65mm water cooled spindle reduce the integrity of travel and bearings?
I was able to mill on a 0.25” 440C stainless. It was kind of rough due to the minimum RPM the router has (9600 or so) but worked. This RPM range is too high using small diameter carbide on harder materials. I need to get around 3-4K.
I would like to upgrade the spindle to a 65mm water cooled which allows the lower RPMs needed for metals like this. I believe the weight is around 10-12 lbs and will slide right in.
Before making this purchase, will this weight reduce the integrity of the bearing and travel bars?
Is this a good question?
