摘要
随着全球技术革新的不断发展,精密零件的工艺性能日益提升,同时对于超精加工的要求也越来越高,尤其是复杂的曲面类零件很难加工。本文针对曲面类零件具有多曲率的特性,研制出能够抛光曲面的新型抛光装置,可以实现曲面类零件高效和高质量的抛光。通过试验研究发现,不同抛光速度和磨料浓度对表面粗糙度、材料去除率及表面质量影响很大,使用新型的装置抛光曲面类零件,工件表面粗糙度可以达到Ra 10nm左右,达到了镜面的效果。
With the global technological revolution,the process performance of precision parts has been getting better, the requirements for ultra-precision machining are increasing at the same time,especially for the complex surface that is dif-ficult to process.According to multi-curvature property of complex surface,a new polishing apparatus was developed,and high efficient and high quality polishing results can be achieved with this polishing apparatus.In the polishing process, roughness,removal rate and surface quality are the evaluation indexes of polishing results by changing the polishing speed and concentration of the slurry.The results showed that by using the polishing apparatus,the roughness can reach around 10 nm,and there were no any scratches on the polished surface.
