SUPERHARD BODY,TOOL AND METHOD FOR MAKING SAME

摘要

A method for making a superhard tip for a rotary machine tool, the method including contacting at least one sintered polycrystalline superhard structure (22, 24) to a carrier body (30) comprising cemented carbide to form a pre- compact assembly (40), and subjecting the pre-compact assembly (40) to a pressure and temperature at which the superhard material is thermodynamicaliy stable to form a pre-form body for a superhard tip; and processing the pre-form body to form a superhard tip.
