In the ultra-smoothness vertical grinding method developed previously, the wheel surface conditions are found to influence on ground workpiece surface. Thus the building of wheel surface forming technique is important. In the report, from the point of view, the change of ground workpiece surface and wheel surface conditions with grinding process of silicon carbide ceramic is examined and discussed. In the wheel surface just after initial dressing having no worn cutting, the surface roughness is consisted of brittle fracture traces. The ductile mode grinding becomes possible when the worn cutting edges are formed largely on the wheel surface by grinding of silicon carbide ceramic. The ultra-smoothness vertical grinding is possible when the worn width of cutting edge becomes larger than the normal workpiece feed to grinding direction per a wheel revolution. Recovering dressing after the wheel life is necessary to be done under keeping the worn cutting edge on the wheel surface.
