ビトリファイドCBN砥石の新工具によるインボリュート内スプライン歯面の仕上げ法

抄録

In high accurate and high efficient tooth finishing, a vitrified CBN (cubic boron nitride) wheel or a electro-deposited CBN wheel shows superior performance. And honing by a involute spline tooth meshing is profitable due to the generating motion. However, a lack of wheel rigidity and an inadequate feeding motion of the wheel trend to reduce 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 a electro-deposited wheel. And the finishing by braking a internal spline axis is carried out. The influence of different feeding methods is investigated on the finished tooth surface roughness. The finishing by using a vitrified CBN wheel and braking a internal spline axis shows superior performance.
