    Hello

    We want to equip the counter spindle with live-centres to turn longer parts.
    Unfortunately this does not work.
    The machine moves forward and the pressure is building up but then it just stops...
    no idea why.
    Has someone already had such a problems?

    I would be grateful for any help.

    Kind regards

    Morning

    How have you have programmed it? It would be nice if you could post your program or send it to me.
    We have built in revolving tail stock centres with pressure-balancing into the counter spindle. Then I wrote a subprogram with a context menu, in there the machine runs up to 2mm prior to the dimension in rapid traverse. Then it drives into the centring in feed motion.

    Here is the subprogram:

    %countersp.ncs

    [parameter description for the display:]
    [//]
    [max.TL 1234567890123456]
    [la=1; s=Position Spindle]

    [//]

    N1 #31=#__la
    N2 #32=#31+2

    G1 Z#31 G94 F75
    G4 F1

    RETURN

    Kind regards
