Hello, I am looking for the best way to upgrade my current cutter to achieve a better finish on a cast iron head for a mls gasket. I currently have carbide cutters (15) on a 16" wheel, the spindle rpm is roughly 80rpm and the feed speed is set by my motor rpm (860) driving the ball screw. If i go from a 3 5/8 drive pulley to a 6" i can get my spindle speed up to 132 rpm, Will this be enough to get me a fine mirror like finish with my current carbide cutters? or am i better off fitting a few cbn cutters on there and would my rpm be enough to cut smooth? Maybe somebody has already done this, very limited info on the 280 machine out there. Thank you for any replies guys.
Edit: so i dont screw up my cutters experimenting, what would the max rpm i could try with my current setup on a cast iron head? thank you
