Mori Seiki MV Junior differences between spindle options

[Moriseikiman]

Hi, does someone here know if the 10k RPM spindle is totally different from the 6k RPM stock option (the bearings and motor and belt ratios) or did they just add some better cooling thing? I found a parameter that makes the 6k rpm version actually go faster and I would maybe dare to run it a bit faster than 6k if the bearings from the spindle or spindle motor aren't gonna go to toast. I'm playing it safe and run it only at stock 6K if it's built totally different. Maybe at 7k or so if there's not much difference to the 10k version.

I researched this for an MV65 I had and the 10k spindle was completely different from the other spindles.

The spindle motor was same, 6k rpm. The gear ratio was different.

Some MVJRs had spindle coolers as well- that could be a big difference.

All the high speed spindle versions have it afaik. But how different other than that
