I'm converting this machine to CNC and will use a VFD and new 3 phase motor for variable speed. There a several ways to skin that cat, resulting in a wide range of possible spindle speed ranges. I'm thinking that it would be nice to have the option of getting to around 3000 rpm, only for occasional use on small diameter parts. Can the bearings take this, with the understanding that most use will be well inside of the 2000 rpm that the stock machine maxes out at?
