Saint-Gobain Abrasives has combined a new engineered abrasive grain and an innovative manufacturing process, VORTEX Technology, which carefully 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, which represents a complete breakthrough from classical porous wheel technologies, 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. The patented VORTEX Technology does not require the use of artificial pore inducers (chemicals), thereby helping to preserve the environment. VORTEX Technology enables users to achieve significant improvements to the manufacturing process such as ~50% higher maximum MRR (Metal Removal Rate) at a constant power, grind at ~20% lower power at a constant MRR, 90% reduction in scrape and 335 reduction in diamond dresser cost.
