Deterministic Microgrinding, Lapping, And Polishing Of Glass-Ceramics

A series of microgrinding and polishing experiments on glass-ceramics is reported in this paper. Microgrinding includes deterministic microgrinding (two-body abrasion at fixed infeed rate) and loose abrasive lapping (three-body abrasion at fixed pressure). We correlate material mechanical properties (Young's modulus, hardness, fracture toughness) and chemical properties with the quality of the resulting surface. Determining microgrinding (at fixed infeed) and loose abrasive microgrinding in terms of material removal rates and resulting surface quality were compared.
