A new traverse grinding technique with the grain size variation wheel, in which grain size is varied layer by layer along wheel width, is introduced for improving both efficiency and surface finish. The grain size variation wheel has the leading part of coarser grain and following finer grain parts on the acting wheel surface, and the leading part of coarser grain removes mainly metal and following parts of finer grain sizes improve surface finish. The traverse grinding process is experimentally analyzed and compared with the conventional one to prove that the new technique is available for higher efficiency and better surface finish as compared with the traditional one, because the whole width of the grain size variation wheel is effective and respective parts on the acting wheel surface play respective roles. The grinding ability of the grain size variation wheel is also maintained well for long grinding time and therefore the surface finish and the grinding force are kept constant with grinding time in the traverse grinding, because the wear rate of the grain size variation wheel is lower than that of the traditional wheel.
