ALPHA 538/552
1. BAR MAGAZINE
Please read the safety instructions provided at the beginning of this manual before
handling the following devices.
1.1. Description
The barfeed ALPHA 538/552 is equipped with an internal,
gravity-fed loading ramp. Depending on the length of the bar
feeder (3M, 12', 4M), the bar magazine may include six or
seven supports. Each support includes a loading ramp unit
with a fixed inclination.
When the new bar loading cycle is started, one bar is lifted
over the stopper, rolls over the dropping fingers while the
fingers move down.
The bar is placed into the guiding elements, ready to be
moved into the spindle.

The bar stocks are installed for machining by following these conditions:
- Lay the bar stocks on the loading ramp (

), each one besides the other (not one above the
other);
- Make sure the bar stocks rest against the rear limiter (
A
);
- Lower the upper limiters (

) so that the clearance left allows free rolling of the bar stocks, but
prevent bars jumping over the others;
- Set properly the bar selection (
