1、 It is the main technical document to guide the production. The production planning and scheduling of the machining workshop, the operation of workers, the quality inspection of parts processing, and the accounting of processing cost are all based on the process procedures. To deal with the problems in production, the process specification is often taken as the common basis. If dealing with quality accidents, the responsibilities of relevant units and personnel shall be determined according to the process procedures.

2、 It is the main basis of production preparation. When the workshop wants to produce new parts, it should first formulate the machining process specification of the parts, and then make production preparation according to the process specification. For example: the analysis and research of the key process in the new parts processing technology. Prepare the required knives, clamps and measuring tools. Purchase or manufacture of raw materials and blanks. The purchase of new equipment or the modification of old equipment must be carried out according to the process.

Stainless steel material used in precision machining

1. The first is the requirement for the hardness of materials. For some occasions, the higher the hardness of materials, the better. It is only limited to the hardness requirements of processing parts. The processed materials should not be too hard. If they are harder than the parts, they cannot be processed.

2. Secondly, the material is moderate, at least one grade lower than the hardness of the parts. At the same time, it also depends on the function of the processed devices and the reasonable material selection of the parts. In short, there are still some requirements for materials in precision machining. Not all materials are suitable for machining. For example, if the materials are too soft or too hard, the former is unnecessary, while the latter is impossible.
