Scrape Abrasion Tester For Testing Lab

Scrape Abrasion Tester - For Testing Lab The  Scrape Abrasion Tester for Automobile Cables consists of a scraping wire, which abrades the test specimen under a fixed load of 7 N and a suitable mounting platform for clamping the test specimens on.   The scraping wire is in form of a round spring wire with a diameter of 0.45 mm, and secured rigidly to a carrier. Motion to the carrier is given through an oscillating arm, which runs on grease sealed type ball bearings minimizing friction and giving uniform load on the carrier. The oscillating arm is moved with the help of a motor operated crank and connecting link to give a total stroke length of 20 mm. An arrangement is provided to lift the carrier at both the extreme ends of the stroke. A low voltage supply system with relay is provided to automatically stop the motor as soon as the scraping wire comes in contact with the core of the specimen under test. A pre-set type four-digit electronic counter with memory backup is provided to record the number of strokes and also to stop the motor automatically after a pre-set number of strokes. civil lab equipments manufacturers
