SPRINT 545/565S25
8. AUTOMATIC
CYCLE
Please read the safety instructions provided at the beginning of this manual before
handling the following devices.
8.1. Description
The barfeed autonomy is depending on the bar stocks placed by the operator on the loading ramp. This
task can be performed anytime in the production cycle.
Every time the bar feeder automatic sequence is to be started, it is recommended to check the following
points:
On the loading ramp, standard bar stocks must be against the rear limiter.
The guiding elements must be adapted to the bar diameter.
The elements of the front rest can be adapted to the profile of the material.
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 bar feeder collet must correspond to the bar diameter.
The pushing force must be adapted to the material being loaded.
On the lathe, the clamping unit must be adapted to the material being loaded.
8.2. New bar stock loading
1.
The bar stock on magazine is loaded using the cylinder loading into the guiding elements.
The pusher is in the fully retracted rear position and the pusher guide is open.
2.
The loading finger moves forward and pushes the bar to the measuring position.
The bar length is measured.
3.
The loading finger moves to the fully forward position and inserts the bar stock in the lathe spindle.
4.
The loading finger moves to the fully retracted position.
5.
The pusher moves down into the working position.
6.
The pusher moves forward behind the bar and finishes the positioning of the bar in top-cut position.
7.
The lathe’s clamping unit closes.
8.3. Part
feeding
8.
The pusher moves back by the programmed value.
9.
The lathe's automatic cycle starts, the parts are machined.
At each clamping unit opening, the pusher moves forward, positions the bar for the next part then
moves back by the programmed value.
8.4. Remnant
extraction
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 remnant switch (SQ12).
11. The collet clamps the material and the pusher moves to the fully retracted position.
12. Once the pusher is fully retracted, the collet releases the material and the remnant falls into the tray.
13. The pusher moves up.
