Taber Linear Scratch Testing with Reciprocating Abraser

The Taber Reciprocating Abraser includes a counterbalanced arm which pivots on an adjustable height gantry system. The counterweight allows the user to balance the test arm, ensuring precise test load set-up regardless of the weight of the attachment. Incorporated at the end of the arm is a tool holder to which optional attachments and weights may be secured. A sliding specimen platform moves in a horizontal, reciprocating motion under the stationary tool holder.

Reciprocating abrasion tester used by way of rotary grinding, using different kinds of friction wheel rotational friction on the sample to detect wear performance for leather and plastic materials, make scientific evaluation of the wear resistance on the product.

Depending on the type of material under evaluation, the visual appearance of a scratch or mar normally involves changes in surface topography, color, or brightness.  Three methods are normally used:

Visual Evaluation - Scratch resistance is normally reported as the minimum load necessary to penetrate the surface of the specimen. The observer increases (decreases) the testing load until the point when a visible line is scratched on the specimen surface. This line should penetrate the surface and not be able to be wiped off.  It is also possible to rank scratches based on an existing standard. A standard numeric rating representing 3 to 5 increasing scratches (or what constitutes a Pass / Fail) may be established for each type of material and used solely for comparison to determine test end point.

Test products are fixed at the level of the table, in the abrasives and load with the movement of the provisions under the level of water for the station being worn; The use of the principle of leverage, the other end of the arm with the test weight to maintain balance test arm to ensure the reliability and accuracy of the sample surface load test results.

Abrasives and load frame height is adjustable to be suit for different height of the sample tested. According to the different requirements of customers, the use of different media to test different products friction abrasion resistance.
