2.1. GENERAL BAR FEEDER DESCRIPTION
The BOSS automatic bar feeder is used in the machi-
ne-tool industry and in particular, for automatic lathe
feeding. It is particularly suitable for feeding fixed or sli-
ding headstock lathes, numerical control or cam la-
thes.
The working cycle is controlled by a control panel with
built-in PLC, which is able to dialogue with the lathe
control.
The main control digital push-button panel makes pro-
gramming easier. An additional push-button panel can
be detached to control the main functions without lea-
ving the lathe.
The bar feeder can be used to feed bars, pipes and va-
rious sections.
The guide channel is fully closed during machining; a
pump is provided to maintain a continuous oil flow insi-
de the channel, creating a hydrodynamic support ef-
fect; these characteristics allow the bar to rotate at a
high r.p.m. number, with no vibrations and no surface
damaging.
The use of a DC motor and of an electronically control-
led clutch make it possible to adjust the feeding speed
and thrust to ideal values at any time during the machi-
ning cycle.
Bar remnant ejection can be caused by bar-pusher fe-
eding or next bar feeding.
