Thermal expansion and wear of the grinding wheel are measured during cylindrical grinding by a new experimental method named "Radial difference comparison method". In this method, two grinding wheels are set together in flanges ; one is used for grinding and called as the working wheel, the other is racing and used for comparison of radial difference with the working wheel and is called as the reference wheel. The radial difference of two wheels is measured by means of blade method, and the thermal expansion and wear are obtained. As the result of experiment it is clear that the thermal expansion of the grinding wheel is far larger than the value of the wheel depth of cut. And when the temperature and thermal expansion are larger in the early stage of grinding, the wear is also large and the temperature and thermal expansion turn smaller in the late stage because of the decrement of the wheel depth of cut.
