Universal Sheet Metal Test Machine With Fully Automatic Test Sequence

Universal Sheet Metal Test Machine With Fully Automatic Test Sequence:
An extremely versatile test machine
for the medium to upper performance class ( 200
or 400 kN) which is suitable for applications in
the field of process control, but mainly used in
the research and development of new materials. The
machine is driven electro-hydraulically; the test
sequences can be controlled either automatically
or manually. The blanking press is integrated in
the test head; infinitely variable control of drawing
speed and blank holding force, independent of load.
Digital Display of drawing force, blank holding
force and punch displacement are shown with peak
value indication. Analog outputs or RS 232 C interfaces
enable force/displacement diagrams to be recorded.
As a further option, the control and regulation
of all main parameters and the evaluation of results
can be carried out via PC.
