Abstract
The invention provides a method of making an abrasive compact using conventional compact synthesis conditions. The method is characterized by the use of an ultra-hard abrasive particle mass comprising at least 25 percent by mass of ultra-hard abrasive particles having an average particle size in the range 10 to 100 microns, and consisting of particles having at least three different average particle sizes, and at least 4 percent by mass of ultra-hard abrasive particles having an average particle size of less than 10 microns. The abrasive compact is preferably a diamond compact.
Claims11
A method of making an abrasive compact which includes the step of subjecting a mass of ultra-hard abrasive particles to conditions of elevated temperature and pressure suitable for producing an abrasive compact wherein at least 25 percent of the mass of ultra-hard abrasive particles consists of particles having at least three different average particle sizes within an average particle size range of 10 to 100 microns and at least 4 percent of the mass of ultra-hard abrasive particles have an average particle size of less than 10 microns.
