DIAMOND & cBN ABRASIVES Diamond and cBN Wheels
Ideal wheels for wet or dry toolroom reconditioning applications
DIAMOND STOCK WHEELS • High quality synthetic diamond provides high material removal rates; longer wheel life vs. conventional green silicon carbide wheels • Pre-engineered resin bond – B99 for free cutting; superior form holding; efficient wet or dry

Wear resistant and thermally stable wheels that are great for resharpening
cBN STOCK WHEELS • cBN (cubic Boron Nitride) abrasive material is second in hardness to diamond which easily cuts difficult-to-grind
steel parts Rc 50 or harder and is highly wear resistant and thermally stable • Pre-engineered resin bond – B99 for free cutting, superior form holding • Premium Aztec III lubricating resin bond is most efficient for dry tool resharpening

TECH TIP
Cylindrical grinding applications – 1A1 wheels: • Includes all outside grinding of round parts, even though the finished product is not always a true cylinder. • Infeed at both ends of the traverse to keep wheel face flat. • Use work supports to prevent deflection. • Rough grinding traverse speed should be 1/2 to 2/3 of the thickness of the wheel per work revolution. • Finishing grinding traverse speed should be 1/2" or less per work revolution.
• Truing makes the wheel concentric with the spindle. • Dressing opens the wheel’s cutting face. • Always true and dress diamond and cBN wheels prior to use. It is the user’s responsibility to refer to and comply with ANSI B7.1
DIAMOND GRINDS: • Cemented carbide • Glass
cBN GRINDS: • High-speed tool steels • Die steels • Hardened carbon steels • Alloy steels • Aerospace alloys • Hard stainless steel • Abrasion-resistant ferrous materials
• Ceramics • Fiberglass • Plastics • Stone • Abrasives • Electronic components and materials
Cut-off applications – 1A1R wheels: • Use the largest diameter flanges possible • Use flanges of equal diameter • Use the thickest wheel possible for increased stiffness and straightness of cut
