Abstract: This study presents the strong retention of the grains on the resin matrix with active braze coating diamond (ABCD) wire to have longer tool life. There were three kinds of diamond grain of bare diamond, Ni coated diamond, and ABCD in resin-bonding diamond wire saw. In order to discuss the tool life of three kinds of diamond grain, we have developed a technique to determine cutting regime based on the cutting parameters and observation of the chip type. Finally, we found the ABCD grains had strong retention on the resin matrix, so the ABCD wire saw had great tool life.

Keywords: ductile materials; alumina slicing; active braze coating diamond; ABCD wire; brittle materials; diamond wire saw; tool life; diamond grains; resin matrix; cutting parameters; chip type.
