## Ball Mill Calculation Kw And Rpm #### How to calculate the RPMs and Speeds using as slitting saw ...

· Example the value for cutting with 4" silting saw in steel would be 100 RPM but on my mill 200 RPMs is my lowest range. So I set it at that lock everything I can down as best I can and put lots of coolant on it. I would make the cut with conventional milling since my mill is no where near rigid enough to do climb milling.
