Abstract

Very hard cerment is made by mixing 25 vol % diamond grains of 0.8 mm dia with 75 vol % of an alloy powder mixing thoroughly to obtain a regular distribution of diamonds throughout the mass and hot pressing to produce a matrix of alloy with hardness RA > 85. The loss of diamond during mfr. is 1 wt. %. Grinding wheels are produced and having good wear resistance without blunting due to worn cutting edges on the diamonds as experienced with larger diamond grains.
