The part machining process is a process that directly changes the appearance (shape, size, location, performance) of the raw material to make it a semi-finished product or finished product. This process is called the process flow, which is the reference of the processing technology of the part. The process flow of precision parts processing is more complicated. The following is the technical reference for precision parts processing.
The benchmarks for precision parts processing can be divided into different categories according to different processes: casting, forging, stamping, welding, heat treatment, machining, assembly, and so on. The process of precision parts processing generally refers to the general term of the entire part of the NC machining and machine assembly process, and other such as cleaning, inspection, equipment maintenance, oil seals, etc. are just auxiliary process Bale. The turning method changes the surface properties of raw materials or semi-finished products. This process is called the NC machining process. The CNC machining process is the most important process in the precision parts processing industry.
Process reference for precision parts processing
The following describes in detail the process standard of CNC precision parts processing
(1) Positioning reference, the positioning reference used by the lathe or fixture when machining on a CNC lathe.
(2) A measurement reference, which usually refers to the size or location criteria that must be observed during the inspection.
(3)Assembling criteria, which we usually refer to when the assembly process
