Norton 57A Centerless Wheels are made using strong, blocky-shaped
aluminum oxide in a vitrified bond. This versatile/durable abrasive is
well suited for general purpose applications, featuring high “G” ratios
(metal removed/wheel wear). The superior vitrified bond system offers
longer wheel life, with excellent form holding.
Norton 64A Centerless Wheels feature versatile aluminum oxide abrasive
blend in a vitrified bond, engineered to grind a variety of materials at
an economical price. The specially blended aluminum oxide abrasive
coupled with a superior vitrified bond will maintain high grinding rates
without wheel breakdown.
Centerless grinding is a production process that produces extremely
close tolerances on metal cylindrical forms or parts. Centerless
grinding is used on a wide variety of workpieces. The key components in
the process are the grinding wheel, the work rest blade (used to support
the work), and the regulating or “feed” wheel (the drive mechanism for
