wow! thanks for posting. impressive machine and installation. nice work!
do you have any video of it running a job? would love to see it in action.


Here is one of us machining a pocket with and end mill in the live tool holder.

We have recently finished up a major retrofit on a Cincinnati Avenger 250MT 3 axis lathe. This machine was originally controlled by a Acramatic 850SX IDS control that is supported by Siemens USA. It had a couple issues with it when we picked it up that made us want to do a Retrofit on it. Firstly ...

Here is a report from the machine. In addition it has a SGDV-170A01A servo drive and a SGMGV-20A3A6C servo motor on the x axis and a SGDV-330A01A servo drive and a SGMGV-44A3A61 servo motor on the z axis.

Let us know if you need any other information.
Thanks

Folks,

We're consistently getting sub-par threads and are noticing a visibly jerky Z-axis motion when the threading insert gets deeper into the threads.

Motion while cutting the threads near the OD are fine. Also, threading speed doesn't seem to matter much.

System is an Oak, circa 2013. Heavy ...

This would also be e super useful not only for mill-turn machines but also gear hobs and other highly synchronized operations.

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 ...

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