Anybody familiar with this machine? We are having a reoccuring problem on the sub spindle side holding size. On approximatly 1 out of 3 parts the OD and ID will finish .010 o/s. When this occurs we simply rerun the finish OD without offsetting and it will come out right on size. On this particular part, we use 2 turning tools, 2 1.5" boring bars, and 2 .375 Carbide E.M.'s. The two turning tools run on main and sub spindles and we use different tool offsets on the sub side. For Ex; T02002 for main and T02102 for sub. Neither our salesman nor any of their service techs had heard of this problem before. Any help or advice is greatly appreciated.
have you had some one check the backlash and gib tightness on this machine ?
