Abstract
The invention provides a method of manufacturing an abrasive body which includes the steps of providing a mixture comprising a mass of nanosized ceramic particles and a mass of ultra-hard abrasive particles, typically diamond and cubic boron nitride, and sintering the mixture into a coherent body. The sintering conditions used are hot-pressing conditions.
Claims6
A method of manufacturing an abrasive body comprising the steps of:
- providing a mixture comprising a mass of nanosized ceramic particles and a mass of ultra-hard abrasive particles comprised of diamond or cubic boron nitride particles, wherein the ultra-hard abrasive particles in the mixture do not exceed 35 percent by volume of the mixture;
- and
- sintering of the mixture into a coherent body at a temperature of 800.degree. C. to 1500.degree. C. and a pressure of up to 300 MPa.
