Band 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 Saw 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. |
Wide Blade (1¼ inch, 34mm) |
The wider blade, for this capacity machine, can make full utilization of
the large band drive motor (5 hp, 3.7 kW) when cutting all shapes and
alloys. |
Drive Wheel Transmission |
The drive wheel worm gear 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. |
Band Saw 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. |
NC Control of Cutting and
Auto Cycle |
The NC index control provides greater flexibility and expanded
capabilities compared to a machine with relay logic. The controller
enables the operator to specify the index home position - forward and
clamped or at the index position and open. The controller also
determines the speed of the index vice motion forward and reverse. It
provides independent ramp cycles for the forward and rear traverse. The
speed ramp up and down for moving the work piece is slower when it is
positioning the work piece than when it is moving without work. This
feature provides more accurate indexing of the work piece. |
Band Saw Smart Multiple
Index |
The machine control has the capability to make multiple full length
index strokes until the length remaining to index is less than the full
index stroke (15.8 in., 400mm.) the last index stroke is the remaining
length. |
Band Deviation Monitor ® |
This patented cutting control device can reduce scrap by warning when
the blade is no longer cutting within the operator's settings for
deviation. The allowable deviation limit is set by the operator
independently for each direction. The digital deviation indicator will
flash when the blade deviation exceeds either maximum. If the deviation
continues to exceed the preset value the NC controller will stop the
cutting, raise the saw head and display the exceeded deviation value. |
Band Saw Split Front Vise |
The work holding vise is split so that it clamps the work piece on both
sides of the cutting plane. This additional support in front of the
cutting plane minimizes the burr on the cut pieces. |
Powered Chip Conveyor |
The 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. |
