Dual Drive System
Different from conventional servo hydraulic mechanisms which
continuously control high-speed movement and pressure movement of the
ram, the Dual Drive System separately controls high-speed up and down
movement by AC servo motor and ball screw drive and hydraulic pressure
movement. By the Dual Drive System, high-speed downmovement at 200mm/sec
and stable repeat-stop accuracy by AC servo motor and hydraulic drive
are enabled, realizing high productivity. In addition, the Dual Drive
System is superior in total energy saving because it is fitted with a
assist device that stores the energy of down movement and returns it
during ram up movement.
High speed Ram stroke with AC servo motor and ball screw drive.
High quality stop accuracy by hydraulic mechanism.
Ecology operation by assist device.
Ideal Curve Crowning System
The Ideal Curve Crowning System is created by conducting FEM analysis
of the frame in pursuit of the ideal correction curve with respect to
crowning which becomes a problem for the press brakes. Simple and fine
adjustment is enabled with use of a monoaxial curving wedge. Automatic
crowning adjustment is made quickly for each bending step without
stress.
