    Help with SuperMax YCM-TC-2 CNC Lathe ...

    Anyone have any experience with the SuperMax YCM-TC-2 CNC lathes? Looking for any help anyone can provide. Don't have a lot of CNC lathe experience, so any help is appreciated.

    We are in the process of trying to get an older SuperMax YCM-TC-2 lathe running. It's a 1994 machine using Mitsubishi controls. We have the Mitsubishi manuals but little to no information from the vendor (Yeong Chin). It was obtained from an old warehouse and we really don't have any good idea that it still works. We've had to replace a few boards and the backup battery and have managed to get it moving in the X & Z axis but have not been able to get the spindle to turn (just using in jog mode at the moment). Should the SPINDLE JOG button move the spindle when in Jog mode? We're assuming it should, but the spindle doesn't move. We can move the chuck in/out. We can also see RPM info on the spindle screen when we manually move the spindle so at least there's some feedback present. We're not getting any alarms on the NC or directly on the Spindle control (Mitsubishi FR-SF) but the spindle does not want to move. Any ideas?

    We're also having some trouble with the tool change turret movement. The machine has an 8-tool turret and when we use the TURRET INDEX button, the turret just continues to move, it never stops. Not sure if that is normal with the TURRET INDEX button in jog mode. Any ideas?

    Again, appreciate any help.

    The turret home prox switch is probably bad.
