Several Points To Note In The Processing Of Precision Mold Parts

1. Reasonable selection of equipment. The processing of precision mold parts is mainly to cut off most machining allowances, and high-precision mechanical parts are not required. Therefore, roughing should have greater power and high-precision machine tools. The completion process insists on using a relatively high-precision machine. Rough and finishing on different machines can give full play to the capabilities of the equipment and can extend its service life to precision machine tools.

2, in order to ensure the precision of precision mold parts processing, rough and fine mechanical parts processing from the best. Because when rough mechanical parts are processed, the cutting amount is large, and the cutting force, clamping force, heat, and mechanical parts of the workpiece have obvious work hardening.The workpiece has a large internal stress. If the workpiece is rough, the rough mechanical parts are completed. After continuous, part accuracy will soon be lost due to stress redistribution. For the machining of mechanical parts of some high-precision parts. After roughing and finishing, the low temperature annealing process should also be arranged or aging to eliminate internal stress.

3. In the processing route of precision mold parts, heat treatment is often arranged. The locations are arranged as follows: the heat treatment process to improve the cutting performance of the metal, such as annealing, normalizing, tempering, generally arranged in the machining of mechanical parts. Eliminate internal stresses, such as aging treatments, conditioning treatments, such as general layout drawings, after roughing, but after completion. In order to improve mechanical properties of components, such as carburizing quenching and tempering, generally arranged in the machining of mechanical parts.
