16/8/10 – New Abrasive Grinding Belt from 3M
3M have unveiled its new aluminium oxide abrasive belt. The company says that the new product has a longer life, high productivity and consistency in operation.
The 3M Cubitron II 984F Abrasive Belt is the first of a new line of premium belts manufactured with what the company says is an innovative abrasive grain technology.
The 3M Cubitron II Abrasive Products incorporate precisely-shaped, uniformly-sized and vertically-oriented triangles of ceramic aluminium oxide. (Fig. 1). These aluminium oxide triangles break off as they wear to reveal a new layer of sharp points and edges that slice cleanly through the metal surface, effectively offering a self-sharpening action.
The first product in the new range, the Cubitron II 984F Abrasive Belt delivers up to 30% faster cutting times even on tougher metals such as stainless steel, carbon, nickel alloy and cobalt chrome.
3M says that its is suited for foundry and investment casting applications such as gate or joint line removal.
The unique mineral configuration diverts heat away from the workpiece and belt and into the swarf, reducing the risk of discolouration and the likelihood of heat-related stress cracks. The faster, sharper cut can lead to faster cycle times on automated equipment and also lessens the amount of pressure the operator needs to apply on manual belt machines, so lowering operator fatigue.
Plus, as the abrasive stays cooler and sharper, product life is extended significantly. In 3M’s own surveys, the new product has been demonstrated to take twice as long as competing products to reach the typical point at which operators stop using a belt – when performance drops to two-thirds of its initial cut rate.
The new belt is currently available in grade 36+ which combines the strength of a 24 grit product with the finish quality of a 40 grit product.
Jim Arbuckle of 3M’s Abrasive Systems Division commented: “The enhanced cutting power of the new 3M Cubitron II 984F Abrasive Belt is a result of extensive research and development by 3M’s dedicated team in the US and represents a breakthrough in performance and durability.
“The product has already been successfully launched in the US where foundry customers producing castings for the aero engine, medical implant, automotive and gas turbine markets have reported significant cost-down benefits and productivity gains. “
