3M™ Trizact™ Cloth Belt 337DC

The 3M™ Trizact™ Cloth Belt 337DC delivers consistent intermediate to final finishes on medium pressure applications. Designed with aluminum oxide and a grinding aid on a durable X- weight cloth backing, this belt is available in widths from 1/2 to 24 inches (1.27 cm to 70 cm) and grades from A300 to A30.The 3M Trizact Cloth Belt 337DC owes its durability and sustained cut rate to its uniquely engineered bricks and channels microreplicated abrasive structure. Uniform abrasive "bricks" keep fresh cutting mineral constantly at the working surface and channels sweep debris away to discourage loading and keep the substrate clean. The bricks consist of layers of mineral and grinding aid, up to 4 times as much as conventional aluminum oxide belts of the same grade. These dense layers of abrasive mineral lead to extra-long life and extremely consistent performance. The grinding aid protects heat-sensitive alloys from damage and reduces rework. Building upon the principles of microreplication, 3M scientists developed larger, more diverse abrasive structures cubes, spheres, ridges identical in shape and optimized for a variety of applications. Microreplication allows 3M to design abrasives with varying shapes and formulations, to control the level of breakdown, cut, finish, and life. These abrasive structures are arrayed precisely and uniformly across a film or cloth backing in a pattern calculated to deliver sustained cut rate and eliminate belt-to-belt variation. 3M Trizact Abrasives were developed especially for finishing more difficult processing materials like titanium, cobalt, stainless steel, as well as all exotic alloys in the aerospace, aviation, and medical industries. Also effective for finishing applications on carbon steel, copper, bronze, aluminum, composite materials, and synthetics.
