T-Dress, A Novel Approach in Dressing and Structuring of Grinding Wheels

摘要

Since the grinding wheel topography directly influences the grinding forces and material removal mechanism, the dressing of grinding wheels has a decisive role in the desired product quality achievement. A new dressing concept is introduced in this paper in order to reach the optimum chip formation condition. The novel dresser, T-Dress, creates a new structure on the grinding wheel owing to which remarkable reduction in grinding forces occur. These lead to the lower heat generation in the wheel-workpiece contact zone and consequently lower thermal damages. The experiments prove about 40% lower grinding forces in grinding of bearing steel materials, 100Cr6, when dressing with T-Dress compared to the case of dressing with conventional profile rollers with almost no difference in the ground surface roughness values.
