In the past, due to the backwardness of precision parts processing technology and equipment in China, it was impossible to process precision parts with small caliber, high precision and complex surface shape, which seriously affected the technical progress in relevant fields in China. For precision parts, the processing is very strict, and the processing procedures include knife feeding, knife discharging, etc.
There are specific requirements for size and precision, such as the number of plus or minus micrometers of 1mm. If the size is too wrong, it will become a waste product. At this time, it is equivalent to having to re process, time-consuming and laborious, and sometimes even the entire processing material will be scrapped, which leads to increased costs. At the same time, the parts are definitely useless. Precision parts processing is a very important technology for the machine industry, because in many cases such a good technology is needed to better strengthen production.
The role of precision machining is small. Precision machining varies from one digit to three digits. It is processed by simple mold, soft mold, or directly. The processing of Dalian precision parts is generally the usual mechanical processing process of turning, milling, planing, grinding, pliers, etc., as well as the cutting, drawing, drilling, tapping, etc. of fitters.
Representative industries include aviation, aerospace industry, shipbuilding industry, construction machinery industry, machine tool industry, etc. The role of precision machining is to focus on small precision machining, which can largely meet more personalized product customization. The progress of social civilization and the improvement of people's daily living standards have gradually surfaced in the pursuit of personalized materials.
