2.1 GENERAL DESCRIPTION OF THE BAR FEEDER
The MASTER 880 automatic bar feeder is used in the machine-tool industry and in particular,
for automatic lathe feeding.
The working cycle is controlled by a control panel with built-in PLC, which is able to dialogue
with the lathe control.
The digital hand-held keyboard makes programming easier and allows the bar-feeder functions
to be controlled without leaving the lathe.
The bar feeder can be used to feed bars, pipes and various sections.
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 motor, the bar speed, thrust
value and feeding position may be determined at any time during the working cycle.
Bar remnant ejection can be caused by bar-pusher feeding or next bar feeding.
The lathe tooling and maintenance can be easily carried out due to the axial displacement of
the bar feeder body.

2.1.1 Bar feeder - Main components
A Magazine; where bars are stored.
B Bar selectors; this selects the first bar contained in the magazine, so that it can be
afterwards loaded by the lifting device.
C Bar lifting device; this lifts the first bar contained in the magazine.
D Guide channels; they drive the bar during the machining.
E First feeding carriage; it pushes the bar forward until the necessary space for the bar pusher
connection has been created.
F Bar pusher; it pushes the bar during the machining. The collet is fixed on its front end.
G Bar pusher drive; it drives the bar pusher.
H Feed chain; it transmits the motion from the drive to the bar pusher.
L Guide channel opening/closing cylinder
Y Upper guide channel unlock
M Pneumatic bar drop control devices; they control the bar during the drop into the guide
channels.
N Clamps; they hold the bar during its loading and removal from the bar pusher collet.
P Facing device; it sends a signal during the bar passage.
Q Remnant collection box; it collects the bar remnant.
R Lubricating pump; it delivers oil to the guides.
S Oil tank; contains the lubricating oil.
T Hand-held keyboard; it allows bar feeder programming and function actuation.
U Electric cabinet; houses the electric switchboard.
V Axial displacement; it helps to remove the bar feeder body from the lathe.
Z Pneumatic bar drop controls cylinder
X Pneumatic clamps cylinder

Lubrication oil cycle: forced by pump (2) installed in tank (1), the oil flows to guides (4) and
bushing holder (5) to lubricate the bars in production.
From these two devices the oil enters recovery tray (6) from where it is returned to the tank
via a filter for use in the next lubrication cycle.

2.2 OPERATING CYCLE
The automatic functioning controls the motions of the bar feeder according to the sequence
described below.
The bar pusher (A) makes bar (B) move forward in the lathe until the bar runout.
The bar-pusher (A) and remnant (C) are in their forwards limit stop position.

When dropping, bar remnant (C) activates a control device. If the bar remnant is still inside the
collet of the bar pusher, the bar feeder stops, otherwise the cycle goes on.
The top guides (G) are lifted together with the bar pusher (H), and also the bar control devices
are lifted.

Bar lifts (L) load bar (M) that falls into lower guides (N) with the help of levers (H).
The 1st feeding carriage (P) stroke begins.
When the small pusher truck (P) completes its stroke, the required space has been created for
bar-pusher insertion.
The small pusher truck executes its return stroke.

The upper guides (G) are closed; the bar-pusher (H) is positioned along the spindle axis.
The clamps (D) close, the bar-pusher (A) moves forwards; the bar (N) is inserted into the bar-
pusher collet.
The bar-pusher (A) and bar (N) execute their facing stroke. A new automatic work cycle is
started.

2.3 Bar feeder - Safety devices
A-B Emergency push-button; when pressed, all the bar feeder and lathe functions stop in
emergency condition.
C Interlocked mobile guard: associated with microswitch C1.
According to the cycle setting, its functions are.
manual cycle;
-on guard opening, the bar feeder controls are locked with the exception of bar pusher
movement controls.
automatic cycle;
-during the bar feeding phase, the guard opens to allow magazine refilling. Although the bar
feeder and lathe functions are not stopped, there are no residual risks for the operator
within the area.
-during the bar change phase, on guard opening, the bar feeder and lathe functions are
stopped. Guard closure allows the cycle to be restarted by the operator.
D Fixed guard: it is made from transparent material to allow visual inspection of the bar feeder
devices.
E Fixed guard: hinders an accidental access to the operating components.
F Fixed guard: it prevents accidental access to the bar selection area.
