Method of making a cutting tool |
摘要 |
A method for producing a cutting tool such a twist grill, end mill, or the like. The method provides an unbonded assembly including a cylindrical core having ends and an elongate side surface covered partially or completely by a coherent, unsintered layer including ultra-hard abrasive particles for producing an ultra-hard material. The unbonded assembly is subjected to elevated temperature and pressure conditions at which the ultra-hard abrasive is crystographically stable. The sintered product is then recovered that includes a cylindrical core and a layer of ultra-hard abrasive material bonded to the core, and the sintered product is worked to produce one or more cutting edges in the layer of ultra-hard abrasive material. |
