A gear grinder can be used to grind high-speed cylindrical gears with multiple teeth and a small module on the tooth surface to ensure jis0 or higher tooth accuracy. As a result, even when the circumferential speed is 100 m / s or higher, smooth and quiet engagement can be achieved, so it is used in compressors and generators that require a large number of high-speed rotations.

Gears with helical gears with different torsional directions processed at two positions of the same shaft are called double helical gears. The tooth surface is polished with a gear grinder, which is used for rotating equipment that needs high-speed rotation. Due to its coaxial left-right distortion, it offsets the generated thrust, which is a favorable gear for design and use.
