How to determine the precision gear? What are SC's gear machining capabilities?

Precision gears, also known as silent gears, and the gear surface grinding-grade must be above JIS2 (or DIN6).
After the tooth surface there has been heat treatment hardening such as carburizing or high frequency, although the strength of the tooth surface is improved.
However, due to the high temperature quenching, the tooth accuracy is also reduced, which will increase the noise and shorten the service life. After grinding the tooth surface, high-strength and high-accuracy precision gears can be obtained.
Shiuh Cheng's world-class equipment can not only precisely process ultra-precision tooth surfaces of gears but also perform complex and diverse tooth profile changes and various tooth profile corrections using special processing technologies.
