Precision parts processing enterprises technological process is how to make?
As an enterprise engaged in precision parts
processing for 16 years, our parts processing process are carried out in strict accordance with the process file, process staff will machining
process is finished, need to fill in a certain format of the content of the process file CARDS.
Commonly used process file format has the following kinds: one is precision machinery processing craft process card, the card is relatively simple, description of every working procedure is not specific, so generally does not directly guide operation for worker, but is often used as a production management, it was based on the process of the unit, the whole precision metal processing is briefly lists the process routes, including blank manufacturing, machining, heat treatment, etc. , it is the basis for the preparation of other process documentation, and production preparation, the main basis of planning and organizing production.
Suitable for sheet small batch production.
The other is a machining process CARDS, process in detail for the unit to the entire process, including parts of the material, weight, name of blank type, procedure, process, process parameters and use of equipment.
It is used to help management staff and technical precision parts processing process and guide the workers operation, widely used in the batch of parts or small batch production of the important parts.
Formulating procedure steps: first is the development of technical process of preparation of raw materials: 1.
Product drawings, assembly drawing, part drawing, the quality of the product acceptance criteria, blank data, etc. ;
Product parts process route table or workshop schedule of division of labor, to understand the status of the product and the management of the enterprise;
Clear production platform, determine the type of manufacture.
Next to precision metal processing technology, including the selection of locating datum, the determination of the surface processing methods, processing stages division, the determination of the concentration and dispersion degree of process machining sequence of reasonable arrangement, etc.
Finally determine the machining allowance of each process, calculating the dimension and tolerance, selection of equipment and process equipment, determine the cutting parameter and the calculation of time quota, fill out the process documents.
To guarantee for process planning is feasible, must be familiar with the production condition of this enterprise, such as production capacity of blank, special equipment and process equipment manufacturing capacity, technical level of workers, etc.
Also familiar with the process standards, equipment and process equipment and materials, familiar with enterprise's various standards and industry standards, actively introduce advanced technology to improve the level of technology.
