Machinist can calculate CNC Mill (Lathe) spindle speed in metric units using this formula:

Sn = 318.3 * Sp / D;

where
Sn - CNC machine spindle speed, revolutions per minute (r/min),
Sp - peripheral speed in feet per minute (m/min).,
D - diameter in mm (cutter diameter for milling or part diameter for turning).

 

To calculate the CNC machine (mill, lathe) spindle speed, enter the  peripheral speed in meter per minute and cutter diameter for milling or part diameter for turning in millimeters and click the CALCULATE button.

The program will calculate the CNC machine spindle speed in revolutions per minute.

 

   Sp =          

  D  =         

  

 Sn =
