摘要

To improve the material removal rate and surface quality in quartz glass lapping processes, a novel ternary-phase resin fixed abrasive pad (FAP) was developed. Using polyurethane acrylate, epoxy resin, and hydroxyl-terminated polybutadiene (HTPB) as resin matrices and W7SiC as fixed abrasives, the FAP was prepared by a thermosetting process. The effects of resin ratios on the machining performance of FAPs were investigated through quartz glass lapping tests and friction–wear experiments, with the material removal rate (MRR), surface roughness (Ra), friction coefficient (FC), and hardness (HD) used as evaluation indices. The results show that the optimized FAP yields an optimal surface roughness Ra of 15.376 nm when lapping quartz glass, along with a maximum material removal rate of 129.6389 nm/min. This study systematically investigates the influence of thermosetting resin proportions on the mechanical, wear-resistant and surface properties of fixed abrasive pads, and provides a new strategy for the high-efficiency lapping of quartz glass.
