Calculate Ballnose Cutter RPM Same as Endmill
Jul 30 2010 · As tool presure goes up you need more rigidity If you cant get it youve got to slow down rpms To sort of answer your question you have to go as slow as you have to go If that means 50 rpm than thats what you have to do Doesnt matter what speed and feed calculations you come up with from info out of a book or whatever

What it is the optimun speed for a ball mill
Oct 19 2006 · Calculation of optimum speed depends on knowing the media diameter and jar ID also For instance if your jar had in inside diameter of 90 mm and your milling media was 127 mm diameter lead balls the optimum rotation would be 98 RPM Optimum RPM 65 x Critical speed cascading action of the media stops
Variables in Ball Mill Operation Paul O Abbe
The formula for critical speed is CS 12π √gRr where g is the gravitational constant R is the inside diameter of the mill and r is the diameter of one piece of media This reduced to CS 26545√Rr Dry mills typically operate in the range of 5070 of CS and most often between 6065 of CS
