Triac Spindle Speed Upgrade

Hi All.

Is it possible to upgrade the spindle speed on the Triac to (for example 8000rpm)?

I have seen a video on YouTube where a Triac Fanuc was upgraded to 10000rpm by fitting a Chinese 2.2Kw spindle motor and a radiator/pump to cool it.

Would the spindle bearings be capable of this speed?

Hi Brian. With a 3:1 reduction you can get 8000 rpm from the chinese spindle and the bearings are close to the max op speed. I would replace the bearings with better ones to be on the safe side.

Is it a big job to replace the bearings?

I wouldn't mind getting a third Triac VMC to make several upgrades to.

fairly easy job, nothing about this end on the vmc.

What would be best bearings to replace with (source).

Would be nice to upgrade to triple stack steppers to increase rapid feedrate.
