Abstract
An experimental investigation is carried out to machine SiC ceramic material through method
of high speed plane lapping with fixed abrasive. The results show that the material removal mechanism
and the surface roughness are chiefly related to the granularity of abrasive and the lapping pressure for the
brittle materials such as SiC ceramic. It is easily realized to machine SiC ceramic material in ductile mode
with a high efficiency and a low cost using W3.5 grit under a lapping pressure of 0.1MPa and then a
smooth surface with surface roughness of Ra 2.4nm can be achieved.
