Quickly becoming a favorite YouTube channel. It's increasingly high level work. Thanks, Uwe.

Nice! I like the design and the construction method you used to achieve rigidity.

Well done.
How are you liking your spindle and what speeds does it run?

Our Hitachi Seiki slant bed has a hydraulic tool changer. I mapped out all the functions and had the wires connected and ready. Mark (cncsnw) programmed the PLC. Wise $ spent. I think I could send you the code as a sample but have Mark help you as timing and other details are critical. Been working ...

Ah. Perfect. Thank for the clarity in that. Seems like half the battle is getting the terms right; "axis summing", in this case.

Are there any pitfalls with using two servos to contribute to one axis of motion? Example is one servo driving a milling quill downward and the second, driving the knee upward. Goal is maximizing available travel. Centroid already supports dual servos for bridge mill / gantry type situations. Nice. ...

Nice. Researching both now. Will follow up soon. Thanks, fellas.

Thanks, Mark. Sounds like the mechanism the page refers to is a clutch, then. We'll plan accordingly and be in touch with you if you've got room for the work and don't mind the travel.

What did you end up doing on this project? I'm on a similar trail for two machines. Having researched it out, I'm surprised that there's not more support for C-axis / mill-turn conversions on the CNC aftermarket or more explicit direction from Centroid. Siemens, Fanuc, Mazak and Okuma seemed to have...

I did a 1986 Hitachi Seiki slant bed lathe 9 years ago (with cncsnw batting clean-up with me) and it's been an unequivocal success as a daily driver in a production environment.

Very similar in design to your Mazak - and color.... love that green.
