Grinding Wheel Prevents Aluminum Clogging, Loading

Jan. 8, 2019
Cotton fibers break down naturally as heat is generated, resulting in constant sharp grit being exposed to the workpiece

REX-CUT ABRASIVES introduced the Aluminator T27 grinding wheel, calling it "a new solution" that prevents clogging and loading. Typically when grinding aluminum, bonded wheels overheat the metal, causing chips of aluminum to embed in the grinding wheel — a result commonly referred to as clogging or loading. Eventually there will be no grit exposed, only deposits of aluminum on the face of the wheel. Normally a wax or other grinding aid would be necessary to prevent it.

Cotton fibers that form the Aluminator T27 the break down naturally as heat is generated, resulting in constant sharp grit being exposed to the aluminum workpiece. This eliminates loading, downtime, and the need and expense for wax or grinding aids.

The Aluminator offers increased grinding action, improved surface finishing, smooth operator control, and long life.

“One complaint we hear from fabricators working with aluminum is the need to take extra time to thoroughly clean lubricant residue from work surfaces after grinding. This happens either because of grinding aids added to structure of the abrasive product, or waxes used in conjunction with grinding wheels,” according to R&D manager Jon Blake. “When we designed this wheel, we kept in mind the need for an aluminum grinding wheel that will grind fast and consistently while being 100% lubricant-free. This allows fabricators to grind and move on to the next step without stopping to clean their work piece.”

The Aluminator is available in 4.5-, 5-, and 7-in. diameters, in 36 grit.
