12.1 Blade and Cut Diagnosis

Symptom
Tooth breakage
Possible Cause
Too fast advance

Chips sticking onto teeth and in the gullets
or material that gums
Defects on the material or material too
hard
Ineffective gripping of the part in the vise
The blade gets stuck in the material
Starting cut on sharp or irregular section
bars
Poor quality blade
Previously broken tooth left in the cut
Cutting resumed on a groove made
previously
Vibrations

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 for clogging of coolant drain holes on the
blade-guide blocks and that flow is plentiful in order
to facilitate the removal of chips from the blade.
Material surfaces can be oxidized or covered with
impurities making them, at the beginning of the cut,
harder that the blade itself, or have hardened areas
or inclusions inside the section due to productive
agents used such as casting sand, welding wastes,
etc. Avoid cutting these materials or in a situation a
cut has to be made use extreme care, cleaning and
remove any such impurities as quickly as possible.
Check the gripping of the part.
Reduce feed and exert less cutting pressure.
Pay more attention when you start cutting.
Use a superior quality blade.
Accurately remove all the parts left in.
Make the cut elsewhere, turning the part.
Check gripping of the part.
Replace blade with a more suitable one.
See "Material classification and blade selection" in
the Blade Types section.
Adjust blade guide pads.
