3M™ Trizact™ cloth belt 307EA uses proprietary micro replication technology where micron graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on a rayon backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish. The abrasive and resin structure for the 3M™ Trizact™ cloth belt 307EA is formulated to breakdown under medium pressure and keep fresh, sharp mineral cutting to provide consistent finishes on hard metals such as carbon and stainless steel. The belt also features a grinding aid that helps prevent heat buildup, warping and discoloration. The belt is constructed on a durable cloth backing that helps provide control, conformability and effective medium pressure grinding. The resin bonded abrasive gives you greater heat-resistance and helps prevent delamination. The belt uses a film media splice, a strong secure bond joining the belt ends, consisting of a thin film joining media that minimizes \"chatter marks\", ensures a smooth running belt and consistent finishing results. When compared to conventional abrasive products, proprietary Trizact™ abrasives produce a finer finish, achieve results faster and last longer. Robotic metal polishing demands the most consistent, refined cut and long abrasive life. 3M™ Trizact™ abrasives can consistently deliver near mirror finishes while also delivering the abrasive life that helps reduce change outs and downtime in robotic cells. This helps maximize the efficiency of the cell, allowing you to produce more parts per belt. Unlike conventional abrasives, 3M™ Trizact™ belts start sharp and stay sharp, resulting in more predictable finishes and improved, consistent quality. 3M™ Trizact™ belts can last up to five times longer than conventional belts and provide precise finish control such that operators can reduce grade sequences, requiring fewer process steps and fewer abrasive products. 3-dimensional structures uniformly distributed over the entire surface of 3M™ Trizact™ abrasives ensure consistent performance and eliminate part to part variation.
