3.3. Operation Recommendations
Select the correct saw blade with the correct tooth pitch & form to suit the material to be cut to provide
minimum burr & maximum blade lifespan.
o
SA350 Blade Sizes 320-350 mm
o
SA400 Blade Sizes 350-400 mm
Use the smallest diameter blade & coarsest pitch that is practical within the required speed & material
limitations.
Generally, use a tooth pitch to give 2 - 4 teeth engagement with the material during cutting.
Ensure that sufficient coolant is flowing over the cutting teeth.
Do not allow the machine’s gearbox to run idle in the upright position for more than
3 minutes
otherwise,
damage can occur to the drive system.
The rate of feed affects the quality of the final cut & blade life. This varies also by the material & cross-
sectional dimensions. When cutting stainless steel or high carbon steel (
Brinell hardness above 200
), the
slowest speed machine should be used together with a cobalt type high-speed steel blade.
As a rule of thumb
the softer the component, the faster the rate of speed
. Thus, it is recommended that
slower speeds be used for hard & tough materials & higher speeds for soft, ductile materials. Note that for
non-ferrous materials such as brass, copper, aluminium etc. require much faster speeds than provided on
this machine. If these are the majority of materials cut, a
Brobo
NF Series
machine should be considered.
