CBN is superior to all other materials for grinding hardened steelwhichwidelyused in most of today's modern turning tools.Unlike traditional aluminum oxide grinding wheels,MoresuperhardCBN Sharpening Wheel cuts fast, stays cool and never needs dressing or shaping. With only a very light amount of pressure when sharpening and proper care, you can sharpen your tools to a razor sharp edge and never need to buy another sharpening wheel again.

What is CBN?

CBNis an acronym for Cubic Boron Nitride, which was originally developed by General Electric Company. CBN is more costly than industrial diamond, is nearly as hard as diamond and4 times harder than aluminum oxide thus revolutionizing the grinding of hardened steel.

Why is CBN superior to diamond for sharpening turning tools using a bench grinder?

Diamond is chemically pure carbon. When used as a grinding grit, it works extremely well with tungsten carbide or glass. With hardened steel on a grinder, this is a different matter altogether. When used on a bench grinder at common speed, the diamond (carbon) reacts to ingredients in the tool steel, which causes the diamond to break down which in turn ruins the wheel.

How isMoresuperhardCBN Sharpening Wheel made?

MoresuperhardCBN wheel consists of a precision machined, solid steel body coated with an electroplated layer of CBN abrasive grain. The CBN grain is only a few thousandths in diameter and will last a lifetime with proper care.

Why is CBN superior to Diamond for sharpening turning tools?

Diamond is a pure carbon that works very well with carbide and glass. With hardened tool steel, it's different matter. Diamond reacts chemically with hardened tool steel during high speed grinding. This chemical reaction causes the diamond particles to become dull and unable to cut efficiently. CBN particles stays sharp, won't break down when sharpening, and let you utilize traditional grinding equipment for sharpening your turning tools.

How is sharpening onMoresuperhardCBN Wheeldifferentfromusing aTraditional Grinding Wheel?

Use Only Light Pressure-When sharpening with the CBN wheel, use only very light pressure as this wheel cuts very fast. Too much pressure against the wheel will generate excessive heat that will damage the wheel.

Operate at a Lower Speed-To improve control while sharpening, operate your grinder at a slower speed. 1,100 to 2,200 rpm is recommended.

For Hardened Tool Steel Only-CBN wheels should only be used on hardened tool steel and tungsten carbide. Never grind carbon steel, aluminum or other soft metals as it will cause permanent damage toMoresuperhardCBN wheel.

Make Your Wheel Last A Lifetime-Be careful not to strike the wheel with a tool or object as the impact could break CBN particles free, causing permanent damage to the wheel surface.
