Abstract

PURPOSE:To improve the joint strength of an installation part of a chip to a blade and prevent a removement from the blade by projecting a chip installation seat to one side of the blade for formation, and engaging a recessed part provided in the chip with the chip installation seat to be blazed. CONSTITUTION:A chip installation seat 103 is projected to one side of a blade 101 with the predetermined pitch for formation, and on the other hand, a recessed part 107 is formed in a diamond chip 105. Next, in the case that the diamond chip 105 is fixed to the chip installation seat 103 of the blade 101, the recessed part 107 is engaged with the chip installation seat 103 to joint them by blazing. Namely, the blazing alloy is welded-in from the outside to be intruded to a joint face of the both and solidified, the diamond chip 105 is fixed strongly to the chip installation seat 103 of the blade 101. Consequently, a trouble that the diamond chip 105 is removed from the chip installation seat 103 of the blade 101 during the cutting can be prevented previously.
