Radius Edge CBN Wheels
What is CBN?—Cubic boron nitride (CBN) is a synthetic chemical compound made up of boron and nitrogen atoms in a one-to-one ratio. It exists as a cubic crystal lattice, with its atoms arranged in a symmetrical, cube-shaped structure like the crystalline structure of diamond. Its material properties include extreme hardness, stability under heat, and superior chemical resistance. Cubic boron nitride is the second-hardest known material after diamond, making it useful in a wide variety of industrial applications, where it is often used as an abrasive or cutting tool.
The heat resistance of CBN is quite high. Diamond begins to decompose to carbon dioxide in air at around 1,472°F (about 800°C), whereas cubic boron nitride is stable in air up to about 2,552°F (about 1,400°C). In industrial grinding applications and other processes where intense heat is generated, CBN is preferred over diamond. (wisegeek.com)
to come off but finally I removed them and cleaned up some rust on the shafts. One wheel needed to
remove the inner washer to run smoothly but now they are both running perfectly. First time ever I've
had a grinder run smooth like that. Love the lamp too, tons of output with no heat."
Thanks so much for excellent products. -Ed
I received my new CBN wheels today. These things are better than sliced bread. I have always had
trouble sharpening my tools until today. It was like coming out of the dark ages.
