drawback is they are tough materials to machine." Many of the new materials are so tough, grinding is the only economic and technical option," said Gaffney. "The Norton Virtium3 platform has a diverse selection to meet these new grind- ing needs. There are designs to run at high grinding wheel speeds. There are porous offerings that hold form, as well as traditional structure wheels that will grind the tough new mate- rials without producing damaging heat. The results are shorter grind cycles, longer wheel life, and better quality for customer applications," said Gaffney.


The key to any grinding process is to take into account all the elements of the grinding system—work material, abrasive product and the grinding machine including the fixturing, coolant system, wheel horsepower, overall stiff- ness and operating parameters. Norton Abrasives has a team of engineers that visit customer plants and assess their grinding operations to review and quantify improve- ment opportunities.


"We're making significant advances in the grinding indus- try toward that of cutting tools and we're obtaining material removal rates that are rivaling those of milling tools and inserts," said Gaffney. "This is being accomplished by the sharper grains and lower grinding forces, all with the ability to hold form and generate the consistent surface finishes required," said Finn. How does a user get the best grinding system available for his application? "In a perfect world, they come to our busi- ness development manager, work with our OEM department and the machine tool builders under a trilateral confidentiality agreement to develop a machining solution from scratch," said Finn. "If the machine and process are already set up, re- quest your local Norton representative to come in and assess your grinding system to evaluate the improvement opportuni- ties capable with the new Norton Quantum grain and the new Norton Vitrium3
