    In grinding with a comparatively heavy feed, and a mininum number of passes, the speed may not exceed 2 ½ or 3 fpm(076–09 m/min) If very light feeds are employed, as in grinding hardened highspeed steel, the work speed may be much higher than 3 fpm(09 m/min) and should be determined by test If excessive heat is generated by removing stock too rapidly, a work speed reduction is one· The angle of the workpiece rest blade is also critical For example, when grinding with a 4” (1016 mm) wide superabrasive wheel, the rest blade will generally work well at 30º But with a wheel width of 6” (1524 mm) or 8” (2032 mm), that same angle may generate too much pressure toward the grinding wheel and cause chatter In this case, changing the angle to 20º or 25º will reduce the pressure8 Principles of Centerless Grinding Metal CuttingSpecialists in highpressure grinding Köppern’s long history is linked to the utilization of roller presses in briquetting and other compaction processes A major technological breakthrough came with the introduction of highpressure comminution in the mid1980s This innovative application for the cement and minerals processing industries required a completely new approach to the question of wear protection for these high pressure grindingMaschinenfabrik Köppern Der Spezialist für
