12. Troubleshooting
12.1 Blade and cut diagnosis
Problem
Tooth breakage
Premature blade wear
Blade breakage
Vibrations of the saw
blade
Probable cause
Too fast advance
Wrong cutting speed
Wrong tooth pitch
Poor quality blade
Ineffective gripping of the part in the
vice
Previously broken tooth left in the cut
Cutting resumed on a groove made
previously
Insufficient lubrication, refrigerant, or
wrong emulsion
Material remains on the saw blade
Wrong cutting speed
Wrong tooth shape
Wrong tooth pitch
Poor quality blade
Insufficient lubrication, refrigerant, or
wrong emulsion
Defects on the material or material too
hard
Wrong cutting speed
Wrong tooth pitch
Vibrations
Wrong plaing down of blade
Poor quality blade
Wrong emulsion
Wrong tooth pitch
Wrong tooth shape
Ineffective gripping of the part in the
vice
Dimensions of the tubes are bigger
than allowed
Wrong or too great blade diameter
Remedy
Decrease advance, exerting less cutting
pressure.
Change speed and/or type of blade.
Choose a suitable blade.
Use a superior quality blade.
Check gripping of the part.
Accurately remove all the parts left in.
Make the cut elsewhere, turning the part.
Check level of fluid in tank. Increase the
flow of lubricating refrigerant, checking that
the hole and the liquid outlet pipe are not
blocked. Check the emulsion percentage.
Check the cooling and lubrication emulsion
and use a superior quality blade.
Change speed and/or type of blade.
Choose a suitable blade.
Choose a suitable blade.
Use a superior quality blade.
Check level of fluid in tank. Increase the
flow of lubricating refrigerant, checking that
the hole and the liquid outlet pipe are not
blocked. Check the emulsion percentage.
Reduce the cutting and/or advance speed.
Change speed and/or type of blade.
Choose a suitable blade.
Check gripping of the part.
Use a better and properly sharpened blade.
Use a superior quality blade.
Check the emulsion percentage.
Choose a suitable blade.
Choose a suitable blade.
Check the gripping of the part.
Refer to the instructions.
Reduce the diameter and adapt it to the
size of the workpiece. The cutting piece
may not be bigger than the circumference
of the workpiece.
