Grinding Belts, High Performance

Bharat Udyog offers Hermesit range of pure high performance Grinding Belts from Hermes Abrasives Group, Germany. These long life grinding belts have special hollow spheres covered with grain and produce the typical Hermesit finish, the so-called “Hermesit bright effect”. When grinding with Hermesit abrasives, the roughness depth of the surface of the ground workplace is the same through out the lifetime of a belt. When grinding with conventional abrasives, an even surface quality can be achieved for only a relatively short time. The abrasive grain becomes blunt and the desired initial roughness depth drops considerably. As the hollow spheres coated in abrasive grain wear down, new grain is constantly being exposed. Product benefits: consistent surface finish and roughness values on workplace, throughout tool life; 3 to 5 times the tool life improves economy compared to conventional grinding belts; reduced grinding belt change times; reduced disposal costs for used grinding belts; and lower grinding temperatures. Recommended use: when using new Hermesit grinding belt, Hermes recommends the belts are dressed prior to full productions runs. This can be achieved by grinding two sheets, for example, in order to dress the hollow spheres and achieve the desired finish and optimum performance. When grinding different widths of sheet metal, the wider sheets should be ground first to prevent running-in racks. Product specifications: 1. Type Hermesit RB 535 X; grain – aluminium oxide (hollow sphere); bonding – Resin; backing – X-Cloth; and gritrange – P –150 – P 320, P 400, P 600; and 2. Type Hermesit RB 545 X; grain – silicon carbide (SIC) (hollow sphere); bonding – resin; backing – X-Cloth; and gritrange – P 150 – P320, P 400, P 600, P 800. Warning: sheet metal thicknesses – <0.6 mm cannot be machined with Hermesit grinding belts.
