Precision parts processing process

First, the requirements and steps for formulating the process specification

Precision parts processing, the process specification is the technical document to guide the production, the process specification must be economical and reasonable. The process specification of the part is the processing method and steps of the part. Contents: Processing technology (heat treatment process), determine the machine tool, clamping method, measurement method, machining allowance, cutting dosage and working hour quota used in each process. Fill in the various contents on a certain form of card, this is the specification of the machining process, that is, the machining process card.

Second, the process analysis of precision parts processing, its main contents are:

(1) Precision parts processing manufacturers tell you to check whether the drawings of the parts are complete and correct, and analyze whether the accuracy, integrity, and technical requirements of the main parts can be met under the existing production conditions.

(2) Check whether the selection of parts materials is appropriate and whether it will make the process difficult and complex.

Examine the structural workmanship of the part and check whether the part structure can be processed economically and effectively.

Third, the commonly used process documents include the following.

(1) Machining process card, its main function is to briefly describe the machining process route.

(2) Machining process cards: require the process documents to be as detailed and complete as possible, in addition to the process catalog, there are also process cards for each process.
