摘要

Achieving both high surface quality and a high material removal rate (MRR) in precision grinding of Zerodur remains a significant challenge. In this study, the formation mechanism of the glass-ceramic grinding surface under multi-parameter coupling is systematically explored through theoretical modeling and experimental verification. Based on the assumption of rigid conical abrasive particles, a theoretical model for surface roughness (Ra) and material removal rate (MRR) was established. The influences of grinding wheel particle size, normal pressure, feed rate, and feed speed on Ra and MRR were then revealed and verified through systematic experiments. The results show that grinding wheel particle size has the most significant effect on Ra. Specifically, using a 1000# wheel reduced Ra by approximately 60% compared to a 600# wheel. MRR increases significantly with grinding wheel particle size and normal pressure, whereas surface quality decreases. The feed rate and feed speed have little effect on Ra, but can effectively improve MRR; increasing the rotational grinding wheel speed can improve the surface roughness to a certain extent, but its effect on improving MRR is limited. This study confirms that by optimizing the combination of grinding wheel particle size, normal pressure and motion parameters, high-efficiency grinding of Zerodur can be achieved under the condition of ensuring surface quality.
