FUNCTIONS
This machine is a press brake whose lower beam is hydraulically raised by the linear
servo valves at the right and left sides. The UP and DOWN foot pedals are pressed to
move up and down the lower beam. The punches are mounted in the punch holders
attached to the upper beam, and the dies and die holders are mounted on the lower beam.
The worksheet is laid over the dies, supported by hand, and bent by raising the lower
beam onto the punches. The bend angle of the worksheet depends on the clearance
between the dies and punches. The lower beam is moved up and down by the main
cylinders installed on the right and left sides. The auxiliary cylinders are installed at the
center of the lower beam to prevent a long worksheet from being bent with a greater angle
toward the center (or to keep the clearance between the upper and lower beams uniform
in the longitudinal direction). The bend angle is finely adjusted by the right and left linear
servo valves, which can also be controlled independently to tilt the lower beam. This
tilting function allows the difference in the bend angle between the right and left sides of
the worksheet to be compensated for and the worksheet to be offset bent (or bent off the
center of the machine). The worksheet can also be pushed against the stoppers of the
backgauge to determine its bend position. The machine can be operated from the NC
control box.

Coordinate system of axes
Basically, the machine is controlled by the D1, D2, L1, L2, Y1, Y2 and Z axes and CC
value.
D1 axis: Axis along which the left main cylinder of the lower beam moves up and down
D2 axis: Axis along which the right main cylinder of the lower beam moves up and down
L1 axis: Axis along which the backgauge moves back and forth on the left ball screw
L2 axis: Axis along which the backgauge moves back and forth on the right ball screw
Y1 axis: Axis along which the left backgauge moves left and right
Y2 axis: Axis along which the right backgauge moves left and right
Z axis: Axis along which the backgauge moves up and down
CC value: Pressure of the auxiliary cylinders in the lower beam

* When the temperature of the hydraulic oil is low, the lowering speed of the lower beam is
reduced to 60 mm/sec (2.36 in./sec) to prevent the machine from malfunctioning.
When the hydraulic oil returns to the normal temperature, the lowering speed of the
lower beam returns to 90 mm/sec (3.54 in./sec).

BACKGAUGE
One-touch stopper fingers
The stopper fingers can be changed by one-touch. Change the stopper fingers to
suit the shape of work, etc.
For changing the stopper fingers, refer to “Installing stopper fingers” in Part II,
Installation.
The end positions and the NC displays of the standard stopper fingers and stepped
stopper fingers are as shown below.
NOTICE
● When the backgauge is to be used close to the punches, take care so that the stopper
fingers do not interfere with the punches that move as the worksheet is bent.

I-1
Worksheet overhang
The backgauge can place a worksheet on the straightedge.
Load capacity: 20 kg.
Gently place the worksheet on the straightedge so that no shock is applied to the
straightedge.
NOTICE
● When the weight of the worksheet exceeds its load capacity, the straightedge may dorp
down. In such a case, the worksheet may spring upward or slip downward as shown below.
Be sure that the worksheet weight does not exceed the straightedge load capacity.
