When you read this, 40 years will have already passed since the discovery of spark erosion for machining polycrystalline cutting materials. Lach Diamant named this process "spark grinding," which accompanied the development of proprietary machines. Polycrystalline diamond tools conquered a multiple-application market traditionally reserved for carbides. Diamonds, baked under pressure and heat during synthesis, made this possible.
