I do 13" parts on a HAAS HL1BB all the time. It only has a 10" chuck, so the part overhangs and you can't use a stick tool because there isn't enough clearance outside of the turret. I'm using a KM type holder in a broing bar holder to face, turn and profile the OD. It works just fine.
I turn 14" + parts in my Mazak Integrex with an 8" chuck on a regular basis as well, but the parts only fit on the sub spindle. |
