Main Structure, Function and Application Range：

The torsion test machine is mainly used for determination of diameter φ0.3-φ1mm, φ1-φ3mm, φ3-φ10mm metal wire in the one-way or two-way reverse the ability to withstand plastic deformation during the test can show wire surface defects. Mainly applied scientific research departments, industrial and mining enterprises and institutions used to determine the mechanical laboratory torsional properties of materials, particularly suitable for production line testing and the use of flat wire cable unit purchase inspection. torsion test machine with 2-3 kinds of rotation speed to choose from, such as 30, 60, 90, 120, 180, 300 / min, through the belt pulley adjustment; to clamp wire length 300-100mm, 500 - 300mm; with a pulley driven weights and axial force, liquid crystal display test laps, after the test specimen and automatically latch ring value.
