Thicker the workpiece, the faster the band
speed required and heavier the feed force.
For example, band speed should be at least
6000 fpm (1828.8 m/min.) for 1/4 inch (6.4 mm)
thick carbon steel; 12,500 fpm (3810.0 m/min.)
for one (1) inch (25.4 mm) thick material.
MACHINE CONTROLS
Depending on options supplied (if any), some
controls may not apply to your machine
application.
1.
Band Speed Display.
This digital readout displays
the band speed in feet per mimute.
2.
Band Speed Control.
This control allows the
operator to change the band speed. Turning the
knob
clockwise
to “increase” the band speed;
counterclockwise
to “decrease” it.

FRICTION SAWING
1. The design of this machine makes it ideal for
friction sawing. In friction sawing, momentary
contact between the material being cut and the
fast moving saw band produces enough friction to
heat the material to its softening point. As soon
as it becomes soft, it is cut away by the saw band
teeth. This method cuts many times faster than
conventional methods and cuts many materials that
can not be machined any other way.
2. Keep these important points in mind while friction
sawing:
Roller saw guides are required for friction
sawing.
Attach the spark shield to the post is necessary
for friction sawing. Coolant is not used.
