???? Manufacturing tolerance has always been the goal people have pursued, and now it is clear that it has become a reality. Advanced CNC machine tools have high-precision bearings and guides, which can be easily accurate to one hundredth of a millimeter. Many standards in machinery manufacturing today require manufacturing tolerances of less than one thousandth of a millimeter.
Nowadays, it is difficult for conventional machining processes to meet the existing product requirements. For example, in today's gear processing, it is very common for gears to be ground and then measured by high-precision testing machines. Low noise, reduced energy consumption and higher lifespan are the effects everyone hopes to obtain.
