Supported round rails and C5 ground ballscrew
I have 25mm supported round rails on all 3 axis of my CNC router (for aluminium) . At the moment I have 16mm C7 Chinese ballscrews.
If I were to upgrade each axis over time (for affordability), and go ISSOKU C5 ground ballscrews / BK15/BF15 bearings. But keep the supported 25mm round rails and bearings will this make a good improvement ? I don't really want to spend the extra money to buy linear bearings and rails. But would this (in layman terms) be like buying road race wheels for your car and putting dirt tyres on them ? or maybe it would be a big improvement over what I have now ?
The goal I suppose is limiting tool chatter and improving finish on aluminium.

Hi Dudz
I don't have a machine but have done enough reading of the extensive knowledge available on the forum, IMO i think you would be better served by the linear rails, i feel this would considerably stiffen the machine.
Good Luck
Mike

No point going with expensive screws and keeping round rails.
Profile / square linear bearings are FAR superior to round rails
