The Series TTM® Testing Machines are state-of-the-art, rugged and durable designed especially suitable for high capacity testing of round, flat and profile specimens meeting the needs of the metals, aerospace, automotive and fastern industries. Available in two or four column construction capable to provide accurate, repeatable and reliable results for tensile, compression, flexure, peel, shear, tear or friction tests on a wide range of different materials for quality control, product development, research or process development. Wide Range of Application:
Testing systems for brittle materials such steel or fasteners requires high stiffness load frames that minimize the amount of deformation energy that is stored in the frame. Its essential to minimize the released energy from the frame for minimum maintenance and low reaction at specimens failure. With this in mind all models of the TTM® family features high rigid load frames either in two or four column construction with superior axial and lateral stiffness and precision aligned for advanced static testing. To meet the wide variety of testing needs of laboratories and manufacturers in the field of metals, automotive, aerospace, fastener a.s.o industries w+b offers the TTM® in different configurations. This Testing Machines are available with the universal testing software DIONSTAT which provides most EN, ISO, DIN or ASTM and other standards tests.
Features: rigid 2- or 4-column-construction providing superior axial and lateral stiffness and precision aligned Single workspace-design with convenient working height Double acting servo-actuator mounted on top of the crossbeam Long piston stroke for the most convenient and easy adjustment and testing of different sample lengths Upper crosshead movable to increase distance between grips Actuator with anti-rotation system to prevent the natural tendency of the actuator to rotate Servovalve attached direct on actuator providing close-coupled servovalve and accumulators for improved performance and reduced pressure fluctuations With digital displacement transducer for the best positioning and measuring accuracy With chrome plated columns for easy cleaning and longest life Manual or hydraulic operated wedge or parallel grips available Including grip control system mounted direct at the machine Compression platens or bending / folding devices may be fixed directly into wedge grips.

The servoactuator, which is integrated in the upper crosshead, having a long piston stroke makes testing space accessible for easy and efficient testing of different samples lengths. The long piston stroke meets the extreme requirements of international standards without changing the crosshead adjustment. On piston rod end a anti-rotation system prevents the natural tendency of the actuator to rotate. All TTM® Testing Machines are equipped with ah high resolution (0.82 µm) digital displacement transducer for accurate and reliable closed loop position of actuator, piston stroke control and measurement. The manifold is attached direct on actuator providing close-coupled servovalve and accumulators for improved performance and reduced pressure fluctuations. The Moog-Servovalve features high force level permanent magnet linear force motor directly driving the spool. A LVDT is attached to the spool to provide spool position feedback. An internal loop is closed around the spool position. The valve provides additionally low hysteresis and low threshold, low current consumption at and near hydraulic null, standardized spool position monitoring signal with residual ripple, electric null adjust and with loss of supply voltage or broken cable or emergency stop, the spool returns to its spring centered position without passing a load move position. The precision load cell is located between base platen and lower grip, providing high accuracy test after test. The load cell additionally features excellent repeatability, compact design, low temperature drift and accessible mounting. Ergonomically design with unchanged height of lower grip and accessible test space for easy and efficient testing. With chrome plated columns for easy cleaning and longest life. The TTM® Testing Machines can be installed on factory-floor without require any special foundation. Standard delivery includes pads which can be put between machine and floor.
Upper Crosshead:
As standard TTM® features mechanical movable upper crosshead but are also available with fixed or automatic unlocking and hydraulic adjustable lift system.
