Choosing The Saw Blade - Promac SX-815DV Mode D'emploi

Rounding of teeth
A carefully broken in blade lasts much longer and gives
better performance.
To break in your new blade, run it at only 30% of normal
pressure for ten minutes.
Then gradually increase to normal pressure.
Feed pressure selection:
A good indication of proper feed pressure is the shape of the
cutting chips.
Perfect:
Loose curled chips
If the chips are thin or powdered increase the feed pressure.
If the chips are burned reduce the cutting speed and
decrease the feed pressure.
8. Choosing the saw band
1) Choose a toothing that is appropriate to the workpiece
being processed. Ideally, at least 3 teeth should be in action
at the same time.
2) The toothing should not be smaller than necessary, as the
cutting speed is reduced if there are too many small teeth
working on the workpiece simultaneously, which causes the
saw band to wear more quickly, and makes the cuts crooked
and distorts them.
3) The following table shows the approximate toothing of the
saw bands for a specific material thickness. For further
information please contact your saw band dealer.

Comments
1) 10/14 toothing provides good cutting results for thin-
walled pipes and profiles.
2) The choice of toothing (i.e. the number of teeth per inch)
should be such that at least 3 teeth are always in action at
the same time.
When cutting thick material, a coarse Tooth Pitch "T" is
needed to accommodate the big chips (Fig 7)
