54 CHAPTER 4: OPERATION
MOVE S2
The bar feeder autonomy is depending on the bar stocks placed by the operator on the chain loader. This
task can be performed at any time in the production cycle, without needing to open the main access
cover.
Every time the automatic cycle is to be started, it is recommended to check following points:
On the chain loader, the bar stocks must be against the front limiter.
The guiding element must be adapted to the bar stock diameter.
The pusher must be adapted to the bar stock diameter, to the guiding element diameter and to the
spindle inner diameter (including spindle liner).
The pushing force must be adapted to the bar stock material.
On the lathe, the clamping device must be adapted to the bar stock diameter.
1. The bar stock on the chain loader is loaded on the dropping fingers.
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.
8. The pushes moves back by the selected value.
9. The automatic cycle starts, the parts are machined.
To each clamping device opening, the pushes moves forward, positions the bar stock for the next
part, then moves back by the selected value.
10. The cycle goes on until end of bar signal is given. At this point, the lathe enters a sub-program
and the pusher moves to reference position.
11. The pusher moves up.
