Grinding Brittle Materials | 2013-08-06 | Ceramic Industry

When a brittle material needs to be brought to final dimension by hard grinding, it will not exhibit plastic deformation as the diamond grit plows through it to remove material; nor will it exhibit the residual stress profile of a ductile material. Instead, the material will crack, leaving micro-cracks that remain as sub-surface damage. The key to grinding brittle materials …

Hard, brittle materials generally require a wheel with a fine grit size and a softer grade. Hard materials resist the penetration of abrasive grains and cause them to dull quickly. Therefore, the combination of finer grit and softer grade lets abrasive grains break away as they become dull, exposing fresh, sharp cutting points. On the other ...
