Elcometer Taber® Abraser - Abrasion

The Unique Abrasion Process

A unique 'X' pattern of abrasion is produced by the rotary rub/wear action of the wheels. Wear action occurs as the wheels are turned by the rotating sample. An area of 30 square centimeters (4.5 square inches) is subjected to wear at any one time, and a complete circle of the material surface is abraded at all angles of grain or weave.

In order to customise the test to your requirements, choose from a wide variety of abrading wheels and abraser accessories to simulate real-life wear conditions.

 

Changing the abraser wheels and change the test! - Selecting the Abrading Wheels

The choice of abrading wheels for the Taber® 5135/5155 should be based upon the wear the specimen material will be subjected to in everyday use.

Taber® Abrading Wheels are available in five levels of abrasiveness to suit a wide range of material testing applications. Wool felt or plain rubber wheels test the delicate materials or the abrasiveness of matereials such as dental powders. Wheels which feature abrasive particles in a resilient matrix of rubber or a hard matrix of vitrified clay are suitable for stiffer materials.

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