WDW-10E / 20E computer-controlled electronic universal testing machine
The machine is mainly used for tensile, compression, bending and other conventional performance tests of metal and non-metallic materials, measuring performance parameters such as R P , R t , R eH , ReL , R m , E, Equipped with the corresponding accessories, but also according to GB / T5027 and GB / T5028 metal sheet plastic strain ratio (r value) and hardening index (n value) test; according to GB / T4338 high temperature tensile test.
Host using a single desktop space, the framework for the double-column double-spine door structure. Speed ??control system installed in the lower part of the workbench , the next space to do stretching, compression, bending, shear test (test space can be customized according to customer needs into a double space). Beam steplessly. Transmission part of the arc synchronous toothed belt, screw pair transmission, transmission smooth, low noise. Specially designed synchronous toothed belt reduction system and precision ball screw drive the moving beam of the testing machine to realize the gapless transmission. Import AC servo drives and AC servo motors, stable performance, reliable, with over-current, over voltage, speeding, overload and other protective devices.
Feature
GB / T228 "Tensile Test Method for Metallic Materials at Room Temperature"
GB / T7314 "Metallic materials at room temperature compression test method"
To meet GB, ISO, ASTM, DIN and other standards. According to customer needs to increase other appropriate standards.
