1.In order to ensure Precision Machining accuracy, coarse and fine processing should be carried out separately. If the coarse and fine processing machining is continuous, fine machining Precision Machined Parts accuracy will be lose quickly due to the re distribution of stress. For some parts with high processing precision, before and after rough processing, low temperature annealing or aging treatment should be arranged to eliminate internal stress.
2.Reasonable selection of equipment. Rough machining should be carried out on machine tools with large power and low accuracy. Fine machining requires higher accuracy machine tools. Reasonable equipment can not only give full play to equipment capacity, but also prolong the service life of precision machine tools.
3.Heat treatment process is often arranged in the machining process.
