Accuracy design function module program accuracy design is reasonable, will directly affect the quality, service life and economic benefits of mechanical products. Therefore, it is an important part of mechanical product design. The principle of precision design is to make the manufacturing cost of the product as low as possible and the economic benefit is good under the premise of ensuring the excellent performance of the product. The content of precision design is mainly contained in three aspects: dimensional accuracy design, shape and position precision design and surface roughness design. The content of these three aspects is not isolated but related. There are three principles of relationship between the shape and position tolerances of the part and the dimensional tolerances, namely the principle of independence, the principle of containment and the principle of maximum entity. Different work performance and different principles. Different dimensional tolerances and geometric tolerances of the part require different surface roughness. The different mating properties between the parts will also result in different geometric tolerances, dimensional tolerances and surface roughness requirements. When working with standard parts (such as bearings), precision design should be carried out according to the requirements of standard parts. Copper nuts made of all kinds of embossed wire (usually lead brass, such as H59, 3604, 3602). Our daily contact with the embedded knurled copper nuts are processed by precision automatic lathes. The reference standard of embedded knurled copper nut comes from GB/T809, but the technical parameters of all kinds of embedded nuts produced by our company exceed the relevant indexes required by the national standard.
