The cooperation and operation of machine parts are absolutely indispensable for the normal operation of machinery. If the machine parts do not meet the performance requirements of the mechanical equipment, it may cause the mechanical equipment to fail to achieve good working results or even fail to work. Then the following are some requirements of different machines for machine parts.

Its requirements for the stability of the fit are very high. It is required that the wear limit of the parts does not exceed 10% of the dimensional tolerance value of the parts during use or after many times assembly. This is mainly used in precision instruments, meters, and precision measuring tools. 

The production of precision parts is firstly based on dimensional requirements and must be processed in strict accordance with the shape and position tolerance requirements of the drawings. Although the dimensions of generally processed parts are not exactly the same as the dimensions of the drawings, the actual dimensions are within the tolerance range of the theoretical dimensions, and they are all qualified products.

Secondly, rough and fine processing should be carried out with the equipment of different performance. Since the rough machining process is to cut most parts of the blank, a large amount of internal stress will be generated on the workpiece when the feed rate is large and the cutting depth is large, and the finishing process cannot be performed at this time. When the workpiece is subjected to the finishing process after a certain period of time, it should be worked on a higher precision machine tool, so that the workpiece can achieve high precision.

The processing of precision parts often involves surface treatment and heat treatment, and the surface treatment should be placed after precision machining. And in the process of precision machining, the thickness of the thin layer after surface treatment should be considered. Heat treatment is to improve the cutting performance of the metal, so it needs to be carried out before the machine tool processing.

This has high requirements for the stability of the fit. It requires that the wear limit of the parts does not exceed 25% of the dimensional tolerance value of the parts, and it requires a well-closed contact surface. It is mainly used in machine tools, and surfaces that cooperate with rolling bearings and contact surfaces with relatively high moving speeds, such as the mating surfaces of sliding bearings, gear teeth working surfaces, etc.

It is required that the wear limit of mechanical parts does not exceed 50% of the dimensional tolerance value and the contact surfaces of parts without relative movements, such as box covers and sleeves. And it requires close contact surfaces, working surfaces of keys and keyways, and contact surfaces with low relative motion speeds, such as bracket holes, bushings, working surfaces of pulley shaft holes, reducers, and so on.

Machine parts must be designed and produced strictly in accordance with the specific requirements of the applied machinery and equipment, and the design error must be minimized in order to achieve a better operational effect.
