Feeds and Speeds

(Anthony Bolgar) #1

Does anyone have some good resources for speeds and feeds for different materials and bits? I am especially looking for info on milling 6041 aluminum with my Sphinx leadscrew driven router. It has a 1.5kW spindle on it, and has heavy duty high torque steppers (450oz-in) so I am pretty sure I can do some simple plate making with it.

I have a cheat sheet I made. Figure out your feed per tooth (0.001-0.0015” is a safe start). Look at the tabs for imperial vs metric, and a few resources for materials and specific cutters.

Surface feet per minute is important on certain materials, like aluminum.

Thanks, that helps a lot. Should help lower the number of broken bits as I test my new machine out.
