摘要
固结磨料精磨工艺具有加工效率高和清洁方便等突出优点。采用正交实验法,研究了精磨压力、时间、转速和抛光液浓度等参数对固结磨料精磨手机面板玻璃的材料去除率MRR和表面粗糙度Sa的影响,并综合优化获得高材料去除率和优表面品质的工艺参数。结果表明精磨的最佳工艺参数组合为:精磨压力为0.1 MPa,转速为160 r/min,精磨时间5 min,抛光液浓度10%。
Fixed abrasive fine grinding has many advantages such as high machining efficiency, easy cleaning and so on. An or- thogonal test is used to research on the effect of pressure, speed, time and the concentration of polishing slurry on the material re- moval rate MRR and average surface roughness Sa of glass panel for cell phone. The optimized process parameters for the high ma- terial removal rate and good surface quality are obtained. The results show that the optimal parameters are pressure 0.1 MPa, speed 160 rpm, grinding time .5 min and the concentration of polishing slurry 10%.
