Corrective Action
Ensure proper coolant flow; hoses unclogged; nozzles pointed
correctly, etc. Make sure coolant type is suitable for the saw.
Check the blade speed and the type of blade you are using.
Also be aware of feed pressure.
With a new blade it is necessary to start cutting at half feeding
speed. After the wearing-in period (a cutting surface of about
2
300 cm
for hard materials and about 1000 cm
materials) the blade and feed speeds can be raised to normal
values.
The swarf wedges into the bottom of the teeth causing
excessive pressure on the teeth themselves. Use a blade with
coarser tooth pitch.
The surface of the cut may have undergone work hardening.
When starting work again, use a lower blade speed and
reduced feed pressure. A tooth from the old blade may be left
in the cut: check and remove before starting work again.
Any movement of the work piece during cutting can cause
broken teeth: check the vise, jaws and clamping pressure.
The blade runs over the material without removing it: increase
feed speed.
The teeth slide over the material without cutting it: reduce the
blade speed.
Check the coolant level and clean coolant lines and nozzles.
Check and use the correct concentration.
The materials may present altered zones either on the
surface, such as oxides or sand, or in section, such as under-
cooled inclusions. These zones, which are much harder than
the blade, cause the teeth to break. Discard or clean these
materials.
Reduce blade speed.
Always check the position of the blade before starting a new
job.
Check the coolant level and clean coolant lines and nozzles.
Reduce feed speed.
Adjust blade tracking according to instructions. If this proves
unsuccessful, contact Palmgren technical support.
Check connections at machine and power source.
Replace fuse/bulb.
