Title:
ABRASIVE PRODUCT
Document Type and Number:
WIPO Patent Application WO2002009909
Kind Code:
A3
Abstract:
An abrasive product which comprises a polycrystalline mass of self-bonded abrasive particles of irregular shape, the product being substantially free of a second phase and containing substantial plastic deformation of the abrasive particles. The abrasive particles are preferably diamond or cubic boron nitride and the plastic deformation of the particles is preferably at least 0,3 percent. The abrasive product may be made by subjecting a mass of the particles to elevated temperature and pressure conditions.
