When using these high RPM spindle motors on the router, I try to use single flute small diameter end mills. That allows a higher spindle RPM where the motor makes a bit of power without having a cut depth that is friction burning rather than cutting. Managing friction is very important when milling plastics, and the Onsrud O flute carbide bits do a good job, although they're expensive so do some slow air cuts when writing your own G code. I run the water cooled spindle motor between 9000 and 24000 RPM. Bogging it down with low RPM makes more heat than power. _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
