2.2 GENERAL BAR FEEDER DESCRIPTION
The automatic bar feeder SIR52 MS32 P o SIR52 MS32 F, hereinafter referred to as the bar
feeder, works in the field of the machine tools, more specifically to feed a multi-spindle lathe
automatically.
The bar feeder has been designed to be installed instead of the lathe stock tube, thus replacing
the bar guiding and feeding systems. It allows round, hexagonal and square bars to be loaded.
The working cycle is controlled by a PLC fitted in the electric switchboard, able to dialogue with
the lathe control.
A LATHE
machines the bars loaded by the bar feeder.
B RACK MAGAZINE
stores the bars.
C CONVEYING DEVICE
takes single bars, moving them from the rack magazine to the inserting device.
D DRIVE
drives the bar traverse device from the rack to the inserting device.
E BUNDLE MAGAZINE
stores bars.
F BAR SELECTING DEVICE
selects bars.
G DRIVE
drives the bar selecting device.

H BAR INSERTING DEVICE
takes the bars and arranges them into the guide channels.
L CLAMP AND BAR PUSHER UNIT
inserts into and removes the bar from the collet.
Furthermore, it inserts into and removes the bar pusher from guide channels.
M FEEDING DRUM
inserts bars into lathe.
N CONTROL PUSH-BUTTON PANEL
controls all bar feeder functions.
P HYDRAULIC CONTROLS
adjust hydraulic oil flow.
Q RACEWAY
houses the lathe cables.
R CUBICLE
fits the electric switchboard.
S REMNANT RECOVERY TANK
collects bar remnants.
T HYDRAULIC OIL PUMP
produces pressure for the hydraulic functions of the bar feeder.
U LUBRICATING OIL PUMP
produces pressure to lubricate guide channels.
V HYDRAULIC OIL TANK
contains the hydraulic system oil.
Z LUBRICATING OIL TANK
contains the oil for the lubricating system.

2.3 WORKING CYCLE - GENERAL DESCRIPTION
SIR MS32 P
- Bars, loaded into magazine (A) manually, are taken by chain traverse device (B).
- Bar inserting device (D) introduces them into drum (C).
- Clamp device (E) inserts the bar into the bar pusher collet.
- Then, bars are fed into the lathe.
SIR MS32F
- Bars, previously loaded into magazine (A) through a lifting device, are selected by bar
selecting device (B).
- Bar inserting device (D) introduces them into drum (C).
- Clamp device (E)inserts the bar into the bar pusher collet.
- Then, bars are fed into the lathe.

2.4 SAFETY DEVICES
A INTERLOCKED MOBILE GUARD.It is associated to
microswitch (B):
- when selector is turned to , the bar
feeder stops by opening the guard;
- when selector is turned to , the
bar feeder does not stop by opening the
guard, but there are few controls enabled,
i.e. those necessary for setting up or change
the machining procedures; they are:
.
C AXIAL DISPLACEMENT LOCKING.
It is associated to sensor (D).
By releasing the lever, all lathe and bar feeder
functions are disabled.
E INTERLOCKED MOBILE GUARD.
Associated to microswitch (F).
By opening the guard, all lathe and bar feeder
functions are disabled.
G INTERLOCKED MOBILE GUARD.
Associated to microswitch (H).
By opening the guard, all bar magazine functions
are disabled. The bar feeder keeps feeding the
lathe until the feeding drum runs out of bars.

2.5.1 Noise levels
The bar feeder does not cause acoustic noise.
Noise occurs when lathe, to which the bar feeder is connected, is running and the bar turns into
the bar feeder guide channels.
In such a situation, the noise level emitted depends on the following conditions:
- perfect alignment and levelling of the lathe-bar feeder unit;
- correct fastening of the lathe and bar feeder to the ground;
- perfect working order of the lathe bar gripping device;
- use of guide channels and bar pushers whose dimensions are suitable to the diameter of the
bar to be machined;
- use of a front guiding bush of suitable diameter (if supplied);
- use of bars whose straightness is within the prescribed limits (max. deflection in mm equal
to 0.5 per thousand of the bar length);
- use of a spindle liner with a diameter equal to the bar feeder guide channel diameter;
- spindle rotation speed suitable to the material to be machined;
- as far as the bar feeder is concerned, use of suitable oil, according to the diameter of the
bar to be machined;
- all bar feeder guards must be closed.
If the above mentioned conditions are complied with, the noise level emitted during the bar
rotation into the guide channel and measured according to the international standards, does not
exceed the following limits:
- brass and steel round bars ............................................................ within 80* dbA
- steel hex. bars...............................................................................within 83 dbA
- brass hex. bars..............................................................................within 85 dbA
The noise level is affected by the actual conditions of the lathe to which the bar loader is
applied as well as by the type of bars.
The operator should check if wearing personal protection equipment is required based on
regulations in force in the country of use applicable to work environments.
*) Measurements taken with Ø 35 mm round bar, Ø 36 mm channel < 5% straightness at 3750
rpm with lathe Index MS52 Serial number ..........
