FAULT
Faulty cut
Streaked cutting surface
Noise on guide blocks
PROBABLE CAUSE
Broken teeth.
Insufficient lubricating refrigerant or
wrong emulsion.
Worn out flywheels
Flywheel housing full of chips
Too fast advance
Poor quality blade
Worn out blade or with chiiped and/or
broken teeth
Wrong tooth pitch
Blade guide block too far from material to
be cut
Insufficient lubricating coolant or wrong
emulsion
Chipped bearings
Worn out or damaged pads
REMEDY
Irregular work of the blade due to the lack of
teeth can cause deflection in the cut
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.
The support and guide flange of the band are so
worn out that they cannot ensure the alignment
of the blade, causing faulty cutting
rolling and drawing tracks can have become
tapered Replace them Clean with
compressed air.
Decrease advance, exerting less cutting
pressure. Adjust the breaking device.
Use a superior quality blade.
Replace it.
Blade used probably has too large teeth
one with more teeth see
classification and blade selection
Types section).
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.
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.
Dirt and /or chips between blade and guide
bearings. Replace theme. Replace them.
