Abrasive belt with angled shaped abrasive particles

Abstract

An abrasive belt having a backing and an abrasive layer adhered to the backing by a make coat resin and the abrasive layer comprising a plurality of shaped abrasive particles. A first belt side and a second belt side opposing the first belt side with the first and second belt sides generally aligned with a longitudinal axis of the grinding belt. The belt having at least 30% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 degrees and less than or equal to 20 degrees.

1 . An abrasive belt comprising:
 a backing and an abrasive layer adhered to the backing by a make coat resin and the abrasive layer comprising a plurality of shaped abrasive particles;   a first belt side and a second belt side opposing the first belt side with the first and second belt sides generally aligned with a longitudinal axis of the grinding belt;   at least 30% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 degrees and less than or equal to 20 degrees.   
     
     
         2 . The abrasive belt of  claim 1  wherein the shaped abrasive particles comprise a second face opposing the first face and a sidewall connecting the first face to the second face. 
     
     
         3 . The abrasive belt of  claim 2  wherein a perimeter of the both first face and the second face is triangular. 
     
     
         4 . The abrasive belt of  claim 3  wherein the perimeter is an equilateral triangle. 
     
     
         5 . The abrasive belt of  claim 1  wherein greater than 50% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 and less than or equal to 20 degrees. 
     
     
         6 . The abrasive belt of  claim 1  wherein greater than 75% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 and less than or equal to 20 degrees. 
     
     
         7 . The abrasive belt of  claim 1  wherein the angle is greater than 0 and less than or equal to 10 degrees. 
     
     
         8 . The abrasive belt of  claim 1  wherein the angle is greater than 0 and less than or equal to 5 degrees.
