Product Description

Taber® Grinding Wheels are available in many levels of abrasiveness to suit a wide range of material testing applications.

The choice of abrasive media should be based upon the wear the specimen material will be subjected to in actual use.

Wool felt or rubber wheels are used to test delicate materials. Wheels of abrasives in a matrix of rubber or vitrified clay are used for other materials.

Abrading wheels for Taber® Abrasers include five general types of varying abrasive quality:

  • Calibrase® — a resilient wheel composed of rubber and aluminum oxide abrasive particles;
  • Calibrade® — a non-resilient wheel composed of vitrified (clay) and silicon carbide abrasive particles;
  • Wool Felt — no abrasive particles;
  • Plain Rubber — no abrasive particles unless used with sandpaper strips;
  • Tungsten Carbide — extremely severe cutting and tearing action with helical teeth for use on resilient materials such as rubber, leather or floor covering.
