SFPM/Spindle RPM Conversion Table

To find correct RPM to use, match the wheel diameter in BLUE on the table and the SFPM in RED on the table.

ex.  2" diameter wheel at 6,000 SFPM = 11459 RPM 


*Recommended optimum grinding SFPM for diamond and cubic boron nitride wheels: Dry - 4000 SFPM; Wet - 6000 SFPM
