The requirement of precision parts processing _ precision parts processing factory

For high precision spare parts, processing is very harsh, machining process with the knife, the knife, etc. Have practical rules for size, precision and regulation, such as how much is 1 mm is negative microns, if wrong size too much will become a waste, this time is to have to again processing, time-consuming, and sometimes that would lead to all the processing of raw materials was, this leads to cost increase, in addition, the parts are there is no doubt that can not be used. For precision parts processing level is the key size of cylinder straight by how much money, for example, with strict management, are negative error within the prescribed scope is qualified parts, otherwise all don't pass parts; Width and actual strict management, is a negative error has requirements, such as an embedded columns ( Take very simple basic parts for example) Straight, if the is very big, beyond the range of allowable error, will cause, not in the condition of, if in fact the small, beyond the allowable error negative low limit, can lead to put down is very loose, the problem of unstable. This is all not pass goods, or the cylinder length is too long or too short, more than the allowable error scope, all don't pass the commodity, is must be abolished, or processing again, it will lead to cost increase. High precision parts processing rules, in fact, that is the most critical dimension problem, must strictly enforce more engineering drawings to carry out the processing, processing out actually size there is no doubt that it is not easy to the basic theory and engineering drawing the same size, just, if only within the scope of permissible error processing size are all qualified parts, therefore, the regulation of high precision parts processing is strictly carry out the basic theory size for processing. Second is excellent precision parts processing machinery, equipment and testing instruments, excellent production equipment prompt processing high precision parts at that time is more simple, higher precision and stronger practical effect. Testing instrument to test out the parts do not regulation, let all the goods sent to the customer's real do. Or so is of high precision parts processing are introduced in detail, looking forward to let you help. In order to ensure precision parts processing precision, coarse and fine mechanical parts processing separately from the best. Because when coarse machinery parts processing, cutting quantity is big, the artifacts by cutting force, clamping force, heat, and mechanical parts processing surface has the obvious work hardening phenomenon, artifacts within the larger internal stress, if rough, coarse machinery parts processing for continuous, after finishing the parts precision will soon lost because of the stress redistribution. Precision parts processing technology is developed in order to meet the need of modern high technology and advanced manufacturing technology, is based on the implementation of other high and new technology. It integrated application of the new achievement of the development of the mechanical technology and modern electronic, sensing technology, optics and computer and other high and new technology, is the basic technology in high-tech fields, in the national defense science and technology modernization plays a vital role in the construction of national economy, at the same time as the foundation of modern high-tech technology and an important part of driving the semiconductor technology, photoelectric technology, materials science and the cross development of many technologies such as progress. Machining accuracy reaches 1 micron mechanical processing method, precision parts processing is under the strict control of environmental conditions, the use of precision machine tools and precision measuring tool and measuring tool.
