ABSTRACT:
An apparatus for successively truing and dressing a grinding wheel made of cubic boron nitride (CBN) with a diamond-impregnated truing roll and a metal dressing roll. The truing and dressing rolls are rotatably mounted on a roll carriage which is slidably mounted on a grinding machine so as to feed the rolls toward the CBN wheel and thereafter traversely move the rolls along the wheel surface of the CBN wheel. After truing with the truing roll, a coolant fluid mixed with liberation abrasive grain is supplied toward a gap of a predetermined distance, smaller than the mean size of the abrasive grain, which is established between the CBN wheel and the dressing roll, so that the liberation abrasive grain acts to grind and remove bond material from the wheel surface in order to accomplish the dressing of the CBN wheel.
