What is different between the minimill 6K and 10k spindle on the super mini?
Which one or all of the following would have to be replaced to upgrade a regular minimill to a 10K? Same question for a 15K

1. Spindle Cartridge?
2. Spindle Drive?
3. Spindle Motor?
4. Pulley ?
5. Belt?
6. Parameter Change?

Thanks,

Easiest way to upgrade from 6000rpm to 10,000rpm is load the slower machine on a big trailer and tow it away then day put a new 10,000rpm machine in it its place.

Yeah, I know, I know, I am being a smart ass but it is a good idea to start the year on flippant footing I think.

The 10,000rpm has a totally different DC power supply and a larger motor. As far as I know the spindle is the same.

Happy New Year

I am pretty sure the bearings in the spindle would be a different class bearing
to handle the rpm and spindle might be balanced better

hope this helps

On the VF-3, at least, the 10k spindle doesn't have a gearbox...but for all I know, the minimill doesn't have one on the 6K. ;)

My VF-2 has the 10K spindle and the gearbox. It was available. It's the 12K that doesn't have the optional gearbox.

Must be nice. The -3 that I run most often at work has a gearless 10k and NO torque. A 4-inch, .060" slitting saw, cutting .250 deep, will stall the spindle. Still, it does a great job running at 10,000 rpm and 500 ipm in graphite. Just gotta use it for what it was made for. :)

There are 2 10,000 RPM spindles for the VF line, one is a 20 horse, one is a 30. The 20 horse is available with or without the gearbox, the 30 only comes with it. The super mini mill 10K spindle is a 15 horse with no gearbox option.

I'm only talking about 40 taper VF's...the 50 taper 10K stuff is different.
