts to be processed must be carefully analyzed to find out the material of the parts, structural characteristics and shape tolerance requirements, roughness, heat treatment and other aspects of technical requirements. Then on this basis, choose a reasonable processing process and route.
