強制駆動方式を採用しているので設備費は高かった。2. Description of the Related Art Conventionally, in order to efficiently finish a tooth surface after quenching a gear, a WA-based grindstone or superabrasive (diamond, CBN
Etc.) There are various tooth profile grinding methods using a grindstone, and the grindstone shapes used include an external gear type, an internal gear type, and a worm type. Most of the tooth profile grinding machines for these purposes are single-purpose machines using external gear type tools. Therefore, there are merits and demerits, and processing accuracy and cost are not necessarily satisfied. That is, although a method of directly processing a work with a superabrasive grindstone has a sufficient grinding ability, a rough finished surface leaves a problem in gear quality. In addition, the equipment cost was high because both the grindstone and workpiece shafts used a forced drive system.

It can be easily processed, but Japanese Patent Application No. 5-2001
The base metal of an internal gear type electrodeposition grindstone as a rough internal tooth grindstone as disclosed in No. 61 cannot be easily machined by hobbing or the like. In particular, in helical gear machining, in the case of external gear shape machining, by adjusting the torsion angle of the hob, it is possible to obtain external gear shapes having various torsion angles, while internal gears account for approximately 90%.
