Abstract: To address the issues of low efficiency and high cost caused by the short lifespan and timeconsuming repeated dressing of alumina grinding wheels in form grinding processes, and to promote the application of dressing-free cubic boron nitride (CBN) form grinding wheels in batch gear grinding, this study proposes a design method and verification scheme for the profile of disc-shaped dressing-free CBN form grinding wheels. The research focuses on the precise profile design of grinding wheels suitable for the form grinding of external helical gears. The results show that accurate calculation of the grinding wheel tooth profile can effectively ensure the precision of the wheel morphology, eliminate the dressing step, and thereby improve grinding efficiency while reducing production costs. This study holds significant engineering implications for promoting the widespread application of form grinding technology in batch gear processing.
