EZ series wire rod torsion testing machine is made according to the technical requirements of BG / t239-1999 wire rod torsion test method. It is a new type of wire rod torsion testing machine with digital display and counting developed by our factory. The testing machine has three rotation speeds: 30; 60; 120 rpm, mainly used for torsion test of 00.1mm ~ 20.0mm metal wire. It is used to measure the ability of metal wire to withstand plastic deformation in unidirectional or bidirectional torsion and the surface and internal defects of wire. It provides a reliable measurement means for the production and use of wire rod.
