11.3 Operation Procedure
Operation of this band saw is quite simple once the function
of each control and feature is understood.
!
Material longer than the table must be properly
supported to prevent unintended movement.
!
Never operate band saw without blade and wheel
covers in place and secured.
1.
Turn the main disconnect switch to On and allow the
system to boot up.
2.
Twist and release the Emergency Stop Switch.
3.
Turn the LAMP ON/OFF switch to the ON position.
4.
Raise the guide arm high enough to clear the material. If
tilting the bow to the left. This will also need to clear the
vise.
5.
Determine the angle of the cut. Use the lock lever to
loosen the saw bow and manually tilt the bow from 45° left
tilt to 45° right tilt. Never rely solely on the scale markers
for the correct tilt angle. Always verify the angle with a
protractor.
6.
Mark the material for the location and angle of the cut.
7.
Place the material between the vise plates. The vise
may be positioned on either side of the cut and has other
forward and aft adjustments.
8.
Align the cut mark with the saw blade.
9.
Close the vise to clamp the material.
10. Turn the coolant switch to On to start the coolant flow.
Adjust the flow at the nozzle using the ball valve located
at the nozzle.
11. Press the START switch to start the saw blade and
advance the saw bow into the cut.
NOTE: Reference Table 4 - Speed and Pitch chart in Section
14.0. Select the speed setting for the material to be cut.
12. Adjust the saw blade speed using the adjustment knob
on the right side of the console and monitoring the speed
using the blade speed indicator. Set the speed so that the
speed is ±5 SFPM of the desired setting. Getting an exact
match will be difficult.

13. Set the feed pressure to a pressure as recommended in
pressure chart, Table 2 - Recommended Feed Force.
14. Press the "STOP" button to stop the bow movement if
necessary. The saw bow will advance until the forward
stop limit switch is engaged. The saw blade will then stop,
the frame will retract to the home position and wait for the
next cut cycle.
15. Slowly turn the feed speed knob counterclockwise (CCW)
until the feed speed is set. This value is the "Cutting Rate"
from the Cutting Chart. It is listed in Surface Inches Per
Minute (SIPM).
16. Once the feed rate and pressure cutting rate are set,
lightly tighten the lock knobs to hold these setting. This
will keep the settings for as long as the same material is
to be cut.
17. When the cut is complete, (either by the feed stroke limits
or by the operator pressing the STOP button) the saw
blade will stop and the saw bow will retract to the start
position.
18. Once the saw frame has returned to the home position, the
saw may be set for the next cut. This will be determined by
each specific project to be sawed.
NOTE: It is recommended to check the first cut for accuracy.
Make any adjustments before cutting the remaining stock.
If the saw frame is not set at 0° the saw will not cut squarely.
19. When the saw is not in operation, power the saw down by
pressing the E-Stop. If leaving the saw unattended, turn
the main disconnect to the Off position.
11.4 Evaluating Cutting Efficiency
The best way to determine whether a blade is cutting
efficiently is to observe the chips formed by the cutting.
•
If chip formation is powdery, then the feed rate is too
light, or the blade is dull.
•
If the chips formed are curled, but colored – blue or
straw colored from heat generated during the cut –
then feed rate is excessive.
•
If chips are slightly curled and not colored by heat, then
the blade is sufficiently sharp and is cutting at its most
efficient rate.
