precision parts processing industry standard is very strict, feed processing, different process working procedure such as a knife. Size will be according to the product have different specific requirements, the machining accuracy requirements will also be different, in general the accuracy requirement of the precision machining is very high, sometimes even how many microns difference under accurate to 1 mm, if the difference is very big size products will become a waste, rework is required to meet the requirements, the process is time-consuming, laborious can sometimes make all the raw materials of scrap, cause the increase of the cost, at the same time the parts also is not necessarily, so precision parts processing is there are a lot of requirements. So what's the requirement of precision parts processing? Below is the general manager Mr Xiao-gang xu answered:
( 1) Usually in order to ensure the parts machining precision, coarse parts and precision machinery parts processing must be run separately, because coarse parts processing and the amount of cutting precision parts processing, clamping force, calorific value, artifacts of cutting force is different, if continuous for rough machining and precision machining, precision machining parts precision will be lost because of the stress of different.
( 2) The rationality of equipment selection. Coarse parts processing to the requirement of machining accuracy is not high, is mainly for cutting machining allowance, so the precision requirement in very high precision machine tool processing.
( 3) In precision parts processing craft route, often arrange the heat treatment process. Location arrangement is as follows: heat treatment process to improve the machinability of metals, such as annealing, normalizing, tempering, general arrangement before mechanical parts processing.
( 3) Generally speaking precision parts processing, almost all have heat treatment process, heat treatment process can improve the machinability of the metal.
