AB-1150 LAMBOURN ABRASION TESTER

AB-1150 LAMBOURN ABRASION TESTER

Manufacturer: Ueshima – Nhật

Outline:

Among various abrasion tester for rubber such as tire, belt, and sole etc., it is Lambourn Type Abrasion Tester that is evaluated as the best reappearance in JIS K6264(Abrasion Testing Method of Vulcanized Rubber) as well as high correlation with the result of product test.

MODEL AB-1150 with high accuracy and stability invented in the method of load which has the largest influence on abrasion test result. As the result, high-performance & low-cost material tester which is available for direct simulation of quality test, was introduced to the field of tribology.

Feature

○The most suitable test condition to simulate the particular product such as tire, belt, roller, and sole etc., , can be selected.

○Instead of dead weight method for pressing force to the testpiece , feed back control method(Patent Pending) which is loaded by air cylinder and is detected by load-cell, is adopted. As a result , not only highly accurate and stable test condition can be obtained, but also bounding problem is solved by highly corresponding damping.

○Both rotating axis of testpiece and glindstone are feed back controlled independently by servo motor to test under conditions of more stable circumferential speed and slip ratio.
