Caltech Engineering Services offer Platform abrasion testing machine. Abrasion resistance test method is very old technique over 80 years and used for many applications. Abraser or Rotary abrasion test has been a popular method for accelerated evaluation of abrasion and wear resistance. Rotary abrasion tester is a cost-effective, easy to use and high quality instrument. Taber type abrasion tester is used to cover a wide spectrum of materials (including plastics, coatings, laminates, leather, paper, ceramics, carpeting, safety glazing, etc.With the rotary abrasion method, a rub-wear action (sliding rotation) is applied on the surface of the test piece and the abrasion marks create a pattern of crossed arcs in a circular band that cover an specific area. A key characteristic of rotary taber type abrasion tester (abrader abraser) is the abrasion wheels traverse a complete circle on the sample surface, showing abrasion resistance at all angles relative to the grain or weave of the material. We also provide wheels like CS-10, CS-17, CS-18 and more

For this method, a four-inch diameter specimen (flat, round or square shaped), normally less than () or 12.5mm thickness is mounted on a rotating turntable. Abrasive wheels are applied to the sample using a fixed weight. For a specified number of cycles, the abrasive wheels wear away the sample. Usually, two samples are tested. Taber abrasion machine result is calculated by measuring the weight loss cycles of abrasion. Abrasive wheels are commonly made of vitrified clay, and they come in a several levels of coarseness. The test procedure is to abrade specimens against a pair of grinding wheels under a specified pressure. Caltech Engineering Services offer rotary taber type abrasion tester, which is supplied with vacuum unit and has feature to trim automatically after selected cycles are elapsed. Abrasion Testing Machine gives best abrasion test results.
