Main process of hardware parts processing
1. Requirements and steps for formulating process specifications
For precision parts processing of hardware parts processing, process specifications are technical documents to guide production, and process specifications must be economical and reasonable. The process specifications of parts are the processing methods and steps of parts. Content: Processing technology (heat treatment process), determine the machine tools, clamping methods, measurement methods, processing allowances, cutting amounts and working hours used in each process. Fill in the contents on a card of a certain form, which is the specification of mechanical processing technology, that is, the mechanical processing process card.
2. Process analysis of precision parts processing, its main contents are
(1) Precision parts processing manufacturers tell you to check whether the drawings of parts are complete and correct, and analyze whether the accuracy, surface integrity, technical requirements, etc. of the main surfaces of the parts can be achieved under the existing production conditions.
(2) Hardware parts processing checks whether the selection of parts materials is appropriate and whether it will make the process difficult and complicated.
Review the structural processability of parts and check whether the part structure can be processed economically and effectively.
3. Commonly used process documents are as follows.
(1) The main function of the machining process card for hardware parts processing is to briefly describe the machining process route.
(2) The machining process card requires 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.
