FAULT PROBABLE CAUSE REMEDY
Blade guide pads not regulated or dirty
because of lack of maintenance
Blade guide block too far from material
to be cut
Improper position of blade on flywheels
Insufficient lubricating coolant or wrong
emulsion
Check distance between pads (see
"Machine adjustments" in the Blade
Guide Blocks section): extremely
accurate guiding may cause cracks
and breakage of the tooth. Use
extreme care when cleaning.
Approach head as near as possible to
material to be cut so that only the blade
section employed in the cut is free, this
will prevent deflections that would
excessively stress the blade.
The back of blade rubs against the
support due to deformed or poorly
welded bands (tapered), causing
cracks and swelling of the back
contour.
Check level of liquid in the tank.
Increase the flow of lubricating
refrigerant, checking that the hole and
the liquid outlet pipe are not blocked.
Check the emulsion percentage.
STEAKED OR ETCHED
BANDS
Damaged or chipped blade guide pads
Tight or slackened blade guide
bearings.
Replace them.
Adjust them (see Chapter "Machine
adjustments" in Blade guide section).
CUTS OFF THE STRAIGHT Blade not parallel as to the counter
service
Check fastenings of the blade guide
blocks as to the counter-vice so that
they are not too loose and adjust
blocks vertically; bring into line the
position of the degrees and if
necessary adjust the stop screws of the
degree cuts.
Check and vertically re-adjust the blade
guide blocks; reset proper side guide
play (see Chapter "Machine
adjustments" In Blade guide section).
Decrease advance, exerting less
cutting pressure. Adjust the braking
device.
Approach it as near as possible to
material to be cut so that only the blade
section employed in the cut is free, this
will prevent deflections that would
excessively stress the blade.
Replace it. Blade with major density of
teeth is being used, try using one with
less teeth (see Chapter "Material
classification and blade selection" in
the Blade Types section).
Blade not perpendicular due to the
excessive play between the guide pads
and maladjustment of the blocks
Too fast advance
Worn out blade
Wrong tooth pitch
