The ISO30 ATC spindle has a cost of 1300€ to me, with the sales tax paid, here in the EU.
I import my own stuff, and can include extras in each lof, if someone wants some.
These usually arrive about once per month.

The spindle has 7000 rpm bearings, theoretically.

Im not sure, actually, what I will use to power it.
I will probable get a servo, and I will probably need to order it with the next lot of stuff.

My bridgeport mill 3-phase motor works.
I have a spare 2.2 kW VFD.
A new motor (second hand) is very cheap.
So, for maybe 100-150€ I can get a 2-3 kW motor, and I might do that to try.

I dont have spare, large, servos, only 750 and 400W ones, atm, but this changes.

I very much wish to do rigid tapping, and high-speed accelerations, ie servo.
Yet, a 2-3 kW servo is about 1600€.

The spindle should handle 5-7 kW, theoretically.
My machine frame, hopefully, will do 3 kW.
If it does, I will be Very Happy.

Anything above 1 kW cutting power is fine, for me.
The machine is very large re_frame, but I dont expect to do major metal removal. If I do start doing so, then a big servo is the first thing.

Hannu where are you buying Iso30 spindles from @1300euro.? Also what rpm bearings.? I presume your using a Servo to power it.? If so what size and RPM.

Hows the Lathe upgrade coming along.? I'd like to see this working when it's finished so please post a video. Also the mill. .
