Brown corundum resin abrasives are in sharp shapewith low bulk density and strong self sharpening. the bonded abasives made from brown corundum resin abrasives are sharp, with good heat dissipation and high grinding efficiency.
the production of ordinary resin abrasives, the processing of;ow carbon steel and alloy steel.
