2.1 BAR FEEDER GENERAL DESCRIPTION
The bar feeder in question has been planned and manufactured in order to automatically feed
the bars to be turned on the lathe.
It can feed bars with different (round, square, hex) sections and of maximum length equal to
that of the spindle liner.
The operating cycle is directed by a PLC, integrated in the electrical control panel, which
interacts with the lathe controls.
The bar feeder is provided with a remote control allowing the operator to perform operations in
manual mode (tooling phase) without leaving the working area.
The phase of preparation and tooling of the working change (diameters or different sections) is
extremely easy and quick.
Remnant ejection can take place with the feed either of the bar pusher or of the following bar.

2.1.1 MAIN COMPONENTS
A Magazine; it contains bars to be loaded.
B Bar selecting device; it takes the first bar out of the magazine and lays on the "bar drop
control device".
C Bar limit stop device; it regulated correctly the position of the first bar inside the magazine,
before it is lifted by the bar selecting device.
D Bar drop control unit; this device lays the bar onto the guide channel.
E Guide channel; this device drives the bar and introduces it correctly into the lathe.
F Truck; this device introduces the bar into the lathe.
G Bar pusher; this device pushes the bar inside the lathe until it has been completely
machined.
L Bar feeding motor; thanks to a toothed belt, motions are transmitted to the truck and to the
bar pusher.
M Cam drive unit; it starts the cams of bar selecting and bar drop control devices as well as
the bar limit stop cams.
N Side keyboard; thanks to this keyboard it is possible to set up programming and to start bar
feeder working phases.
P Electric cabinet; it contains the electric control panel.
Q Remote control; this device allows the operator to control operations remotely in manual
mode.

2.2 WORKING CYCLE
The possibile working cycles are listed hereunder:
- REGULAR CYCLE; the bar is fed until it reaches the lathe bar stop.
- FIXED PIECE FEED OUT; the bar feeling is exact and accurate (no lathe bar stop is needed).
In the following paragraphs you will find a concise description of the phases it this working
cycle.
INFORMATION:
for further detailed information about working cycle selection and setting,
please see the side keyboard instruction manual, in particular parameter 29.
2.2.1 REGULAR CYCLE
- At the stop of the lathe
operating cycle, the bar pusher
(A) moves back to the limit stop
position.
- The bar pusher (A) and the "bar
drop control" unit (B) are lifted.
At the same time, also the bar
selecting unit (C) that loads the
first bar on the "bar drop
control" unit is lifted.

2 - TECHNICAL INFORMATION KID 70
GB
2 - Pag. 5 / 16
- The "bar drop control" unit (B)
returns to its initial position
enabling bar insertion into the
guide (D). At the same time, the
bar selector unit (C) returns to
its initial position. Subsequently,
the guide lifts and sets the bar
in line with the loading axis.
- The bar is inserted into the
carriage lathe (E) that then goes
back to its initial position.
- The guide (D) returns to its low
position. The bar pusher (A)
lines up with the loading axis of
the lathe spindle.

2 - TECHNICAL INFORMATION KID 70
2 - Pag. 6 / 16
- The bar pusher (A) inserts the
bar into the spindle liner. The
bar ejects the remnant (F) as a
residual of the previous
machining, and is positioned for
the facing.
The lathe operating cycle starts at
the beginning of the bar facing
phase.
At this point the bar is fed till it
reaches the lathe bar limit stop,
then machining phase takes place
until one piece has been fully machined.
The latter phase os repeated several times till the bar has been completely machined.
INFORMATION: In order to save time, it is possible to start the bar change phase when the
lathe is machining th last workpiece.
2.2.2 "FIXED PIECE FEED OUT" CYCLE
- At the stop of the lathe
operating cycle, the bar pusher
(A) moves back to the limit stop
position.

2 - TECHNICAL INFORMATION KID 70
GB
2 - Pag. 7 / 16
- The bar pusher (A) and the "bar
drop control" unit (B) are lifted.
At the same time, also the bar
selecting unit (C) that loads the
first bar on the "bar drop
control" unit is lifted.
- The "bar drop control" unit (B)
returns to its initial position
enabling bar insertion into the
guide (D). At the same time, the
bar selector unit (C) returns to
its initial position. Subsequently,
the guide lifts and sets the bar
in line with the loading axis.
- The bar is inserted into the
carriage lathe (E) that then goes
back to its initial position.

- The guide (D) returns to its low
position. The bar pusher (A)
lines up with the loading axis of
the lathe spindle.
- The bar pusher (A) inserts the
bar into the spindle liner. The
bar ejects the remnant (F) as a
residual of the previous
machining, and is positioned for
the facing.
The lathe operating cycle starts at
the beginning of the bar facing
phase.
At this point the bar is precisely fed
according to the value which has
been set, then machining phase
takes place until one oiece has been fullt machined.
The latter phase is repeated several times till the bar has been completely machined.
INFORMATION: In order to save time, it is possible to start the bar change phase when the
lathe is machining th last workpiece.

2.3 SAFETY DEVICES
The figure indicates the position of the devices on the bar feeder.
A- Interlocked sliding guard: is associated with an interlock device (microswitch A1). At the
opening of the guard, in emergency condition, all the bar feeder and lathe functions stop. At
the closing of the guard it is possible to start the operating cycle again.
This one is endowed with a porthole allowing the visual inspection of the bar handling main
components.
B- Emergency push button: if started, each component of the bar feeder and of the lathe
immediately stops. After having normalised the operating conditions it is required to release
the button, with a voluntary action, in order to authorise again the bar feeder and lathe
setting into operation.
C- Drive fixed guard: prevents the access to the components in motion.
