SETTING FEED RATE
Feed rate is the speed at which the band
saw blade cuts through the work-piece.
The feed rate is set by adjusting the feed
rate dial. The feed ON/OFF lever starts
and stops lowering the bow.
TO SET THE FEED RATE:
Raise the bow to the highest position and
lock it in place using the feed ON/OFF
lever.
Set the feed rate dial to the desired feed
rate.

Turn On the pump and the band saw and
start cutting.
If the chips are evenly shaped, slightly
curled with a slight colour change, the
feed rate, blade speed, cutting fluid type,
and blade type are correct.
If the chips are tightly curled, warm,
brown to black in colour, reduce the feed
rate and increase the blade speed or
both.
If the metal chips are blue coloured,
reduce the blade speed, use cutting fluid,
reduce the feed rate or reduce all three.
If you get thin powder life silver coloured
chips, increase feed rate, decrease the
blade speed or both.
CUTTING FLUID
Before using the cutting fluid, consider the
type, hardness and shape of the material
being cut. Choosing the right cutting fluid
also depends on blade feed rate, blade
TPI, tooth type and cutting speed. Make
sure to read and follow all the product
instructions on the product.
Below are some tips for choosing the right
cutting fluids:
For cutting low alloy, low carbon and
general purpose metals with a bi-metal
blade, always use water soluble cutting
fluids.
For cutting stainless steel, high alloy, high
carbon metals, brass, copper and mild
steels, use neat cutting oil that have
extreme pressure additives.
For cutting cast iron, you do not need to
use any cutting fluids.
