ABSTRACT:
An apparatus for truing and dressing a grinding wheel made of cubic boron nitride is provided. A support head supporting a truing wheel and another support head supporting a dressing roll are separately and independently arranged on a wheel support of a grinding machine. The truing wheel is rotated in the same direction as is the grinding wheel so as to true the grinding wheel in an up-cut manner, and the dressing roll is rotated in a direction opposite to that of the grinding wheel so as to dress the grinding wheel in a down-cut manner. The dressing roll is fed toward the grinding wheel to be ground thereby and then returned a predetermined amount away from the grinding wheel prior to a truing operation.
