Refacing for Optimal Abrading Wheel Performance
As Genuine Taber® abrading wheels are used, they slowly disintegrate exposing fresh abrasive grains. When testing certain materials however, the wheel faces may become clogged as a result of the adhesive character of particles worn off the specimen. This changes the abrasive characteristics of the wheel and may impact test results. To reduce this variation, the working surface of abrading wheels must be cleaned and refreshed prior to use and if necessary, at regularly defined intervals. This process is referred to as refacing.
Recommended Refacing Media
Different Taber wheel types require specific refacing media for optimal performance. We do not suggest refacing CS-0 (rubber), CS-5 (felt), S-35 (tungsten carbide) or S-39 (leather) wheel sets as attempts to do so may damage the wheel.
Calibrade® Wheel Refacing (Vitrified Type)
The Taber® Wheel Refacer – Model 350 allows you to true and completely renew the working surfaces of Taber abrading wheels. Wheels are secured to a flanged extension of the motor shaft, and enclosed by a hinged cover for safety. A diamond tool, mounted on a shielded traverse slide, permits light cuts across a pair of wheels providing identical wheel diameters. Calibrade® wheels such as the H-10, H-18 and H-22 are diamond trued before leaving the factory and should be refaced whenever they show signs of being out of round, crowned or clogged with abraded material.
Calibrase® Wheel Refacing (Resilient Type)
Calibrase wheels such as CS-10 and CS-17 are typically refaced with the S-11 Refacing Disc. The S-11 refacing disc is a 4″ diameter, 150 grit abrasive paper sold in packages of 100. When using CS-10F wheels to evaluate transparent materials, the ST-11 refacing stone is used to resurface the wheels. The ST-11 refacing stone is a vitrified product that is 4″ diameter x 1/4″ thick with a 1/4″ center hole, manufactured with 180 grit surfaces.
