Taber's model 1700/1750 provides the same rugid features as previous versions. The characteristic rub-wear action of a Taber Test is produced by contact of the test specimen against the sliding rotation of the two Genuine Taber abrading wheels. As the turntable rotates, the wheels are driven by the sample in opposite directions about a horizontal axis displaced tangentially from the axis of the sample while a vacuum system removes loose debris during the test. The wheels traverse a complete circle on the specimen surface, revealing abrasion resistance at all angles.
