5.6. Punching mechanism, E machines
• The punching stroke is generated by a servomotor-driven mechanism.
• The upper and lower limits of the punching stroke can be set numerically (NC axis).
• In forming, the upper and lower limits of the ram are freely adjustable from the bottom position
up.
• With forming tools, you can program a lower ram speed and use a lower forming speed and a
positioning tolerance based on the G code, which allows making exact and intricate shapes.
5.7. Control centre
• The control centre accommodates the central processing unit of the NC control, the servo am-
plifiers, the cell control computer, and other electrical equipment.
• The computer in the control centre is equipped with a LAN connection.
• The NC control display, the main operation panel of the machine, and the touch screen are
located in a separate control desk.
5.8. Auto-index system
• The auto-index system enables automatic rotating of the tool in the working position according
to the numerical control.
• It is possible to perform punching strokes and nibbling with the tool at a freely programmable
angle.
• The system turns the tool automatically to the programmed angle while the X and Y axes of the
machine move the sheet.
• The index mechanism is mounted on the machine frame, due to which the index tool stations
in the turret are uncomplicated and interchangeable.
• A desired number of index tool stations can be mounted on the turret; the number of stations
can flexibly be changed afterwards.
5.9. Standard tool system Thick Turret
The standard tool system of a turret punch press is Thick Turret (AM). The turret punch press can
also be equipped with other tools to special order.
