Key points in the production process of precision parts processing

The precision part processing process is the basic unit that constitutes the machining process. The so-called process refers to the part of a process (or a group of workers) that is continuously completed on the same workpiece (or several workpieces at the same time) on one machine (or one working place). The main feature of forming a process is that it does not change the object, equipment and operator, and the content of the process is continuously completed.

The various shapes of precision part machining are composed of many surfaces in various combinations, with certain dimensions and mutual position requirements between the surfaces. A datum is a point, line, or surface on which a point, line, or face on a part (or part) is determined, that is, a datum is a face, line, or point on the part itself or related to the part, according to which A line or point to determine the location of other faces, lines, or points on the part.

In the process of manufacturing precision parts, due to different requirements of parts and production conditions, the manufacturing process of precision parts is different. When the same parts are produced by different process schemes, the production efficiency and economic benefits are also different. Under the premise of ensuring the quality of parts, the process of formulating a process plan with good comprehensive technical and economic benefits and reasonable and feasible process is called process design of precision parts processing. The cutting process for precision part machining consists of a number of processes, each consisting of a station, a step, a pass and an installation.
