2.1 GENERAL DESCRIPTION OF THE BAR FEEDER
The MASTER 880 E-volution automatic bar feeder is
used in the machine-tool industry and in particular,
for automatic lathe feeding. It is particularly
suitable for feeding fixed or sliding headstock
lathes, numerical control or cam lathes.
The working cycle is controlled by a control panel
with built-in PLC, which is able to dialogue with the
lathe control.
It is equipped with a hand-held control that enables
the operator to interact with all the controls
without forcing him to leave his work station.
It may load bars, tubes and various sections that
are kept in the rack magazine (MASTER 880P) or in
the bar bundle magazine (MASTER 880F).
The guide channel is fully closed during machining;
a pump is provided to maintain a continuous oil
flow inside the channel, creating a hydrodynamic
support effect; these characteristics allow the bar
to rotate at a high r.p.m. number, with no
vibrations and no surface damaging.
Thanks to the use of a "BRUSHLESS" and
electronically controlled motoreductor, the bar
speed, thrust value and feeding position may be
determined at any time during the working cycle.
