    Re: Removing the spindle pulley

    Yep shortly after I posted I found the info about it being a shrink fit.
    A little heat and I did not even need the puller just a leather glove, it lifted right off.

    Thanks,
    Andre

    Removing the spindle pulley

    Is there a trick to removing the pulley (ER16 spindle) from the spindle?
    I have removed the setscrew but it is not moving, not sure how much force should be needed.

    Thanks,
    Andre

    Does your program activate a tool length offset?
    Look for "G43 Hn" just after a tool change.
    If you are touching off the end of the tool the tool length needs to be zero or not active.

    In my opinion the 3/8 end mill would be a better tool for this job.
    A carbide 3/8 end mill will also very likely get you a high metal removal rate.
