SOLUTION
PROBABLE CAUSE
PROBLEM
Rapid tooth wear
'
Teeth pointing in the wrong
direction
.
Set teeth in correct direction
'
Blade worn in wrongly
.
With a new blade cutting
should be done at
half--speed and with
downstroke speed also at
half normal speed. After the
blade has been worn in
(about 300 cm
2
of work for
hard cutting materials and
about 1000 cm
2
for soft
cutting materials) the cutting
and downstroke speeds can
be brought up to rated levels
'
Material too hard
.
Check cutting speed,
downstroke speed and blade
pressure, as well as type of
band saw being used
'
Material defective
.
Surface defects: oxides,
sand, surface hardening.
Hardened inclusions in
section.
Reduce cutting and
downstroke speeds or clean
surface.
'
Cutting speed too high
.
The teeth slide on the
material without cutting:
reduce cutting speed
'
Head downstroke speed too
slow
.
The band saw runs over the
material without removing it:
increase downstroke speed
'
Insufficient coolant
.
Check coolant level and
clean pipes and jets
'
Incorrect fluid concentration
.
Check and use the correct
concentration
'
New blade inserted into a
partially--made cut
.
The cutting surface might
have been subject to a
localised heat--induced
alteration, making it harder:
recommence cut using a
slower cutting and
downstroke speed. There
may be a broken tooth from
the old blade lodged in the
cut: check and remove
before recommencing work
'
Flutter
.
Blade tension too low:
tighten.
Tooth shape or pitch
unacceptable: change type
of blade used.
Widia blade steady buttons
too far from the blade back:
adjust guide heads, rotating
them slightly to bring them
closer to the blade back.
