method for preventing cracks in cutting and grinding.

摘要

To avoid cracks, cutting-off and grinding wheels (1) which have slots (3) running radially along the periphery are subjected to a secondary treatment by the area of the centre-side end of the slots (3) being exposed to a shot-blasting process. The shot-blasting process leads to stress relief of the material, to surface compaction and to radiusing of the edges in the area of the centre-side end of the slots (3). IMAGE
