Saw Head Frame
The Rigid ‘C’ section frame carries the
mountings for the two band wheels, heavy-duty
worm drive gear reducer, the band drive
motor,
and saw guide arm mounting supports.
Band Wheels & Drive System
The band wheels are cast iron for long,
productive life. The deflection free 1.38
inch
(35 mm.) wheel spindles ensure the wheels run
true regardless of tension stress or cutting
loads. The spindle assemblies incorporate
tapered roller bearings for greater rigidity
and
long service life. The wheel tracks the blade
so
that the back of the band is contacts the
wheel
flanges to support the band. The drive motor
is
coupled to the transmission through a
variable
speed pulley.
Drive Wheel Transmission
The drive wheel transmission is designed and
built by Amada to provide high efficiency
speed
reduction, which requires no external
cooling,
to deliver more power to the large diameter
drive shaft. This shaft ensures that this
developed torque is transferred to the blade
with no strobing, enabling the machine to
efficiently cut high alloys as well as free
machining materials.
Pressure/Flow Feed Control
The independent pressure and flow controls in
series ensure the optimum cutting rate can be
obtained regardless of section or alloy being
cut. The pressure control determines the
cutting
force applied to the blade and the flow
control
sets the maximum fall rate of the head. For
example for difficult to machine materials
the
pressure is set higher than free machining
alloys and the flow is set lower, as shown on
the escutcheons above the above the control
knobs.
Idler Wheel Motion Detector
The wheel motion detector will turn off the
blade drive in the case where a blade breaks
or
is jammed in the work piece. This feature
also
prevents premature wear on the drive wheel
from
a stalled band.
Automatic, Powered Chip Conveyor
The electrically powered chip conveyor auger
automatically removes the saw chips from the
saw
while draining the cutting fluid back into
the
fluid reservoir. The automatic chip conveyor
greatly reduces cleanup time and enables the
machine to run longer without operator
cleanup.
Multiple Index
The machine control has the capability to
make
up to 9 index passes giving a maximum cut
length
of 141.7 in. (3,600 mm.) in automatic.
Split Front Vise
The work holding vise is split so that it
clamps
the workpiece on both sides of the cutting
plane. This additional support in front of
the
cutting plane minimizes the burr on the cut
pieces. |
