Select high cost performance precision parts for processing

November 3, 2022

The processing of precision parts is mainly about size requirements, such as the cylinder diameter. There are strict requirements. Only qualified parts with positive and negative errors within the specified requirements, otherwise they are unqualified parts; There are also specific and strict requirements for length, width and height, and there are also provisions for positive and negative errors. For example, if the diameter of an embedded cylinder (take the simplest basic components as an example) is too large and exceeds the allowable range of errors, it will result in failure to insert. If the actual diameter is too small and exceeds the lower limit of allowable negative values of errors, it will result in too loose and unstable insertion. For precision parts, the processing is very strict, and the processing procedures include knife feeding, knife discharging, etc.

Precision parts processing has specific requirements for size, and precision of precision parts processing also has requirements, such as 1mm plus or minus micrometers. If the size is too much 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 an increase in cost. At the same time, the parts are definitely useless.

With the comprehensive deepening of reform and opening up, we have gone through 35 years, and the competition in China's hardware parts market has become increasingly fierce. Many foreign companies continue to enter China's market and take root in China, making use of China's cheap labor to produce their brand products for higher profits.


Our own enterprises have been greatly suppressed and excluded. At present, the advanced hardware parts in the world are facing technological breakthroughs, big or small. If China's hardware parts can seize this great opportunity, give play to their advantages, and develop some competitive products with international competitiveness, it is also possible.
