Taber H-22 Calibrade Wheels
Genuine Taber abrading wheels for the Taber Abraser are available in two general types, Calibrase and Calibrade®. With standardized grades to meet varying requirements of abrasive action, numerous types of materials may be evaluated. Custom abrasives can also be developed, specific to your application.
For both Calibrase and Calibrade wheels, different grades are furnished to meet varying requirements of abrasive action. The composition of Genuine Taber abrading wheels has been carefully chosen to reproduce normal service wear. The quality and uniformity of these wheels is maintained by continuous inspection sampling and tightly controlled manufacturing processes.
H-22 Calibrade - The H-22 wheel produces a coarse abrasion. It has been used to test rubber, linoleum, leather, deep pile fabrics (such as automobile floor coverings) and concrete.
H-18 Calibrade - This commonly used non-resilient wheel provides a medium coarse abrasive action. It is most often used to evaluate resilient materials such as rubber (non-tacky), certain woven textile fabrics, coated fabrics, and flexible plastic sheets.
H-10 Calibrade - A non-resilient, vitrified wheel designed to evaluate steel and ferrous alloys for resistance to abrasion. It has also been used to test the effect of hardening and tempering treatment on steel and other ferrous materials.
An essential component of conducting "Taber wear tests" is the type of abrasive wheel that is used. Taber offers standardized grades of Genuine Taber abrasive wheels, engineered for a variety of specific applications. The wheels are a proprietary formulation developed and designed by Taber Industries so the binder material breaks down during use, exposing and creating a new abrading surface. The minimum usable diameter of Taber abrading wheels is 44.4 mm, which corresponds with the wheel label.
Abrading wheels for the Taber Abraser (Abrader) can be classified as:
Calibrade - A non-resilient wheel composed of a vitrified (clay) binder and silicon carbide or aluminum oxide abrasive particles. Frequently used to evaluate flexible specimens.
Calibrase - A resilient wheel composed of resilient binder and aluminum oxide or silicon carbide abrasive particles. Frequently used to evaluate rigid specimens.
Taber abrading wheels produce characteristic rub wear action
Used with the Taber Rotary plateform Abraser, two abrasive wheels create the circular wear path reconized as a Taber test. As specimens are subjected to the rub wear action of the wheels, the abrasion marks form the pattern of crossed arcs resulting in a circular ring. This process abrades the sample over all angles of grain or weave, and covers approximately 30 square centimeter.
Analytical Grade abrasive materials ensure Test repeatability
The composition of Taber abrading wheels has been carefully chosen and a rigorous quality program maintains the uniformly of the wheels. Used in Pairs, each wheels is labeled left or right to assure the mounting position will be duplicated should the wheels be removed and later reinstalled. The wheels should be refaced according to recommanded practice, and can be used to their minimun usable diameter of 45mm O.D.

Composed of a resilient binder, and aluminum oxide or silicon carbide abrasive particles. During testing, the wheel surface wears away to expose new grain particles.
Calibrase wheels are often used to test rigid specimens, Calibrade wheels to test flexible specimens.
Under ordinary conditions, a wheel / load combination should run a minimum of 100 - 300 cycles on a material specimen before the end point occurs. Otherwise, the test may be too harsh.
The minimum usable diameter of Taber abrading wheels is 45 mm (1.75”), which is the same diameter as the wheel label. Wheel life is dependent on load, frequency and method of refacing, and material being tested.
During testing, wheel surfaces may “clog” or “crown” and require refacing.
Increasing the load on the wheel typically increases the rate of wear.
Most published test methods provide sufficient details on which abrasive wheels to use. If you are following a particular standard, please refer to it for the appropriate wheel. If your application is not covered by an established procedure, deciding which abrading wheel is best determined with preliminary testing on the actual material. The ideal selection criterion is to reproduce, as nearly possible, the wear which the material will be subjected to in actual use.
