Symptom
Chips sticking on teeth
Symptom
Premature blade wear
Possible Cause
Insufficient lubricating, refrigerant, or
wrong emulsion
Teeth positioned in the direction opposite
the cutting direction
Possible Cause
Faulty breaking-in of blade
Teeth positioned in the direction opposite
the cutting direction
Poor quality blade
Too fast advance
Wrong cutting speed
Defects on the material or material too
hard
Insufficient lubricating refrigerant or
wrong emulsion
Correction *
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.
Turn teeth to correct direction.
Correction *
See "Material classification and blade selection" and
"Blade break-in procedure"
Turn teeth in correct direction.
Use a superior quality blade.
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.
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 perform cutting
with extreme care, cleaning and remove such
impurities as quickly as possible.
Check level of liquid in the tank. Increase the flow of
lubricating coolant, checking that the coolant nozzle
and pipe are not blocked. Check the emulsion
percentage.
