Many people know what precision parts processing is, but for machining technology, I think there are still many people who are not very familiar with it. The machining process specification is one of the process documents that stipulate the machining process and operation method of parts.

Under specific production conditions, the more reasonable process and operation method are written into the process document in the prescribed form, which is used to guide the production after being approved. Machining process specification generally includes the following contents: process route of workpiece processing, the specific content of each process and equipment and process equipment used, inspection items and inspection methods of the workpiece, cutting amount, time quota, etc.

Precision parts processing technology is based on the process to change the shape, size, relative position and nature of the production object to make it a finished product or semi-finished product. It is a detailed description of each process. For example, as mentioned above, rough machining may include blank making, grinding, etc., and finishing may be divided into turning, fitter, milling machine, etc., and each step is required There are detailed data, such as how much roughness to achieve, how much tolerance to achieve.

According to the number of products, equipment conditions and the quality of workers, technicians determine the technological process to be adopted and write the relevant contents into process documents, which are called process procedures. This is more targeted. Every factory may be different because the actual situation is different.

Generally speaking, the process flow is the program, the processing technology is the detailed parameters of each step, and the process specification is a specific processing technology compiled by a certain factory according to the actual situation.
