- 論文の詳細を見る
A new griding method of ultra-high efficiency and high precision for ceramic balls is introduced.The principle of the grinding method is described and the grinding characteristics for Si_3N_4(Hot Isostatically Pressed, HIP)balls was investigated at grinding loads ranging from 2-40 N and drive shaft speeds ranging from 200-5000 rpm using diamond wheels of various grit sizes from 2μm to 100μm.Experimental results show that the method has a material removal rate as high as 29μm / min.The sphericity was improved and reduced from 43μm to 6μm within a very short grinding time of 6 minutes when a SD200 wheel was used.A sphericity of 0.12μm was obtained by using a SD8000 diamond wheel.
