This testing machines are also well-suited for the calibra- tion of torque transducers or components and fi nished goods testing. This testing machines are available with suit- able grips and extensometers as well as high temperature furnaces for elevated temperature studies.

Torsional Tests can be carried out on most materials to determine me- chanical properties such as modulus of elasticity in shear, yield strength, ultimate shear strength, modulus of rupture in shear, and ductility. Also full-size parts as shafts, twist drills, and fasteners or components are subjected to torsional forces during their use that should be simulated in real-life service conditions. The frame of the testing machine features high torsional stiffness with low axial friction through rigid construction combined with ex- tra wide ball rail system. The high precision torque load cell is mounted on the movable crosshead that slides on the guide rail during the test. The grip that is mounted on the load cell can be turned fee ±270° by activating an electromechanical unclamping system to provide easy and torque free test set-up. The machine is driven by a high responsive servo- motor combined with a low backlash servo gear for excellent testing in both directions of rotation or intermittent torque loading. The servomotor is controlled though the dig- ital controller that allows close loop control of either angle or torque or can be turned by the digital hand wheel that is part of the controller. The test space is covered by a pro- tection device with electric switch for opera- tors safety. Suitable grip systems can be fi tted onto the Series LFM - T suitable to your testing re- quirements. Also available is a axial pre- loading system by a pulley arrangement and weights. No system would be complete without con- trol- and data acquisition software. DION ap- plication software package provides fully free user programmable testing, free controlling of testing machine and data acquisition of static, quasi-static, or cyclic applications. This package allows the simply programming of complex test sequences by structured Win- dows operation on a graphic user interface. 105 walter+bai Testing Machines Materials Testing Systems TORSION A B C D E F G H I J K L M N O P Q R S T Type LFM - T 20 50 100 200 Max.
