Abstract:
1. A metal-bonded diamond grinding wheel prepared by self-propagating pressure-less sintering, which mainly comprises a working layer and a non-working layer, the working layer comprising metal bond and diamond grain, the non-working layer being metal bond, wherein the components of the metal bond of the working layer are the same as those of the non-working layer, characterized in that, the components of the metal bond comprise metal powders of Cu, Al, Ti, Ni, and Sn, and optionally Co powder, wherein said metal bond satisfies the requirements of self-propagating pressure-less sintering, and said metallic powders have a part of weight ratio of Cu:Al:Ti:Ni:Sn:Co=50˜80:3˜20:5˜20:5˜20:4˜10:0˜5.
