    Don't get Diagnostics and Diagnostic Parameters confused. The 0 series control muddies the water in this regard because the parameters that are often referred to as Diagnostic Parameters are really...

    It's been electronic since before many here on the forum were born. 1970s if not earlier.

    It's a crying shame that forum members had to jump in and reply to the OP. Would have been much better for the forum to have let this one die a quick, un-replyed to, death. Maybe better yet, have...

    They are specialized machines and very expensive. Not many job shops or small manufacturers can justify one.

    I got a budgetary quote for a Taiyo Koki vertical grinder 10 or 12 years ago as part...

    Please post what the alarm was. I have an alarm list for Fanuc PMC-N. This is different than the PMC in the 0i controls but Fanuc are typically good about keeping alarm numbers and descriptions...

    Mitsu hardware is fine. It has been a popular choice of builders that want to do their own U/I and special features. Mazak and Citizen are good examples here. Most would agree that those...

    Like most builders, Kitamura has stepped on their dick a few times. If someone gets one of those poor designs, it will taint the brand for a long time. Their "tilt-a-whirl" tool change arm on the...

    Glad that you found it.

    If you look back to post #4 you'll see a request to find out what you had already done to trouble shoot the problem. Had you done that, myself or others would have asked...

    I have seen a few cases where the magnet inside the little sheetmetal clip on the spindle has broken. This makes a weird pole arrangement and causes irregular orient positioning.

    IMHO, one would need to look very closely at a used Robo or Brother. By far, the largest use in is very high volume manufacturing. Hours and cycles pile up very quickly in that environment. Would...

    Hey Dan, that's a nice little tool! It may work on Garwood's machine, but IIRC, the motor is on top of the machine on the larger machines. The attachment used at the factory was similar to what you...

    Man, you must be more cat-like than me. I run the last couple inches of rapid approaches at 5%. 25% is still nearly 500IPM and I sure as heck am not fast enough to prevent a crash going 500.

    IME, it still runs too fast to see what is really going on sometimes.

    At the factory they have a little handwheel driven gearbox with a "brake" that bolts on in place of the motor. This allows...

    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.

    Does yours have a spring under the cap that pushes the tapered plunger up when the arm moves down? I've seen that spring break and cause tools to be thrown.

    21.4 being 1 confirms the physical e-stop circuit is good. To check the logical (PMC) e-stop look at Diagnostic 121 bit 4. It should be 1 if everything is good with the ladder. If it is 0 then you...

    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...

    You should also check ballscrew and nut assembly and thrust bearings. I've seen problems there result in wavy surface finish due to the motor having a varying resistance to rotation.

    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...

    Have you verified that the servos are not hunting while stopped?

    Does the machine have scales? Mechanical backlash in a scale equipped machine can show up as waviness in a cut.
