Nowadays, the technology in the fields of machine tool processing, tool production and processing, and manufacturing has continued to improve. In recent years, you can understand from the news reports concerned about these aspects. The total number of people in the manufacturing field can be said to have improved very high every year, but not all The spare parts of the company are all made in China. If the industrial equipment is stronger and the quality is more assured, it will also select export spare parts, export spare parts, parts, special tools, and have to be recognized, and the actual effect will be better.
The problem of differences in the processing of precision mechanical parts cannot occur. The standard tolerance is required by the national standard to clarify any dimensional tolerance of the tolerance level size. Tolerance grades define the precise level of dimensions. The national standard divides dimensional tolerances into 20 grades, which are respectively indicated by IT01, IT0, IT1~IT18, which are called standard tolerances. IT (International Tolerance) indicates standard tolerances. Timing, the higher the tolerance level and the smaller the standard tolerance value, the higher the dimensional accuracy. Basically holes and shafts of the same size and tolerance class have the same standard tolerances. For better convenience, the national standard divides the basic size category of ≤500 into 13 size segments.
Product standardization itself includes three levels of meaning: (1) Generalization of product types, specifications and models—the basic parameters, forms, sizes, and basic structures of the same type of products are successively filed to make generalized products, with partial A small number of types, specifications and models meet the general needs of customers; (2) Integration of precision machinery parts - the same type of products of the same type or different types of products with the same main purpose and structure (such as anchor bolts, bearing with seat, connecting (3) Product safety standardization - product quality is the "fate line" of any company. To ensure product quality is up to standard and stable, it is necessary to do a good job in design and production process , installation and testing, and even the standardization of packaging, storage and transportation. Only in this way can we gain a firm foothold in the fierce market demand.
