216 / Bonded Abrasives BONDED ABRASIVES BONDED ABRASIVES PRODUCT SELECTION Vitrified bonds are the most common precision grinding bond. Porosity and strength of the wheels made with this bond give high stock removal along with their rigidity helping to attain high precision. Not affected by water, acid, oils or ordinary temperature variations. THE MOST COMMON VITRIFIED BONDS ARE: VS3 / VS3P VITRIUM 3 REVOLUTIONARY BOND TECHNOLOGY The Vitrium 3 bond platform features an exclusive chemistry that delivers an entirely new grain adhesion science, resulting in improved product versatility across a wide range of precision grinding applications. Provides cool cutting, precise profile, high speed, versatile across all precision grinding applications. VS VS is a versatile, low temperature, vitrified bond system used in most precision applications. VX / VXP Equivalent to VS bond, for ceramic only. VQN / VQNP These bonds are associated with Norton Quantum technology - a versatile technology for low, medium and high force applications.

The following rules should be followed: The grade indicates the relative holding power of the bond, which holds abrasive grains in a wheel. This is represented in the specification by letters running through the alphabet from softest to hardest. The following rules should be followed with regard to grade: USE COARSE GRIT • For soft, ductile, stringy materials such as soft steel or aluminium • For rapid stock removal • Where finish is not important • For large areas of contact. USE SOFT GRADE • For hard materials such as hard tool steels & carbides • For large areas of contact • For rapid stock removal. USE FINE GRIT • For hard, brittle materials such as hard tool steels, cemented carbides & glass • For fine finishes • For small areas of contact • For holding small corner radii. COMMON RANGE OF GRADES USE HARD GRADE • For soft materials • For small or narrow areas on contact • For longer wheel life. GRIT SIZE WHEEL GRADE
