On 3M™ Vitrified Grinding Wheel 22VD, the surface of the grain/bond compound is improved using self-organizing nano surface structures that practically eliminates cold bonding of the chips and other types of clogging. As a result, the grinding wheel retains its free-cutting ability during the processes, requires less drive power from the machine, and achieves consistent surface structures on the workpieces without creating grinding burn. 3M 22VD contains aluminum oxide nitride abrasive grains.

• Minimal risk of grinding burn
• High thermal stability and wear resistance
• Low wettability, and thus significantly fewer built-up edges
• Higher removal performance
• Constant surface finish qualities
• Less mechanical deformation of workpieces
• More tightly controlled process conditions
