Tools Used - West Midland Grinding

Dressing refers to the process of re-sharpening the very small cutting edges that cover the surface of the grinding wheel. We use diamond tools and wheel dressers to fracture the abrasive grains on the grinding wheel and produce sharper new edges in the process. This simultaneously cleans the spaces between the grains, eliminating metal dust and other particles that can act to clog the face of the grinding wheel.
