This machine is designed
for unforging, that is carried out in three to five passages, and
equalishing of teeth, that is carried out in one passage.The tests
have shown that cutting productivity is up to three times higher than
in saws with the set teeth.
The quality of cutting is
drastically better as all teeth participate in cutting with unforged
saws.The saw cut is much narrower and consumption of energy is
smaller due to the reduced resistance to cutting.The quantity of
waste material, i.e. scrapings created by cutting is much smaller.
The saw prepared in such
a way can be sharpened five and even more times before the next
IRA 15 was made based on the model
of the German VOLMER PTG device.The gears wheels, shafts and other
vital elements are made of highly qualitative steels that are
cemented, hardened and ground.The head itself is made of steel and it
is absolutely secured against breaking.
