Precision parts hardware processing to comply with what requirements?

The first is the size of the requirements, must strictly follow the drawing of the form and position tolerance requirements for processing. Although the parts produced by processing will not be exactly the same as the size of the drawings in fact, the Anji size is within the tolerance range of the theoretical size, and it is a qualified product that can be used. Secondly, the requirements of equipment, rough and finish processing should be carried out using different equipment. Since the roughing process is to cut most of the parts of the wool, the workpiece will produce a lot of internal stress in the case of large feed and large cutting depth, at this time, it can no longer be finished. When the workpiece is finished after a certain time, it should be worked on a high-precision machine tool, so that the workpiece can achieve high accuracy. Once again, the processing of fine parts often has surface treatment and heat treatment processes, surface treatment should be placed after precision machining, and in the process of precision machining, it should be considered to leave the yellow after surface treatment. The thickness. Heat treatment is to improve the cutting properties of the metal, so it needs to be carried out before machining.

The precision machining industry has always been labor-intensive, capital-intensive and technology-intensive industries, and the industry threshold is high, and the general enterprises are difficult to generate profits even if they do not reach a certain scale. Its requirements for precision machining are extremely strict. The process of precision parts processing has extremely strict requirements, and a slight mistake in processing will lead to the error of the workpiece beyond the tolerance range, and it will need to be re-processed, or announced that the gross bad scrap will greatly increase the cost of production.
