| The NexTOP Ultrahigh Load
Press is mainly composed of yoke, press frame, press
tables such as ram and bolsters. A unique feature of
the press is such that unlike general presses wire-winding
technology is employed to the NexTOP Press. High strength
steel is wound by multiayer around the yoke and column,
which is subjected to tension. Therefore, the press
frame under severe compressive force generated by wires
of multilayer can withstand extremely high press load.
In practice press load does not exceed the pre-stress
of the frame, preventing its deterioration by fatigue.
Also, the wire-wound press is much smaller and lighter
in volume, safer and stronger in comparison to other
presses due the fact that the wire-wound frame under
pre-stress makes it possible to drastically increase
the maximum load capacity resulting in minimizing the
frame structure in weight. |
