The production of nuts, studs and stainless steel is becoming more and more intelligent now. When producing the accessories of these equipment, we should choose accurate and high standard equipment. With the progress of science and technology, intelligent and automatic instruments and equipment have a very fast speed in the circulation of various fields, which brings challenges and opportunities to the development of precision parts in a new stage. Based on the analysis of the market demand and process concept of precision parts, combined with the skills and problems in the actual processing (limited to the scope of fitter operation), this paper discusses the solutions and skills of related problems in precision parts processing, so as to improve the quality of precision parts, improve the contradiction between market supply and demand, and promote the development of scientific and intelligent society.

In actual production, the structure of each part may be different, which greatly increases the difficulty of processing. But if we observe carefully, we can find that the basic geometric composition of the parts is nothing more than the outer circle, inner hole, plane, thread, tooth surface, curved surface and so on. So as long as we master the processing of these shapes, the difficulty of precision parts processing can be greatly reduced.

In the process of precision parts processing, the reasonable selection of positioning datum determines the quality of parts, and has a great influence on whether the dimensional accuracy and mutual position accuracy of parts can be guaranteed, as well as the processing sequence arrangement between the surfaces of parts. If the workpiece is installed with fixture, the selection of positioning datum will also affect the complexity of fixture structure. Therefore, the selection of positioning datum is a very important technological problem in precision parts processing.

Now in part of the production process has achieved mechanization, automation production, then the use of automatic processing system can automatically monitor its running state, in the external interference or internal incentive can automatically adjust its parameters, in order to achieve the best state and have the ability of self-organization, so as to ensure the processing accuracy under the premise of greatly improving the efficiency of rough and finish machining.
