Precision parts processing industry standards are very strict, processing when there are different process procedures such as into the knife, out of the knife. Size will also have different specific needs according to the product, processing accuracy requirements will also be different, in general, precision machining accuracy requirements are very high, sometimes even accurate to 1mm under the number of microns difference, size if the difference is very large products will become scrap, it is necessary to rework to meet the requirements, this process is very time-consuming and labor-intensive, sometimes making all the raw materials scrap, resulting in increased costs, and at the same time the parts are bound to be unusable. At the same time parts are also bound to be unusable, so precision parts processing is a lot of requirements. So what are the requirements of precision parts processing?
(1) usually in order to ensure the machining accuracy of the parts, coarse parts and precision mechanical parts processing must be run separately, because coarse parts processing and precision parts processing cutting volume, clamping force, heat, the workpiece is subjected to cutting force are not the same, if rough machining and precision machining continuous, precision machining parts precision will be lost because of the difference in stress.
(2) the reasonableness of the choice of equipment. The processing of rough parts does not require high machining accuracy, just mainly for machining margin cutting, so precision machining requires processing in very high precision machine tools.
(3) in the precision parts processing process route, often arranged with heat treatment process. Heat treatment process location is arranged as follows: in order to improve the cutting performance of the metal, such as annealing, normalizing, tempering, etc., generally arranged in mechanical parts before processing.
(4) Generally speaking, precision parts processing almost all have heat treatment process, heat treatment process can improve the cutting performance of the metal
