Notes:
9Cr18 is a type of martensite stainless steel. It has high hardness, chemical stability, fineanticorrosion, wearable and quench stability. It has been used in different areas withhigh-anticorrosion and high polishing surface as mirror. So it requires for the high level surfacequality after lapping and polishing. In this paper, the surface quality (surface roughness and flatness)of 9Cr18 is discussed with lapping parameters which include velocity, load and time distribution oftwo lapping steps(rough lapping and Ultra-precision lapping). In order to optimize those parameters,an optimization experiment for lapping 9Cr18 with Al2O3 was designed by Taguchi method. Finally,the optimum condition of each factor can be determined that speed: 80rpm, load:3.0kPa, and timedistribution: rough lapping time=15min, Ultra-precision lapping time=45min are the optimumconditions for both Ra and Wt
