What are the options for high-precision CNC machining positioning datums? The production of nuts, studs, and stainless steel is becoming more and more intelligent. When producing accessories for these equipment, choose accurate and high-standard equipment. With the advancement of science and technology, intelligent and automated instruments , The circulation of equipment in various fields has a very fast speed, which brings new challenges and opportunities to the development of precision parts. In this paper, by analyzing the market demand and process concept of precision parts, combined with the skills and problems in actual processing (limited to the scope of clamp work), this paper discusses the solutions and skills of related problems in high-precision cnc processing, so as to improve high-precision machining. The quality of precision CNC machining improves the contradiction between market supply and demand, and promotes the development of a technological and intelligent society.

In actual production, the structure of each part may be very different, which greatly increases the difficulty of processing. But if you observe carefully, you can find that the basic geometric composition of the parts is nothing more than an outer circle, an inner hole, a plane, a thread, a tooth surface, a curved surface, etc., so as long as you master the processing of these shapes, the difficulty of high-precision CNC machining can also be significantly reduced.

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

Now, mechanized and automated production has been achieved in some of the production processes, so the use of automated processing systems can automatically monitor its operating status, and automatically adjust its parameters when subjected to external disturbances or internal incentives to achieve the best state. Self-organizing ability, thus greatly improving the roughing and finishing efficiency on the premise of ensuring the machining accuracy.
