Manual models feature a band start button on handle and
automatic return of cutting head to rest position the
moment operator interrupts cutting process. Machines are
also fitted with adjustable hydraulic brake, an
indispensable accessory as it makes head descent
independent from operator so improving quality of cut
and increasing band life.
Vices allow rapid nearing and clamping thus ensuring a
strong and secure grip on piece which combined with the
jaw and mobile back rest guarantee that material is
always resting correctly during cutting. The head hinge
pin is fitted on conical roller bearings and is
adjustable to allow compensation of any axial play.
Transmission of motion from motor to band is by means of
reducer in oil bath. Machines are furthermore complete
with dampened limit switch for bow return. Extractable
swarf collection vat, lockable switch, safety micro
switches on band covers, and variable speed drive unit
are standard equipment. Loading, unloading tracking is
also available.
Semi Automatic
Semi-automatic model can make single cuts without
presence of operator. The wide circular base is fitted
on ball track and this makes rotation and positioning
extremely fast and precise also thanks to adjustable
mechanical stops. Machines have bow inclined upon the
vertical by 35°, inclination which together with big
diameters of flywheel limit as far as possible the
yielding of the band; to this we can add the adjustable
blade guide device which noticeably reduces wear on
band. Semi-automatic band saws can be supplied with
two-speed selector or with variable speed drive unit.
All machines are supplied with rapid band tensioning
device, very practical and reliable it immediately gives
a constant tension of 600 kg. Standard equipment is the
band rotation sensor which allows control unit to check
work overload, excessive reduction of number of
revolutions or to stop machine in case of band breakage.
One can adjust position and speed of the pneumatic or
hydraulic head movement unit. Position of bow is read by
a linear potentiometer by means of which one can set
cutting start and end position. The PLC which controls
this series of semi-automatic machines has been
developed especially to obtain the correct sequence of
cutting and to give all the extremely useful diagnostic
messages. The control panel is complete with membrane
key-pad with can be used even in critical environments
with no risk of wear. Digital display with large
characters and icon commands make use of this machine
simple and intuitive.
Fully Automatic
Machines with automatic feeder are designed to cut
single bars or whole bundles unassisted until material
is exhausted: this makes them very flexible machines
which can be used even for particularly exacting work.
This family of machines can be supplied with two axis
numeric control and electronic blade speed rotation.
Adjustment of descent speed, control of cutting head's
position by means of linear potentiometer and the
proximity switches which in every moment monitor the
state of machine guarantee sturdiness, long working life
and flexibility of use. Models available include 45°
left and 60 ° right mitre cutting models, with head
supported upon conical roller bearings which eliminate
any axial play and make cutting unit adaptable even to
most exacting working conditions. Moto-reducer is placed
in vertical position to reduce rear dimensions of
machine, cutting bow is balanced and step feeder has
been designed so as to reduce end scrap to minimum. Here
again the control panel, with large visual display and
icon keys allows one to easily access, in an intuitive
manner all machine functions, with simultaneous
visualisation of the various diagnostic messages. The
presence of a rotation sensor guarantees an extremely
high level of safety which together with the mechanical
structure involved in band's movement, preserve motor
from overloads and makes band's life much longer. The
machines also come with a wide range of accessories such
as automatic expulsion of cutting swarf, vertical
anti-burr vice and loading/ unloading tracking .
