2.1 BAR FEEDER GENERAL DESCRIPTION
The SMART 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 operating cycle is controlled by a PLC, integrated in the electrical control panel, which is
able to communicate with the lathe control system. The bar feeder can be used to feed bars,
pipes, various sections and metallic as well as polymeric materials.
Do not use flammable materials.
The guide channel is completely closed during machining; a pump is provided to maintain a
continuous oil flow inside the guide channel, creating a hydrodynamic support effect; these
features allow the bar to rotate at high r.p.m., with no vibrations and no surface damaging.
Thanks to the use of a "BRUSHLESS" and electronically controlled motor, the bar speed, torque
value and feeding position may be determined at any time during the working cycle.
The bar remnant ejection can be performed by the bar pusher feeding or next bar feeding.
The SMART bar feeders are available in the following models:
SMART 320 (standard version)
SMART 320r (reversed version)
The texts, tables and illustrations contained in this manual concern, unless otherwise stated,
the standard version (SMART 320) having the lathe on the operator's right.
• MAIN PARTS
A MOTOR; moves the bar pusher.

B SOLENOID VALVE UNIT; sends signals to the pneumatic components.
C BAR POSITIONING DEVICE; allows finding the bar aligning position on the magazine rack.
D MAGAZINE; stores the bars.
E LUBRICATION PUMP; delivers oil to the guide channels.
F REMNANT RECOVERY BOX; bar remnants are dropped into this box after extraction from the
bar pusher collet.
G KEYBOARD; it allows bar feeder programming and function actuation.
H PRESSURE REGULATOR; to adjust the pressure of the pneumatic devices.
L TELESCOPIC NOSE; allows bar guidance between the bar feeder and the headstock.
M HALF-BUSHING DEVICE, holds the bar centred.
N PNEUMATIC CYLINDER FOR GUIDE CHANNEL OPENING/CLOSING; provides motion to the
pneumatic devices to allow opening/closing the guide channels.
P UPPER GUIDE CHANNELS; drive the bar during the machining.
Q LOWER GUIDE CHANNELS; drive the bar during the machining.
R BAR PUSHER; pushes the bar during the machining.
S FEEDING CHAIN; transmits the motion from the motor to the bar pusher.
T CLAMPS; hold the bar during the loading and removal from the collet of the bar pusher.
U LATHE.

2.2 OPERATING CYCLE
In the automatic operation mode, bar feeder
movements are controlled in the sequence
described below:
The bar pusher (A) feeds bar (B) in the lathe, by
following lathe pulses, until bar end.
The bar pusher (A) and remnant (C) are in their
forwards limit stop position.
The bar pusher (A) and remnant (C) reach their
backwards limit stop position.
The clamps (D) close and the bar pusher moves
back; the remnant is extracted from the collet.
The clamps open and the remnant is dropped into
the box (E).

2 - TECHNICAL INFORMATION SMART320
EN

Clamps (D) close again to perform remnant (C)
extraction check.
If the remnant is still inserted in the bar pusher
collet, the bar feeder stops; otherwise, it
continues its cycle.
Upper guides (H) open together with bar pusher
(A); the bar selection device (F) moves upwards
thus raising the first bar and withholding the
remaining bars. Bar (G) is dropped into the guide
channel.
Bar selection device (F) is lowered.
The first feeding carriage (M) starts its stroke.

2 - Pag. 6 / 20
When the first feeding carriage (M) completes its
stroke, the required space has been created for
bar pusher insertion.
The first feeding carriage performs the return
stroke.
The upper guides (H) are closed; the bar-pusher
(A) is positioned along the spindle axis. The bar
selection device (F) is lowered allowing the bars
to rest on the upper guide holder.
The clamps (D) close, the bar pusher (A) moves
forwards; the bar (G) is inserted into the bar
pusher collet.
The bar pusher (A) and bar (G) perform their
facing stroke. A new automatic working cycle is
started.

2.3 SAFETY DEVICES
A EMERGENCY BUTTON; when pressed, all bar feeder and lathe functions are stopped in an
emergency condition.
C INTERLOCKED SLIDING GUARD: linked to microswitch C1.
according to the cycle setting, its functions are:
manual cycle;
- when the guard is opened, the feeder will be stopped if the guide channels are not
closed.
- when the guard is opened, if the guide channels are closed, the feeder functions are not
disabled because no risks for the operator are present.
- automatic cycle;
- during the bar feeding phase guard opening may be necessary for the purpose of
restocking the magazine. Even if the feeder functions are not disabled, there are no
operator hazards present inside the area.
- during the bar change procedure, the feeder will stop when the guard is opened. The
guard closing allows the user to start the cycle again.

D FIXED GUARD: is made of transparent material to allow visual inspection of the bar magazine
area.
H REMNANT RECOVERY BOX: it also acts as a fixed guard to prevent accidental access to
moving parts.
M MAIN SWITCH: disconnects the electric power supply during the operations in the electrical
control panel and during the bar feeder inactivity periods.
