Dressing sticks for resin- and vitrified-bond superabrasive (diamond and cubic boron nitride) grinding wheels are made of grade 38A aluminum oxide, which is friable and has high-purity for use on super-abrasive wheels.
Rubber-bond finishing sticks are made of grade 57A aluminum oxide and are used for dressing, truing, and die polishing when high-precision tolerances are required. The rubber bond helps maintain a cool surface. Grade 57A is a semifriable, fused brown aluminum oxide for cool, burn-free grinding of heat-sensitive metals and all steels. It balances cut quality and wheel life span at light to medium feed rates.
