It is designed in the style of metal strip drawing tests. The test rig consists of a pneumatic normal force unit and a servo-electric draw unit. The normal force is applied by four structurally identical pneumatic cylinders and can reach up to 6.6 kN at a pressure of 10 bar. With a testing area of 40 mm x 40 mm, a contact normal force of about 4 N/mm2 is generated. The accuracy depends on the proportional regulation valve and is +/- 0.00625 N/mm2 at the maximum.
With the servo-electric linear axis, a relative speed of up to 350 mm/s with an acceleration of 27 mm/s2 is accessible. For the investigation of the influence of temperature, the test area can be heated up from room temperature up to 200 °C.
