i have started to repair vari drive on my Hurco SM1 cnc mill. mill is very noisy at higher speeds and doesn't change much when spindle is disengaged with high low lever. the top of the mill comes apart fairly easily and i found that all bearings are a little rough but none are really bad. i am going to replace them all and am wondering if i should stop there, or replace the spindle bearings too. does anyone know the procedure to pull the spindle apart on one of these old hurco's?
thanks
