Quantum Prime grinding wheels include a proprietary nano-crystalline ceramic grain that offers productivity gains across a wide range of applications. The Quantum Prime grain delivers exceptionally high grinding efficiency and part quality and significantly longer wheel life than traditional ceramic grains. The grinding wheels have several important advantages, including a new micro-fracturing grain that has unparalleled sharpness and cutting efficiency, which reduces power draw and cycle times while increasing material removal rates. The unique grain is free-cutting, which allows Quantum Prime to wear more consistently to improve part quality, geometry and finish even at high material removal rates. Quantum Prime also has a more friable self-sharpening grain technology, so grinding wheels stay sharper longer, which reduces dress requirements and drastically improves wheel life.
