General technological process of rolling bearing production

Scroll of general technological process of rolling bearings SKF bearing production parts are outer ring, inner ring, rolling element and cage. For different parts, the processing process and methods are different. For the same kind of parts, if its structure, precision grade is different, its processing process and methods also have differences. At present, small and medium-sized general precision grades of the production process of SKF bearing is roughly same, such as table 2 - 1. Process documentation to process the content of induction, in the form of written documents is a kind of process documents, process planning. General to guide operation for worker and used for production, process management, and other various technical documents are belong to the category of process files. Process documentation is a lot of more phyletic, the different types of products and production, the format and general degree is different also, in the bearing industry, process documents include two categories: dominant and direct service production file. Main file are: blank drawing: there are various components of the blank graph, structure size tolerance, the surface machining allowance standard and processing methods. Table 2 - 2 - table 2 - 4 is a bearing factory of ring forging allowance and tolerance standards. Inspection specification: object contains the content of the check, inspection items, check the number, inspection methods and the use of tools and measuring tool, etc.
