    Default Nikken rotary Brother A00

    Hello again. I have got a lot of work ahead of me on this one. Just making a thread for progress pics, questions and hopefully some advice along the way. I have a Nikken CNC 100a (circa 2001) rotary and support almost ready to plug into my A00 brother (TC22-A). A bit nervous to start messing around in the control cabinet but oh well.

    Here is a bunch of pics, in the wrong order. I will update when I get more done, any questions I will gladly share what little I have learned.

    1st order of business is to machine the motor gear from the old fanuc motor to fit on the larger Sanyo motor. Once that is done I can design the new motor cover housing.

    Is the encoder count on the Sanyo motor compatible with a rotary axis ratio or does the Brother control have an "electronic gear ratio" type function?

    The gear ratio can be defined in the machine parameters.

    Turns out this gear is 55-60 HRC. Not too worried about the bore, but that keyway will be tough. Luckily it is .189” wide so I’ll be able to plunge most of it out with an end mill. Going to try to grind a carbide broach to pick the corners square

    So gear is done, EDM keyway. Everything is temporarily plugged in and a few things are amiss. Servo error for parameter for A axis, and unable to clamp A axis. Imgur: The magic of the Internet
    According to the manual, Imgur: The magic of the Internet
    it has to do with motor type and limit of current while preventing drop due to dead load. So far have not been able to find anything on where these would be altered. The clamp issue will probably be a different clamp type but I’ll get there next.

    Well, it’s spinning! Spins! - Album on Imgur
    Far as I could get today. Next is to machine the enclosure Enclosure - Album on Imgur
    The hand pendant doesn’t work though, says select axis when I turn it to the 4th axis, maybe need to name it in parameters, not sure. Also need to set grid and check the health of the mechanicals.

    To select Axis for the jog handle, go to the Manual Conditions screen, at the bottom you select the axis.
