The main process of processing hardware parts

I. Requirements and steps for formulating process regulations

For the precision parts processing of hardware parts, the process regulations are technical documents guiding production, and the process regulations must be economically reasonable. The process regulations of a part refer to the processing methods and steps of the part. Content: Processing technology (heat treatment process), determine the machine tools, clamping methods, measurement methods, machining allowances, cutting parameters and time quotas used in each process. Filling in all the contents on a certain form of card, this is the regulation of mechanical processing technology, that is, the mechanical processing technology card.

Ii. Process analysis of Precision Parts Processing, the main contents are:

(1) The precision parts processing manufacturer tells you that check whether the drawings of the parts are complete and correct, and analyze whether the precision, completeness and technical requirements of the main surfaces of the parts can be met under the current production conditions.

(2) When processing hardware parts, check whether the selection of parts materials is appropriate and whether it will make the process difficult and complex.

​

Review the structural processability of the parts and check whether the structure of the parts can be processed economically and effectively.

The commonly used process documents are as follows.

(1) The mechanical processing technology process card for hardware parts processing, its main function is to briefly describe the mechanical processing technology route.

(2) Mechanical processing process cards: The process documents should be as detailed and complete as possible. Besides the process list, there should also be process cards for each process.
