[QUOTE="Trickymissfit, post: 1064316, member: 25383"] Kadets share a few problems that virtually all CNC lathes have. Headstock alignment is a PIA on a good day with any of them, and the fix is the real issue. Okumas are some of the worst to realign out there. Monarchs are pretty bad as well. The older J&L's had the best frame ever, but in a wreck would loose their head stock alignment. About a three to four hour job depending on which model. An Okuma is typically a sixteen hour affair on a good day. Getting access to the dowel pin holes is the issue in all of them. The old Monarch TC1 was a two day affair! It's all downtime money that's lost forever. Turret alignment is a pain with all Okumas, but after you've done them a few times you get a lot faster. The real issue is the way they did the coolant system inside the cross slide. Never figured out why! They could have easily mounted the valve outside of the slide like everybody else. Trust me, these issues are minor compared to what you encounter with a Mori Seiki!! Okuma for some odd reason designed the electrical circuits for over travel and the zero switches extremely over simplified. Works great till something goes wrong. It then becomes a nightmare trying to figure out what axis failed, and whether it's over travel or the zero switches. Have pulled more than one new set of cables in them over this alone. First one we had to do this was down for the better part of a week just trying to find out what was wrong! The other big electrical issue is in their CNC control module. The operator has access to the parimeters, and this is an absolute no no! [/QUOTE]
