TABER® Rotary Platform Abrasion Tester - Model 1700 / 1750

The TABER Rotary Stage Abrasion Testers include the Taber 5135 (single abrasive head) and Taber 5155 (dual abrasive head) models. First introduced in the 1930's, this precision instrument was developed specifically to perform accelerated wear testing and is widely used for accelerated wear testing. The Taber Abrasion Tester (Abrader) provides reliable material wear test data in a matter of minutes compared to actual use tests that can take years and has quickly become the global standard for evaluating wear resistance. Wide range of applications for abrasion testing of plastics, coatings, laminates, leather, paper, ceramics, carpet, glass and other materials.

The original Taber 5135, Taber 5155 has now been upgraded to Taber 1700, Taber 1750.

In the automotive industry, the Taber is widely used to evaluate the abrasion resistance of paint, clearcoat and plating.
Principle: Long-term wear is simulated by rotating a specimen and applying a load to the friction surface with a specific abrasive wheel (e.g. CS-10 or H-18).
Standard: ASTM D4060, ISO 7784, etc.
Applicable scenarios: Paint testing of door handle areas and high frequency contact areas.

Taber abrasion gauges have been used for quality and process control, research and development, and materials evaluation since their inception. The instruments can be used to test a wide range of materials and are referenced in numerous standards and specifications (including plastics, coatings, laminates, leather, paper, ceramics, carpet, safety glass, etc.).

The Taber test involves mounting a flat specimen of approximately 100 mm (square or round) on a turntable stage that rotates around a vertical axis at a fixed speed.The standard material thickness that can be tested with the Taber Rotary Abrader is 6.35 mm (materials greater than 6.35 mm but less than 40 mm can be tested with the optional accessory). Two Taber original grinding wheels are pressed against the specimen surface at a specific pressure.

The characteristic frictional wear action of the Tabor test chart is produced by sliding rotational contact of the specimen with two abrasive wheels. As the turntable rotates, the specimen drives the abrasive wheels in opposite directions around a horizontal axis tangential to the specimen axis. One abrasive wheel rubs the periphery of the specimen outwardly toward the outside, and the other abrasive wheel rubs inwardly toward the center, while a vacuum system removes loose debris during the test. The abrasive wheels make a full circle around the surface of the specimen, showing the abrasion resistance at various angles relative to the weave or texture of the material. The resulting wear marks form a pattern of crossed arcs in a circular band covering an area of approximately 30 cm2.

Each turntable is equipped with precision balanced double grinding arms. The arms are independently operated and can be raised and lowered to mount or inspect specimens. Each arm is precision balanced to apply a load of 250 grams to the specimen (not including the weight of the grinding wheel). To increase the load to 500 or 1000 grams, an auxiliary weight can be mounted on the outside of the grinding wheel bearing assembly. This location ensures that the weights are concentric with the grinding wheel. 1700/1750 models are available with an optional weight kit to reduce the load. For older Taber grinders, a stud on the back of the grinding arm can be used to carry an optional counterweight. All models use counterweights to reduce the load by 50, 125, 150 or 175 grams.

Taber Abrasion Models 1700 or 1750 have the following standard features:

The sample carousel speed control allows selection of 60 rpm and 72 rpm.
Easy-to-use LCD operator touch screen interface with selectable display options (including language selection).
The vacuum system is included and is critical to the proper operation of the instrument. The DC vacuum nozzle is hinged on an adjustable bracket at the rear of the housing. The nozzle consists of two 8 mm diameter screw-in nozzle tips (11 mm nozzle tip sold separately). A precision vacuum nozzle adjustment controller allows height adjustment to accommodate different sample thicknesses.
The compact grinding arm assembly applies a standard load of 250 grams to the grinding wheel. With the use of an auxiliary weight, a standard grinding wheel load of 500 or 1000 grams can be obtained. Please note that the markings on the auxiliary weight do not reflect the actual mass of the additional weight. The auxiliary weight is marked with the total load applied to the wheel, which is equal to the total mass of the grinding arm and the auxiliary weight. A counterweight marked with 500 grams is actually 250 grams and a counterweight marked with 1000 grams is actually 750 grams.
Quick Removal Mounting Hubs allow quick mounting of the wheel without locknuts, increasing the mounting space for the vacuum nozzle and expanding the viewing area of the specimen. Spring-loaded angled locknuts provide positive locking force on the hub retaining lip, ensuring that the wheel remains securely fastened until removal.
Each sample stage includes a separate support frame to which the wear arm and nozzle assembly is secured.
