Abstract
The invention discloses a metal-bonded diamond grinding wheel prepared by self-propagating pressure-less sintering and a preparation method thereof. The metal bonded diamond grinding wheel mainly comprises a working layer and a non-working layer, wherein the working layer comprises metal bond and grinded diamond, the non-working layer is metal bond, and the metal bond in the working layer and non-working layer have the same components that comprise metal powders of Cu, Al, Ni, Ti, Sn, and Co. To prepare the metal-bonded diamond grinding wheel prepared by self-propagating pressure-less sintering solves the problems of high energy consumption and low manufacture efficiency in the current sintering processes of the metal bonded diamond grinding wheel, and improves the binding force of the metal bond to the grinded diamond by forming carbides between the bond and the grinded diamond.
