Symptom
Blade Breakage
Symptom
Blade Breakage
Possible Cause
Faulty welding of blade
Possible Cause
Too fast advance
Wrong cutting speed
Wrong tooth pitch
Ineffective gripping of the part in the vice
Blade touching material at beginning of
cut
Remedy
Possible Cause
Blade guide pads not regulated or dirty
because of lack of maintenance
Blade guide block too far from material to
be cut
Correction *
The welding of the blade is of utmost importance.
The meeting surfaces must perfectly match and once
they are welded they must have no inclusions or
bubbles; the welded part must be perfectly smooth
and even. They must be evenly thick and have no
bulges that can cause dents or instant breakage when
sliding between the blade guide pads.
Correction *
Decrease advance, exerting less cutting pressure.
Adjust the braking device.
Change speed and/or type of blade.
See chapter on "Material classification and blade
selection", in the section Blade selection table
according to cutting and feed speed.
Choose a suitable blade. See Chapter "Material
classification and blade selection."
Check the gripping of the part.
At the beginning of the cutting process, never lower
the saw bow before starting the blade motor.
Correction *
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.
