5. AUTOMATIC CYCLE

The bar feed autonomy is depending on the bar stocks placed by the operator on the loading ramp. This
task can be performed during the production cycle, unless the end of bar has been reached.
Prior to starting the automatic cycle, it is recommended to check following points:
On the loading ramp, the material must be loaded against the rear limiter.

5.1.

New loading bar stock

1. The bar stock on magazine is loaded using the cylinder loading into the guiding elements.
The pusher is in back position, lifted up and the pusher holding system is open.
2. The loading flag moves forward and pushes the bar stock in measuring position. The bar length is
measured.
3. The loading flag goes on to maximal forward position and inserts the bar stock in the spindle.
4. The loading flag moves back to maximal back position.
5. The pusher moves down in working position.
6. The pusher moves forward to the bar stock and finishes the positioning in clamping position (top-
cut).
7. The lathe's clamping device closes.
5.2.

Part feed out

8. The pushes moves back by the selected value.
9. The automatic cycle starts, the parts are machined.
10. To each clamping device opening, the pushes moves forward, positions the bar stock for the next
part, then moves back by the selected value.
5.3.

Remnant extraction

11. The cycle goes on until end of bar signal is given. At this point, the lathe enters a sub-program
