From
the mechanical point of view the
machine has all those shrewdnesses,
derived by a forty-year-old experience
in the sector, that guarantee sturdiness,
precision and reliability in the
time.
Head: The head,
with hole Ø 111 mm, is melted
in special Meehanite stabilized
cast-iron, steadily fixed on the
bed and it is free from vibrations.
All the gears, in steel Cr.Ni.Mo,
hardened and ground, are mounted
on high precision bearings. The
spindle is supported in three points
and is mounted on precision TIMKEN
ball bearings. The speed gear range
(2 ranges with continuos change)
is mechanical so as to enable high
working torques and it can be manual
or automatic by means of an hydraulic
piston and relative unit.
Toolholder turret
: The machine can be equipped, according
to the customer requests, with manual
turrets with rapid change, electromechanical
ones with four positions or eight
positions.
Bed: the bed is
of the type covered on the whole
length and of sturdy structure with
stiffening ribs that assure an absolute
undeformability. It is melted in
special Meehanite cast-iron and
the slide guides largely sized,
induction hardened and carefully
ground maintain an absolute precision
to the surface. Very useful is the
natural gap under head allowing
to work flanges, usually workable
on very big machines.
