  • (A) a shaft for rotation;

    (B) at least two abrasive-bladed cutting wheels each consisting of a base wheel having a center opening for insertion of the shaft and an abrasive blade layer bonded to the outer periphery of the base wheel, each cutting wheel being fixed on the shaft inserted into the center opening therein; and

    (C) at least one spacer, the number of the spacers being smaller by one than the number of the abrasive-bladed cutting wheels, having a center opening for insertion of the shaft and fixed on the shaft by inserting the shaft into the center opening at a position between two abrasive-bladed cutting wheels to define the spacing therebetween, the base wheel of the abrasive-bladed cutting wheel being made from a cemented metal carbide having a Young'"'"'s modulus in the range from 45000 to 70000 kgf/mm2 and the abrasive blade layer of the abrasive-bladed cutting wheel being made from particles of an abrasive material bonded together with a bonding agent.
