Thanks Jeff for the info, started to learn a few more things about spindles

Are any other suggested spindles out there in the same price range as Wolfgang? (about $300)

Nicolas,
Suggest you just start looking at all the different tooling catalogs and see what you come up with. How to compare them is another story.
The prices run the range from say $50 to $1000 plus. You never know what's inside and just how they are made.
Example; ground end, balanced, high end bearings, hardened shafts, size of shaft and beaings, etc. Lets not forget the type chuck on the end or how the collet is made.
Kind of tough to judge the quality just on price.

Designing and making your owne is certainly an a good option.

LOL,
RICH

If you'll be doing any cutting at all, I'd get the Colt.

Love this topic.  I need to buy a spindle for I.D. grinding of 6mm holes.  I need to add a tool post grinder to the Emco CNC lathe I retrofitted with Mac. The spindles shown here look small enough to be fitted for the job. Any new ideas are welcome.

I think Little Machine shop sells a kit or a small one. Don't think the spindle has any adapters for small internal grinding. A smaller electric die grinder mounted on the carriage may be just as good and
is a whole lot cheaper and uses a collet for mounting of the stones. Makita sells one along with a fixture to hold it horizontally.

COMMENT: Sold my toolpost grinders. I think it's the worst add on a person can have for a lathe. The grind dust goes all over the place no matter how you
cover up the lathe. Clean up is just a PITA.

My comment .......your lathe, ;)

Thanks for the info.  Agree completely about PITA.  Its a bushing with 5mm hole that needs to be ground 8mm length, 62 Rc. tool steel.  Making initial trials adapting a ceramic insert to a boring bar but its all too small...... Need to hold 0.01mm.

Food for thought, Promech... If all you need to hold is .01mm, then making a jig for the mill, and plunging a carbide end mill might be an option, if most of the material is already removed and all you need is a finish cut. Obviously, you know allot more about the parts your holding in your hand, better than anybody on a forum. Figured I'd throw it out there, anyhow.

I thought that my Variable Speed Bosch Colt had an RPM range of 10K-30K but after reading the manual the lowest RPM is 16K which is too high for work on Aluminum and so I’m looking for suggestions for an 110ACV or DCV Spindle

I could get the Wolfgang AC Volts spindle and use my router speed control gadget to control the RPM and hopefully it will give me 2000-3000 RPM

Or I found this 3 speed (7500, 15000, 30000) spindle for $90.00 which it has a motor working on either 110ACV or DCV. I guess if I use the 7500 RPM setting and use my router  speed control gadget I should be able to get around 2000 RPM.

Any suggestions ?

Or modify the Colt with a SuperPID and it'll be usable from 5,000-30,000.

www.superpid.com

It'll also let you control spindle speed and on/off from within Mach3, with no additional hardware needed.
