SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Tooth breakage
Cut advancing too quickly
Decrease cutting advance, exerting less cutting
pressure. Adjust the braking device.
Wrong cutting speed
Change speed and/or type of blade.
See OPERATION - BLADE SELECTION
GUIDE LINES page 9.
Wrong tooth pitch
Replace blade choosing the proper tooth pitch.
See OPERATION - BLADE SELECTION
GUIDE LINES page 9.
Chips sticking to the teeth and in the
gullets or material that gums
Check to ensure the coolant outlet hole on the left
blade guide is not clogged and the coolant flow is
adequate to remove of chips from the blade.
Defects on the material or material too
hard
Material surfaces can be oxidized or covered with
impurities making these areas harder than the
blade itself. Materials may have hardened areas
or inclusions inside the section due to production
materials such as castings and welding wastes,
etc. Avoid cutting these materials. In a situation
where a cut has to be made use extreme care,
cleaning and removing hard impurities as quickly
as possible.
Ineffective gripping of the part in the vise.
Check the gripping of the part being cut. Tighten
the vise as needed.
The blade gets stuck in the material
Decrease the cutting advance and exert less
cutting pressure.
Starting cut on sharp or irregular
section bar
Pay more attention when you start cutting. Slowly
and carefully start the cut.
Poor quality blade
Switch to a superior quality blade.
Previously broken tooth left in the cut
Remove in the broken tooth from the cut.
Resuming a cut on a previously made
groove
Make the cut elsewhere, turning the part over.
Vibrations
Check the grip of the part being cut to ensure it is
being held securely in the vise.
Wrong tooth pitch or shape
Replace blade choosing the proper tooth pitch or
shape. See OPERATION - BLADE SELECTION
GUIDE LINES page 9. Adjust blade guides.
Insufficient lubricating, refrigerant, or
wrong lubricant viscosity
Check level of liquid in the tank. Increase the
flow of lubricant. Check to ensure the hole and
the liquid outlet pipe are not blocked. Check the
lubricant viscosity.
Teeth positioned in the direction opposite
the cutting direction
Remove the blade and reinstall it with the teeth
cutting in the proper direction.
