    IME, the breaking 30 taper pullstud "issue" is overblown with regards to heavy cutting or long tools.

    Shop I retired from had at one time, four 30 taper machines. Never had a pullstud break.

    Is Diagnostic 21 bit 4 0? If so then you have an e-stop condition. Doesn't necessarily mean an E-stop switch is pressed, it can be anything the machine builder wanted to connect that would e-stop...

    I think there are some big differences in machine design as to how well they clear chips. My personal machine washes down well and chips never pile up badly in the enclosure or around the vise. ...

    For me, with 98% 6061 workpieces, I would rough and finish with the same tool unless there were some really tight dimensions to hit. Even then I'd still probably use the same tool. Solid carbides...

    It could do the physical axis with a servo controlled boring head. That's an easy one.

    It could also do similar to the Okuma turn cut, but could not use the spindle as spindle motor control was...

    It's really only been widely applied in specialty machining operations. Large valve manufacturing is where I first saw programmable U axis on an HMC. At a GE engine plant I removed a boring mill...

    If you buy a control from a salvage machine that was 4th axis, you will have to have Fanuc come out to load the option parameters. Won't have to buy the options, just pay for the service call.
