Claims19
A method for abrading a metal surface of an object comprising:
- abrading the metal surface of the object using a centerless grinding apparatus, the centerless grinding apparatus comprising a coated abrasive having an engineered surface comprising a plurality of shaped abrasive structures adhered to a backing material wherein the structures comprise a cured formulation comprising a binder resin based on polymerizable acrylate monomers with abrasive particles uniformly dispersed in the binder resin wherein the proportion of binder resin in the formulation is 58 to 75% by volume.
A method for centerless grinding of a metal surface of a workpiece comprising:
- (a) supporting the workpiece between a regulating wheel and a portion of an abrasive belt backed by a contact wheel;
- and
- (b) contacting the workpiece with the abrasive belt, thereby grinding the metal surface of the workpiece;
- wherein the abrasive belt comprises a coated abrasive having an engineered surface comprising a plurality of shaped abrasive structures adhered to a backing material wherein the structures comprise a cured formulation comprising a binder resin based on polymerizable acrylate monomers with abrasive particles uniformly dispersed in the binder wherein the proportion of binder resin in the formulation is 58 to 75% by volume.

A centerless grinding belt comprising:
- (a) a backing material having a first portion and a second portion wherein the first portion is joined to the second portion to form a centerless grinding belt;
- and
- (b) an engineered surface comprising a plurality of shaped abrasive structures adhered to the backing material wherein the structures comprise a cured formulation comprising a binder resin based on polymerizable acrylate monomers with abrasive particles uniformly dispersed in the binder resin wherein the proportion of binder resin in the formulation is 58 to 75% by volume.
