TROUBLESHOOTING GUIDE
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 to better
match the material being cut.
Wrong tooth pitch
Replace blade choosing the proper tooth pitch to
better match the material being cut.
Chips sticking to the teeth and in the
gullets or material that gums
Check to ensure the coolant is being dispersed
properly.
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. Make
sure the parts are securely held.
The blade gets stuck in the material
Decrease the cutting advance and exert less
cutting pressure.
Starting cut on sharp or irregular
section bar
Decrease the cutting advance to allow the blade
to begin its initial 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 to better match the material being cut.
Insufficient coolant. Coolant not flowing or
wrong coolant
Check level of coolant in the tank. Check to
ensure the coolant is flowing freely. Check the
lubricant viscosity. In cold situations the coolant
may need to be heated with the optional heater.
Check and user proper lubricant.
Teeth positioned in the direction opposite
the cutting direction
Remove the blade and reinstall it with the teeth
cutting in the proper direction.
