Many people know what precision parts processing, but for the machining process, presumably many people 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. It is a process document which is written in the specified form according to the more reasonable process and operation method under the specific production conditions, and is used to guide production after approval. Machining process specification generally includes the following contents: process route of workpiece processing, specific contents of each process, equipment and process equipment used, inspection items and methods of workpiece, cutting amount, time quota, etc.
Precision parts processing technology is to change the shape, size, relative position and nature of the production object on the basis of the process to make it a finished or semi-finished product. It is a detailed description of each process. For example, as mentioned above, rough machining may include rough manufacturing, grinding, etc., and finish machining may be divided into turning, fitter, milling machine, etc., each step is necessary There are detailed data, such as how much roughness to achieve, how much tolerance to achieve.
According to the quantity of products, equipment conditions and quality of workers, technicians determine the adopted process 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 parameter of each step, and the process procedure is a specific processing technology compiled by a factory according to the actual situation.
