This paper deals with the surface topography and grinding mark on the surface, which is ground by high-speed reciprocation grinder. The vibration of the wheel spindle forms the grinding mark. Therefore, the imbalance of grinding wheel, which causes the vibration, should be eliminated. However, it is impossible to eliminate the imbalance from grinding wheel completely. The influences that the wheel spindle vibration gives for ground surface must be made clear. And the influence of wheel spindle vibration must be controllable. In this paper, the ground surface is measured by form measuring instrument to investigate a surface topograph. It is found that there is periodic micro topography on the ground surface, and shape of the micro topography changes by a difference of grinding marks. It indicates that the ground surface topography can be controlled if the grinding mark can be controlled. Therefore, the relationship between grinding mark and grinding parameters is investigated theoretically. As a result, it becomes clear that the grinding mark varies sensitively following the variation of the wheel vibration frequency of table reciprocation frequency, and the grinding mark generated by conventional grinding is easier to vary than by high-speed reciprocation grinding.
