How funny is this?
This is my setup...
just changed my coolant with "TRIM SC520" and this is some thick stuff. I only mixed it 5:1. Anyone else use it? I normally use astrocut synthetic

Yes, i have been using it for about 6 months. This pic was taken while still in the build stage.
It is using Clearpath servos on all axis and Mach3 with ESS/MB2.
Pull studs were an issue, but now i just purchase ones that are slightly larger and machine them down in the lathe.
I will post some more pics/vids later.
Oh gotcha. I did find holder that fit these spindles. Idk if you need anymore but there made by armada tool

Thanks,
I have looked at those, but they are a bit pricey...
I've been using some of these for the light work:

Does anyone use shrink fit holders?

Finally got the tool changer functional and almost done. I ended up swapping motors again. I didn't want to worry about heat so I put a newer Colombo motor on that has an hsk 40 taper.

Very nice implementation on the tool changer. I like how the tools and holders move way out of the way at the end of the cycle, very well done.

Thank you. I still have to o make some kind of cover for the top of the holders. I never thought too much about it but being hsk holders, there a hole in the middle for the fingers on the motor. That's a great place for shavings to pack in and no way to get them out.

It’s been a while since I’ve posed anything so I figured I’d take a video while I’m sitting here watching this thing run.
This is a 1/4” depth of cut at 11000 rpm with a 10mm bit

FYI the spindle should still be able to run at top speed when run at a lower voltage, just with less power than when run with the correct voltage. For example, if you've got a 380v 8HP spindle that has a rated speed of 18k and max speed of 24k and rated current of 14A, if you ran it at 220V, you would use a 220v VFD (don't try using a VFD rated for a different voltage than what you've got, it'll fault,) you would set the current to the same 14A, but set the nameplate speed (or whatever it's called in your VFD, the speed where you reach max volts,) to 10,400 RPM (18k * 220/380,) max RPM to 24k, and your max power would be 4.6HP. Torque up to 10,400 RPM would be the same as the constant torque of the spindle running on 380 (which would be constant torque up to 18k.) You would then have constant 4.6HP between 10,400 and 24k RPM.
This only applies to water cooled and forced air cooled spindles. Spindles that have a fan on the spindle shaft (most air-cooled non-ATC spindles) would need additional derating due to reduced cooling at lower RPM's.
