Saint-Gobain Abrasives has combined a new engineered abrasive grain and an innovative manufacturing process -- VORTEX(TM) technology, which controls grinding wheel structure -- to create a highly porous and permeable grinding tool with unsurpassed abrasive grain spacing. This combination delivers a full array of production advantages, including high metal removal rates, improved form holding, long wheel life and a greatly reduced risk of metallurgical damage. VORTEX technology achieves optimum grain spacing without artificial pore inducers and delivers wheels that excel in grinding applications when applied to vitrified products with large contact areas. These wheels are designed for heat sensitive porous grinding, including creepfeed grinding, gear and surface grinding -- especially on difficult-to-grind materials such as nickel-based alloys.
