    Hardinge GS51 Lathe, cutting wrench flats

    I'm running a Hardinge GS51 Lathe, Fanuc Series oi-TD controls. I want to cut wrench flats in the Sub Spindle. I have a running program that I'm using to cut flats in the Main Spindle. I didn't write it. When I try to run the same program in the Sub, It will only cut one flat, not four. Here's a copy of the program.

    N2(SIDE CUTTING MILL,MAIN SPINDLE)

    G50S2000
    G98(IPM)

    It is polar. are you really using a 3.0 dia cutter?
    What is the distance across flats you are wanting?
    The Z depth in the program is negative. I would expect it to be positive on the sub, unless it works different than I have seen before.

    how many boxes of #2156 will you give me for helping you?
