nd fixed in the form of documents and standards to form a process document.

The process documents can be divided into two types: one is a comprehensive process document, that is, all the requirements of a product are compiled in a single file, which is simple and clear, easy to query, and suitable for occasions with simple product structures and small production batches.

The second is the type of process documents, that is, the classification is based on the professional characteristics of product manufacturing technology, highlighting the professional characteristics, applicable to all types of products.　　

Rolling bearings as a standardized mechanical parts and components, except for individual varieties, the production process of most varieties is basically similar. Therefore, the compilation of manufacturing process documents for SKF bearing parts is convenient for standardization and serialization.　　

1. Types of process documents　　

Bearing parts manufacturing process documents can generally be divided into three categories: dominant process documents, management process documents and production process documents.

The dominant process is the foundation, the management process file is used to supply and manage the materials needed in the part manufacturing process, and the production process file is used to guide production.　　

2. Basis for preparation of process documents　　

Mainly include: product design drawings, national standards, enterprise standards, internal standards and regulations related to products, special requirements put forward by customers, process equipment, technology and management level possessed by the enterprise, production scale and production layout, etc.　　

3. Features of the process documents　　

(1) Mandatory process documents are important regulations to ensure product quality, ensure the orderly production and carry out enterprise management. Once issued, they must be resolutely implemented.
