Grinding performances of directionally aligned SiC whisker wheel

摘要

This paper examines the grinding performances of directionally aligned SiC whisker wheel. The effects of various parameters of wheel on the surface finish are clarified. The considered parameters related to the grinding wheel design were thesegment width, whisker diameter, additive and bonding material. The experimental results are as follows: (1) The smaller the diameter of whisker and the narrower the segment width, the better the surface finish. Moreover, the resin bonded wheel withchromium oxide additive has produced the best surface finish; (2) The ultra fine grinding chips and the finished surface have been observed and the finished surface was analyzed by laser interferometer and atomic force microscopes; (3) Surface finish with a roughness value of 1.5nmRa has been successfully obtained.
