OPERATION
3.40
You are able to manually operate the Barfeed’s basic functions through the screen.
ie Loading Cams
Cross Slide
Insert Pusher
Main Pusher
This just simply allows the operator to manoeuvre the positions of the working
functions for whatever reason.
After set-up, the pushrod pushes the material forward as requested by the Lathe
until the bar is fed to a Lathe stop. When the collet/chuck closes, the push rod will
retract to a variable distance (or will retract fully if full retract function is selected) so
that there is no contact with the pushrod and the material during turning, this intern
prevents vibration.
The pushrod will repeat this cycle to the point at witch the Barfeed will generate a
signal to the Lathe to state the last component has fed out.
After the last component has been depleted the bar end will be ejected from the
collet/chuck by the newly loaded material or by the push rod, the push rod will then
fully retract. When the push rod is back, the cams will rise to load material into the
supporting channel then the cross slide will traverse so that the channel is in line with
the spindle.
The insert pusher will push the new material along the channel and will pause for a
short period once the Barfeed has detected the front end of the bar, the bar will then
be fed into the spindle, when insert pusher is at full stroke, it will then retract and its
at this point the Barfeed will detect weather or not material has been loaded! if there
was no material loaded then the Barfeed will activate an alarm and generate a
magazine empty signal. If new material is loaded then the Cross Slide will traverse so
that the pushrod is in line with the spindle.
The pushrod will push the new bar against the Lathe stop and a new turning cycle
will start.
Full retract and Single bar is selected on the auto monitor screen that is only
displayed after auto set-up stage is completed.
If single bar is selected then only one cycle operation is carried out and will not
reload any more material and will generate an alarm after the final component has
been depleted.
The reload sequence is totally controlled by the Lathe.
