Wire abrasion tester

SR-1024

Wire abrasion tester, intercept samples of six 40in or 1000mm long line-shaped specimen from the finished wires or cords. Specimen without dealing with the directly doing the test. equipment and sample should be in thermal equilibrium with the surrounding temperature in the 23.0 ± 5.0 Degree (73.4 ± 9.0 ) during the trial period.. Testing material fixed on the jig and another hanged load, the surface of testing material contact with the grinding wheel, grinding wheel to rotate clockwise, when the rotation reach the set amount, Check tear or the conductor is exposed or not.

Features

When a horizontal reciprocating motion test-bed at the end of its journey, it will be received at one end of each specimen in the test rig. The other side of each specimen shall be fastened with a 4.0 ± 0.5 ozf may be imposed, or 1.1 ± 0.1N or 113 ± 13gf the weight force. Each sample should be placed in a fourth column, circle the outer surface of living without the use of a paste 1 / 2 size (medium) emery cloth. emery cloth surface of the radius of curvature should be 3.5in or 90mm, cylindrical level and the vertical axis should be adopted with each trial (when they are moving forward and are subject to emery cloth friction) and vertical plane perpendicular to.
Test-bed should be 28 cycles per minute, the speed began his level of reciprocating motion (simple uniform motion), each loop including a complete and reciprocating stroke 6-1/4in or 160mm, after 50 cycles for each test-bed so that only movement . emery cloth and then move a little towards the side, so that after each cycle of the new specimen will be subjected to emery cloth surface friction. If the 400 or less friction cycle, six samples of any part of any one metal Single nudity,then the wire or soft wire will failed.
