Abstract
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 Si3N4(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.
