Good job, Dave! These look very professional!

Thanks for showing.

Hi Steve,

Just wondering what kind of bearings do you have on your mill spindle and how is it cooled to run at 8500RPM?

And I have been always wondering what that Multi-Pass wizard was... Will know now. Thanks!

Wow! A 60ft. long mill, that's some serious piece of machine! 12 hours for aligning this monster looks like no time

Thanks for the details. Though I am still not sure I understand how you use the collimator to benefit its behaviour

Nice work Rich! And like you say, somewhat unusual.

What do you use the collimator for? Just curious.

Depending on your spindle motor, you could use an ammeter to reflect the load on the spindle. Pretty easy to add on a DC motor, not as so on other motor types though.

Hood,

Thanks for link. Only information I've been able to find on it is this

http://sensor.baumerelectric.com/productnavigator/downloads/Produkte/PDF/Datenblatt/Winkel_und_Positionsmesssysteme/en_E_1DG_BDK.pdf

You've probably seen it already. Looks like the same encoder just a newer version. So looks like it does rated at 12,000rpm, but it is only 100PPR so I am not sure how will the motor perform at low speeds. Also it is 10-30VDC so would require some interface.

Yes, Hood, a lot of info there, but it worth the time to read

OK, I think I understand it now
