to Break In a Blade
- Use the appropriate band speed for
the material to be cut (see bi-metal band speed chart).
- Reduce the feed rate/force control
on the saw to achieve a cutting rate approximately 20%
to 50% of the normal cutting rate.
Mild steels require a larger reduction in cutting
rate than more difficult to machine materials.
- Begin the first cut at the reduced
rate (A), making sure that the teeth are forming a chip. Once the blade fully
enters the workpiece, the feed rate can be slightly
- Make gradual increases in feed rate/force
over several cuts until the normal cutting rate is established
(cutting a total of 60 to 118 inches2
/ 150 to 300 cm2) (C).
Note: During break-in,
slight adjustments to band speed may be made in the event
of excessive noise or vibration.
Once the blade is broken in, the recommended band speed
should be used.
