TROUBLESHOOTING

This chapter lists the probable faults and malfunctions that could occur while the machine is being used and suggests possible
remedies for solving them.
The first paragraph provides diagnosis for TOOLS and CUTS, the second for ELECTRICAL COMPONENTS.

12.1 - Blade and cut diagnosis

FAULT

PROBABLE CAUSE

REMEDY

TOOTH BREAKAGE

Too fast advance

Wrong cutting speed

Wrong tooth pitch

Low quality disk
Ineffective gripping of the part in the
vice.
Previously broken tooth left in the cut
Cutting resumed on a groove made
previously.
Insufficient lubricating refrigerant or
wrong emulsion

Sticky accumulation of material on
the disk.

Decrease advance, exerting less cutting
pressure
Change disk speed and/or diameter.
See Chapter

“ Material classification

and choice of disks”

and the Table of

cutting speeds according to disk diameter.
Choose a suitable disk.
See Chapter “Material classification
and choice of disks”.
Use a better quality disk.
Check the gripping of the part.

Accurately remove all the parts left in.
Make the cut elsewhere, turning the part.

Check the level of the liquid in the tank.
Increase the flow of lubricating refrigerant,
checking that the hole and the liquid outlet
pipe are not blocked.
Check the blend of lubricating coolant and
choose a better quality disk.

See Chapter “Material classification
and choice of disks”

in the paragraph

Running in the disk.

Change disk speed and/or diameter.
See Chapter “Material classification
and choice of disks” and the

Table of

cutting speeds according to disk diameter.

Choose a suitable disk. See Chapter
“Material classification and choice of
disks” in the paragraph on

Type of disks.

Choose a suitable disk.
See Chapter “Material classification
and choice of disks”.
Use a better quality disk.
Check the level of the liquid in the tank.
Increase the flow of lubricating refrigerant,
checking that the hole and the liquid outlet
pipe are not blocked.

CHIPPED DISK

Hardness, shape or flaws in the mate-
rial (oxides, inclusions, lack of homo-
geneity, etc..)
Wrong cutting speed

Wrong tooth pitch

Vibrations
Disk incorrectly sharpened

Low quality disk

Reduce the cutting pressure and/or the
advance.

Change disk speed and/or diameter. See
Chapter “Material classification and
choice of disks” and the

Table of cutting

speeds according to disk diameter.
Choose a suitable disk.
See Chapter “Material classification
and choice of disks”.
Check gripping of the part.
Replace the disk with one that is more
suitable and correctly sharpened.
Use a better quality disk.
