Symptom
Blade Breakage
Symptom
Steaked or etched bands
Symptom
Cuts off the straight
Possible Cause
Improper position of blade on flywheels
Insufficient lubricating coolant or wrong
emulsion
Possible Cause
Damaged or chipped blade guide pads
Tighten or slackened blade guide bearings.
Possible Cause
Blade not parallel as to the counter service
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
Broken teeth
Insufficient lubricating refrigerant or
wrong emulsion
Correction *
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.
Correction *
Replace them.
Adjust them (see Chapter "Machine adjustments" in
Blade guide section).
Correction *
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 used,
try using one with less teeth (see Chapter "Material
classification and blade selection" in the Blade Types
section).
Irregular work of the blade due to the lack of teeth
can cause deflection in the cut; check blade and if
necessary replace it.
Check level of liquid in the tank. Increase the flow of
lubricating coolant, checking that the hole and the
liquid outlet pipe are not blocked. Check the
emulsion percentage.
