Abstract
In this paper, a relation between the ground surface roughness and grinding phenomena of various fine ceramics is investigated by a systematical experiment. Results obtained are as follows : The state of ground surface corresponds to the surface generation phenomena per cutting edge.There is a near connection between the grinding force and the surface generation phenomenon, namely in grinding of fine ceramics, the brittle work materials produce low grinding forces and the grinding forces of ductile materials are relatively high. A grinding wheel, which is made of fine abrasive grains, make the work surface good in roughness;however, in this case, the effect of spark-out grinding on improvement of surface roughness decreases comparing with using rough grain wheel.
