Hardware parts processing

The main process of hardware parts processing
1、 Requirements and steps for developing process regulations
The precision machining of hardware parts, the process specification is a technical document that guides production, and the process specification must be economically reasonable. The process specification of a part is the processing method and steps of the part. Content: Processing technology (heat treatment process), determining the machine tool, clamping method, measurement method, machining allowance, cutting amount, and working hour quota used in each process. Fill in various contents on a certain form of card, which is the regulation of mechanical processing technology, that is, the mechanical processing technology card.
2、 The process analysis of precision parts processing mainly includes:
(1) The precision parts processing manufacturer tells you to check whether the drawings of the parts are complete and correct, and analyze whether the accuracy, completeness, and technical requirements of the main surface of the parts can be met under existing production conditions.
(2) Check whether the selection of material for hardware parts processing is appropriate and whether it will make the process difficult and complex.
Review the structural craftsmanship of the parts and check whether the structure of the parts can be economically and effectively processed.
3、 There are several commonly used process documents.
(1) The mechanical processing process card for hardware parts processing is mainly used to briefly explain the process route of mechanical processing.
(2) Mechanical processing process cards: Process documents are required to be as detailed and complete as possible, in addition to a process directory, there are also process cards for each process.
