    Default Need a sample 640t SQT100mst bar program, EIA, sub spindle sync?

    Hello,

    Just doing a simple bar program with a SQT100MSY, 640t.

    Turn the end
    sub spindle clamp & sync.
    reposition
    repeat
    We know how to part off and end work, we use a 9001 sub-program for that.

    Thank you!

    Mike

    Thank you very much, I am a little further on now, but what I am looking for the most is not in your program.
    Below is where we are at, spindles synced, pullout is complete, the issue now is that when I go in to machine another section of the bar it is not moving the Z zero with the bar pull, any comments?

    Your program is close but just looking at the spindle sync, that is M511 but whatever strategy I am missing is probably something pretty basic. We will need to move the part out 3 or 4 times, it is plastic and we are putting groves on the OD and at the end we will end work it in the sub.

    Only thing I can see, and I'm not sure it matters, is the G50Z line. I use G50 W-[#102]. Just be careful that it is shifting the offset in the right direction.

    Chad883,

    G50w, I have seen that and I will change it, thank you. My next problem is getting the spindles to stop tougher, they are synced but when they stop they seem to be do some kind of independent correction/c axis homing, I need to fix that, any hints?

    I usually sync them with 1 of the chuck open so they don't fight. May not be necessary.
