Manufacturing technology of rolling bearing parts

The process documents are formed by fixing the contents and requirements of the manufacturing process according to certain procedures and fixing them in the form of documents and standards. Process documents can be divided into two types: one is comprehensive process documents, which means that all requirements of a product are compiled in one document, which is simple and clear, easy to query, and suitable for the occasions with simple product structure and small production volume. Second, the process documents of different types, that is, classified and compiled according to the professional characteristics of product manufacturing technology, highlighting the professional characteristics, and applicable to various products.

As a kind of standardized mechanical parts, rolling bearing has similar production process of most varieties except for individual varieties. Therefore, the preparation of manufacturing process documents of bearing parts is convenient to realize standardization and serialization.

1. types of process documents

The manufacturing process documents of bearing parts can be divided into three types: leading process documents, management process documents and production process documents. The leading process is the basis, and the management process documents are used to supply and manage the materials needed in the manufacturing process of parts, and the production process documents are used to guide the production.

2. basis for preparation of process documents

It mainly includes: design drawings of products, national standards, enterprise standards, internal standards and regulations related to products, special requirements put forward by customers, technological equipment, technology and management level, production scale and production level of the enterprise

Production layout, etc.

3. characteristics of process documents

(1) The directive process documents are important regulations to ensure the quality of products, to ensure the orderly production and to carry out enterprise management. Once issued, they must be firmly implemented.

(2) Basic process documents are the basis of production organization, material supply, quality management and economic accounting of enterprises, and basic documents for each business department of the enterprise to carry out work.

(3) The operational process documents not only require accuracy, completeness, unification and specification, but also are easy to understand and simple, and suitable for common operation. Therefore, it is necessary to have a strong operability in practical work.

(4) The enterprise image process document is formulated according to the actual situation of the enterprise. Its content focuses on the advantages of the enterprise in technology, management and process equipment, and reflects the strength and image of the enterprise in one aspect.
