Machine Overview
1.1 Introduction
This chapter overviews general information on the Bend-Tech Dragon A400. This general
information is a starting point to learn about the Dragon A400. For detailed information on
operation and troubleshooting, please refer to your Bend-Tech Dragon A400 Operator’s
Manual.
1.2 Gate Overview
The gate is located at the front of the Dragon A400. The gate works in conjunction with the
chuck to support and move the material through the cutting process. There are two styles of
gate that the Dragon A400 can come equipped with: a non-powered gate and a powered gate.
Gate Type Function
Non-Powered Gate Round, square or rectangle material. Does not support
angle or channel
Powered Gate Round, square, rectangle, angle or channel material.
Essential when processing angle or channel.

1.2.1 Gate Eccentric Bearing
The gate rides upon three bearings located on the
back face of the gate assembly. The gate should ride
smoothly on its bearings with no binding. If there is
play in the gate or if the gate binds while moving,
the gate eccentric bearing may need adjustment.
Please, contact customer support before adjusting the
eccentric bearing.
A Dragon A400 machine equipped with
a Non-Powered Gate will not have a
C-Axis drive motor or ring gear.
A Dragon A400 machine equipped
with a Powered Gate will include
the C-Axis drive motor and
Powered Gate Ring Gear.

Important
Keeping the gate clean is key to maintaining optimum performance of the Dragon.
Refer to maintenance guidelines for the gate for cleaning procedures and intervals.

1.2.2 Gate Lead Screws
The lead screws are used to adjust the opening of the gate. The gate uses two lead screws,
positioned 90 degrees from each other. Adjust the lead screws using a ¼ in. Allen wrench,
which is provided with the machine. Turning the lead screws clockwise closes the gate, and
turning them counterclockwise opens the gate. The gate lead screws should operate smoothly
with minimal force and no binding throughout the travel.
1.2.3 Gate Adjustment
When loading material, the gate should be adjusted so
that the rollers are snug against the material. The rollers
should not be overtightened, and should spin by hand, but
not spin freely. The material needs to move freely within
When no material is loaded into the gate, the gate rollers
should spin freely without binding or sticking.
1.2.4 Gate Clamp
The gate clamp is used on non-powered gates to
lock the gate into one position. It is used only for
round stock. The gate clamp is critical to keeping
round stock in position during cutting. Always lock
the gate with the lead screws in the 12 o’clock and
3 o’clock positions.
1.3 Material Support Lift Overview
The material support lift is used to support extremely long or thin material. Long material can
support lift can accommodate up to 6-inch OD round stock or 4-inch diameter square stock. By
default the material support lift will activate for material stock over 10 feet (3 meters).
Important
The gate will only need
to be adjusted when
changing material types
or sizes, or for removing
remnant material.
Reminder
Machines equipped with the powered gate
do not come equipped with a gate clamp.

1.3.1 Material Support Lift Operation
The material support lift is
powered by the B-Axis motor
which moves the lift up and
down. The rotation of the
material support lift is achieved
via a pneumatic cylinder.
The pneumatic controls for
the material support lift are
pre-set to 60 psi. However,
line pressure going into the
of operation of the material
support lift so some adjustment
may be necessary.
1.3.2 Air Cylinder Adjustment
The speed of the material
support lift rotation is controlled
by a needle valve adjustment screw on either
end of the air cylinder. The right side needle
valve adjustment controls the inward rotation
of the material support lift (toward the Rail).
The left side needle valve adjustment controls
the outward rotation of the material support
lift (away from the Rail).

Important
When adjusting the
needle valves on the

cylinder it is best to turn
them ¼ turn at a time to
avoid over adjustment
and possible damage
to the assembly.
