Using a commercially available alloy such as BNi2 which contains the active elements Ti and Cr, and a self-made CuSnNiTi alloy as an active filler materials, a monolayer brazing diamond grinding wheel has been made in a vacuum furnace. Using thermal analysis (DSC) and EDX, it was shown that at appropriate an brazing temperature, duration and vacuum level, chemical bonding takes place among the diamond, brazing alloy and substrate, and that different bonding strengths and performance accompany the use of various brazing filler alloys. Since CuSnNiTi alloy wets the diamond surface, the brazing temperature can be reduced and the bond strength can be enhanced greatly. Grinding tests show that the matrix with this particular filler strongly retains the diamond, and that the cutting efficiency is increased at constant cutting life.
