10.1 AIM OF THE PRODUCT
Thanks to the use of a drilling machine it is possible to drill the end of a bar automatically
before it is loaded in the bar feeder drum.
The end of the bar being drilled, it is possibile to hold the bar by means of a pipe gripper and
to use a bar pusher the diameter of which is as large as the bar diameter, or even smaller; in
case the diameter of the bar pusher is smaller than the diameter of the bar, the spindle
reduction tubes should fit the diameter of the bar and not the diameter of the bar pusher.
The bar can be thus precisely fed; oscillations and vibrations caused by rotating bars, which
could cause damages during workpiece machining, can be dampened.
