Patent ID: 7491251

Claim:
A method of making an abrasive product, the method comprising: a) providing a substantially horizontally deployed backing; b) providing a dry flowable particle mixture comprising abrasive particles and particulate curable binder precursor, wherein the abrasive particles have an average particle size of 45 microns or less; c) depositing a layer of the dry flowable particle mixture onto the backing; d) sintering at least a portion of the layer of the dry flowable particle mixture to provide a cohesive layer wherein adjacent abrasive particles are adhered to one another by the curable binder precursor; e) compacting the cohesive layer to provide a compacted layer; f) at least one of embossing or at least partially cutting the compacted layer to provide curable shaped structures having a distal end spaced from the backing and an attachment end adhered to the backing; and g) at least partially curing the curable binder precursor to form shaped abrasive structures comprising abrasive particles and a binder, the shaped abrasive structures being affixed to the backing.
