为提高研磨液加工效率，改进工件表面加工质量，采用表面改性技术、助剂复配技术、超声分散技术，制备了一种蓝宝石加工用高效水基金刚石研磨液。使用该研磨液对蓝宝石进行研磨加工，可实现材料去除速率1.35μm/min、表面粗糙度值 Ra16 nm、表面无明显划痕等优异研磨加工效果。将自制的研磨液与同类研磨液产品的使用性能进行对比分析，结果表明：自制的金刚石研磨液在材料去除速率、加工后工件表面粗糙度值 Ra以及表面划痕方面均优于其他同类产品。%To improve the efficiency of lapping and the quality of workpiece surface, surface modification technology,fertilizer compound technology and ultrasonic dispersing technology were used to make high-performance water-based diamond slurry.Application of the diamond slurry on lapping sapphire showed excellent lapping performance,such as material removal rate of 1.35 μm∕min,R a value of 1 6 nm,and no obvious surface scratches.Comparing self-made slurry with domestic and foreign slurries,it was showed that self-made diamond slurry had better removal rate,lower sapphire surface roughness value and less scratches.
