Hardware parts processing manufacturers explain what is ultra-precision processing

According to hardware parts processing manufacturers, processing with a precision of less than 3 μm is usually referred to as ordinary precision, and processing with a higher than this value is called ultra-precision processing.

In the category of high-precision trainers, there are three grades according to the level of accuracy:

The accuracy is 3~O. 3 μm, the roughness is O. 3~O·03μm is called precision machining;

The precision is 0.3 ~ 0.03 μm, the roughness is 0.03 ~ 0.005 μm, it is called ultra-precision machining, or sub-micron machining;

The precision is 0.03 μm (30 nanometers), and the roughness is better than 0.005 μm or more, it is called nanometer (nm) processing.

According to the analysis of hardware parts processing manufacturers, the processing accuracy of precision molds is generally only a few microns, and its fineness is 1% of a human hair. Take the flatness of mold manufacturing as an example. The industry standard requires that the flatness of the mold should be 10% of the material thickness, and the precision can be 8%; the industry standard for machining accuracy is plus or minus 0.01 mm, and the precision can be plus or minus 0.003 mm. , Which is 3 microns. It has been relatively successful in ultra-precision machining.

What are the shortcomings and shortcomings of ultra-precision processing technology?

According to hardware parts processing manufacturers, defects are mainly related to processing efficiency and accuracy. The more precise the equipment, the lower the efficiency. This is normal, and the accuracy is related to the operation and technical level. Many equipments are foreign Imported, so the maintenance cost of the equipment is very high.
