4. BELT

DRIVE

4.1. Description

The belt drive is controlled by the servo motor (

), which controls all the forward and reverse

movements of the pusher and the positioning of the bar, and the insertion and extraction of the bar in the
collet.

4.2. Layout of the elements

4.3. Belt

It is possible that after a certain amount of use, the bar feeder belt

(A)

will need tensioning.

During the intervention, the belt must remain tensioned. If the belt and the notched pulley
are misaligned, the motor will lose its reference points. If this occurs, please contact
technical support.

Procedure:



Bar feeder in STOP position.



Open the protective grille and the protective cover.



Undo the retaining screws (

) from the return pulley (



Using a torque wrench, adjust the belt tensioning torque to 5
Nm using the lateral screw, as per the table below: (



Once the tension has been adjusted, retighten the retaining screws

(A)

for the return pulley
