» maximum cutting speed of each individual band saw blade is
specified by the band saw manufacturer
» the harder is the material which you cut, the lower cutting speed
shall be used
» when cutting soft wood types, it is recommended to use larger
tooth pitch; when cutting hard wood types, it is recommended to
use smaller tooth pitch
» before you start cutting, check that the band saw blade is properly
sharpened, set and whether it is not damaged or heated up (such
heating-up is characterised by purple colour which remains even
when it has cooled down)
» before you use a new band saw blade for the first time, it is necessary
to let it “run in” (operate it for 20 minutes with no work load)
– then it must “rest” for 24 hours
» if a heat-up of band saw blade occurs during cutting operation, it is
necessary to put it out of operation, leave it to cool down and then
re-sharpen it and check its flatness
» heat-up is best prevented by timely sharpening of blades and by
compliance with specified cutting conditions
» it is necessary to regularly replace the band saw blades even if the
toothing is not dull – thus they keep their mechanical characteristics
for a prolonged period of time
» band saw blades must be adequately and evenly tensioned in the
machine (however, not excessively, otherwise they may break –
comply with the machine manufacturer’s specifications)
