Thread: Chinese Spindles
Making an ATC system for 6000rpm is a lot less challenging since, to an extent, balancing is no longer an issue. Also you can use much bigger/stronger angular contact bearings than at 24krpm which makes the design much easier. Still not saying it's a straightforward project, but I'd consider it as even though that spindle is a good price compared to the rest it's still a lot of money to spend...
For motors you've got lots of options at 6000rpm. Most standard induction motors will overspeed quite a lot, so a 2-pole motor and a belt will give plenty of power and options. However they're rather heavy and bulky.
The motor I used on my micro lathe is actually ideal here:
[That's odd - it's dissapeared from www.hobbyking.com, it was called 'Turnigy 80-100-B 130Kv' ... I'll email to find out where it's gone, hope it's not discontinued. They're available elsewhere but more expensive. http://endless-sphere.com/forums/vie...?f=28&t=39779]
Being rated for 6.5kW (as if!) means you could probably afford to run it direct drive and still have plenty of power at 1000rpm, athough it would still be better to have two ratios. Probably 3:1 and 1:1.

I'm looking at at least one maybe two of these BT30 atc spindles, so when you're looking at getting yours let me know. A better search may provide a better or cheaper product so don't rush into this one.
I also looked at the spindle with the motor, but i need to use 6k or less for mill use.
I'll have a better look later as router is running at the moment...
