This study examines the measuring grinding force and temperature in the workpiece of cast iron (FC200) in ultra-high speed grinding out-off. As the grinding condition under the rate of the table speed v and the wheel peripheral speed V (i. e. v/V) was constant, V was increased. When v/V and V were large, bum mark was occurred. As V was increased, the normal grinding force component was decreased, but the tangential grinding force component was increased when V was over 100m/s. These phenomena indicate that the friction force on the side of grindstone increase when V is large. On the other hand the temperature in the workpiece near the side of grindstone was higher than that near the wheel working surface when V was large. From these result, it seems that the friction heat on the side of grindstone increase at ultra-high speed grinding cut-off. Therefore, it will be necessary to develop the coolant device.
