The general process of SKF production of rolling bearing
The composition of rolling bearing outer ring, inner ring, the parts of a rolling body and a holding frame. For different parts, the machining process and method is different. For the same kind of parts, if its structure, different levels of precision, the process and methods are also different. At present, the production process in a SKF bearing small ordinary precision is roughly the same as in Table 2 and 1 shows.
Process documents
The content of the induction process is a form of written documents, process documents, i.e. the process rules. General guide workers to operate and various techniques for the production of documents, process management belong to the category of process files. Many process file types, different products and production type, the format and level of detail are also different, in the bearing industry, process file includes two categories: the leading file and directly serve production document.
The dominant files: blank map: there are various parts of the blank graphic structure, size tolerance standards, the total surface machining allowance standard and processing method. Table 2 - 2 to table 2 - 4 is a bearing ring forging factory allowance and tolerance standard. Inspection specification: includes the inspection object, inspection items, should be used to check the quantity, inspection method and inspection of tool and gauge etc..
