July 10, 2019 - Lawson Products Inc., Chicago, announced the new Blue-Kote™ Soft Material Application Flap Disc, which grinds aluminum and all non-ferrous metals at high speed with minimal clogging or loading, while keeping the work surface temperature low for quality finishing.

The Type 27 abrasive disc is also used with composite materials such as carbon fiber and plastics. The 4.5-inch diameter disc is available in 40 and 60 grit.

Produced exclusively for Lawson Products, the new Blue-Kote Soft Material Application Flap Disc is manufactured from tough aluminum oxide grain layered in a specially engineered net structure. The unique design provides high-performance cut rate and aggressive stock removal with surface blending action for excellent finish consistency. The soft, long-lasting disc that simultaneously grinds and finishes saves process time, eliminates the need for product changeover, and reduces total cost.    

Because aluminum has a much lower melting temperature than other metals, keeping aluminum cool while grinding and finishing is a big challenge for welders and fabricators. The Blue-Kote disc cloth’s net structure resists clogging on soft materials, and its sanded surface stays cooler and avoids burning the work surface.

December 18, 2018 - Rex-Cut Abrasives, Fall River, Massachusetts, announces the Aluminator, a new solution to Aluminum Grinding that prevents clogging and loading.

Typically when grinding aluminum, bonded wheels overheat the metal causing chips of aluminum to embed right into the grinding wheel, this is 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 grinding aid would be necessary to prevent this issue, but that is no longer the case.

Rex-Cut’s new Aluminator T27 Cotton Fiber Grinding Wheel grinds aluminum without any clogging or loading. Cotton Fiber Wheels naturally break down as heat is generated, resulting in constant sharp grit being exposed to the aluminum work piece. This eliminates loading, costly downtime, and the need and expense for wax or grinding aids. The Aluminator offers increased grinding action, greatly improved surface finishing, smooth operator control, and long life. With less noise, less vibration, and safer operating conditions; the Aluminator T27 Cotton Fiber Grinding Wheel is assured to make your Aluminum grinding experience smooth.

“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 from either grinding aids added to structure of the abrasive product, or waxes used in conjunction with grinding wheels,” states Jon Blake, R&D Manager. “When we designed this wheel, we kept in mind the need for an aluminum grinding wheel that will grind fast and consistent 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 now available in 4.5 in., 5 in., and 7 in. diameters, in 36 grit.
