SOLUTION
PROBABLE CAUSE
PROBLEM
Teeth breaking
'
Disc not worn--in correctly
.
With a new disc it is neces-
sary to start cutting at half
feeding speed. After the
wearing--in period (a cutting
surface of about 300 cm2 for
hard materials and about
1000 cm
2
for soft materials)
the cutting and feed speeds
can be brought up to normal
values.
'
Disc with excessively fine
tooth pitch
.
The swarf wedges into the
bottom of the teeth causing
excessive pressure on the
teeth themselves.
'
New blade inserted in a par-
tially completed cut.
.
The surface of the cut may
have undergone local ther-
mal alteration, making it
harder: when starting work
again, use a lower cutting
speed and head feed speed.
A tooth from the old blade
may be left in the cut: check
and remove before starting
work again.
'
Workpiece not clamped firmly
in place
.
Any movement of the work-
piece during cutting can
cause broken teeth: check
the vice, jaws and clamping
pressure.
'
Vibration
.
Workpiece vibrates in the
vice: check that the slide has
been adjusted correctly;
check the clamping pressure
and if necessary increase.
Rapid tooth wear
'
Head speed too slow
.
The blade runs over the ma-
terial without removing it: in-
crease head speed.
'
Cutting pressure too high
.
Reduce cutting pressure.
'
Cutting speed too high
.
The teeth slide over the ma-
terial without cutting it: re-
duce the cutting speed.
'
Insufficient coolant
.
Check the coolant level and
clean piping and nozzles.
'
Incorrect fluid concentration
.
Check and use the correct
concentration.
