To solve loading of grinding wheels, a porous metal-bonded diamond wheel allowing ground chips to invade the porous base material was fabricated. Fe-Cu and Fe-Cu-C type samples were prepared by the plasma discharge sintering method feasible in a short time, and the open porosity and Brinell hardness of the samples were measured. The sample formed by sintering Fe-2Cu-2C at 1273K showed a Brinell hardness of 220, exceeding the hardness of current materials. A graphite type sample having a wheel-like shape and a devised current-carrying passage was fabricated and sintered to obtain a wheel provided with a spindle.
