Abstract
For highly accurate and highly efficient tooth surface finishing, a vitrified cubic boron nitride (CBN) wheel or an electro-deposited CBN wheel exhibits superior performance. Honing by an involute spline tooth meshing is effective due to the generating motion. However, a lack of wheel rigidity and an inadequate feed motion of the wheel tend to reduce the finishing performance. As a result, it is difficult to keep the tooth surface smooth. In this study, the finishing with a vitrified CBN wheel is carried out using a new honing tool. The finishing performance is compared with that obtained using an electro-deposited wheel, and the finishing is carried out by braking an internal spline axis. The influence of different feed methods is investigated on the roughness of the finished tooth surface. The finishing using a vitrified CBN wheel and braking an internal spline axis shows superior performance.
