Sheet metal testing machine ERICHSEN
1000 kN

Universal Sheet Metal Testing Machine for Research, Development and
In-process Testing, Model 146-60/100

The special feature of this testing machines is the increased drawing speed of the drawing punch which, in addition to the normal drawing speed range of 0 - 1,200 mm/min can be adjusted, in an infinitely variable manner and independent of load, up to 3,000 mm/min. This is achieved by using a separate oil circuit, fed by a pump with high volumetric displacement. Contrary to the high speed attachment based on a nitrogen accumulator, here a constant drawing speed behaviour is guaranteed over the total displacement of 150 mm. As to the technical design and the options available, including PC control and proportional valve technique, this machines are similar to Models 145. The basic version of the machines includes an oil/water cooling and have a power consumption of 45 kW.
