Abstract: The main questions of current multi-layer sintering superabrasive tools are that their grains easily fall off from the matrix, the cuts of them difficultly outcrop in machining process, and grains load and grinding is not in proportion because of the stochastic grain distribution. The improving strategies and proceedings about these are reviewed. A new generation mono-layer brazing superabrasive tools and its encouragements are described. The advanced project is put forward to fabricate the renewal product of multi-layer superabrasive tools with brazing instead of sintering, exploiting new technology of the three-dimensional optimum distribution of grains and holes through using the experience of porous metal fabrication technology.
