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.
