    TC Series Yaskawa Motors on Z

    Does anyone know the model number of the Yaskawa motor on the Z axis of the Torq Cut machines? I am trying to find out what KW rating it is.
    Was it belted to the Z axis ballscrew at 1:1?

    Are the X/Y Axis Yaskawa motors the same or different than Z?

    Did any of the TC Series machines have a counter balance weight on the Z axis? I know the TC22-30 did not. This would make a difference in the size of the Yaskawa motor on Z

    Thanks in advance!

    The Yaskawa servo motors are 1300w for X Y and Z the drives are 1500w Z axes Ballscrews 5mm pitch 1:1 Ratio no counter weight on the small machines, on the larger machines they have a 30 tooth on the motor and a 36 tooth on the Ballscrew

    If you are loosing oil you can replace the seal at the bottom, they can be run without the Transmission if you don't need it, there are parameters to change a little wiring and the special motor pulley to change, I have not done any of this work for a long time my business friend still has parts I don't think there are any new gearboxes left I think the last one was sold a few months ago there will possibly be some gear box parts though

    Gear box has to come off for the seal. I just got the oil today. I'm going to fill the box and see what happens. Run a warm up cycle and then start shifting gears and see if it can shift ok.
    If not, I may just remove the gear box. If your friend has the pulley and belt number that would be helpful.
    There is an off chance I know where a gear box is...

    I will be upgrading the control in the next couple of months. Going from DC Brush Servos to AC servos and Centroid Control. Doing all the prep work now....

    Hi Mactec,
    Seems as though with the gearbox filled up, its not missing anymore shifts. I have to test it some more...after over a week the oil level is still in the same place on the sight glass. Don't see any oil under the gear box in the drive belt well. Wondering if the previous owners ever checked it.
    I'd still be interested what it would take to remove the transmission, if I so choose and direct drive the spindle. The spindle motor seems to indicate its an 8000rpm motor. I am wondering if the motor pulley is 1:1 with the spindle or slightly smaller.

    Thanks
    Marty

    Marty, Did you ever buy the AC servos for this machine? If so, what was the specs on the ones you got? Also what is the mounting configuration?

    thanks,

    Jim

    I did not. I had purchased new AC Servos for the machine and then found a newer Atrump Maximill E216 with a Centroid control.
    I sold the TC22 to a new owner who completely disassembled it, refurbished it and has it moving again with its original control. He will do the upgrade to new AC servos and a new Centroid control.
