CA 2576891

Organic bonded abrasive tools, having controlled microstructures, comprise a relatively low volume percentage of abrasive grain and a relatively low hardness grade, but are characterized by the excellent mechanical strength and efficient grinding performance of much harder grade, lower porosity tools, especially in versatile grinding processes, such as centerless grinding. A method for centerless grinding with these tools is provided. Methods for making the abrasive tools utilizing agglomerated abrasive grain are described.

L'invention porte sur des outils abrasifs liés par voie organique, pourvus de microstructures contrôlées, qui ont pourcentage en volume de grain abrasif relativement bas et un grade de dureté relativement bas, mais qui se caractérisent par une remarquable résistance mécanique et par une performance de rectification efficace à un grade beaucoup plus dur, sur des outils présentant une faible porosité, en particulier dans des procédés de rectification polyvalents, tels que le procédé de rectification sans centres. L'invetion concerne un procédé de rectifications sans centres avec ces outils. L'invention porte également sur des procédés de fabrication d'outils abrasifs à partir de grains abrasifs agglomérés.
