I’m just learning how to use this CNC router. I for some silly reason thought to use regular end mills to cut out aluminum, this was a bad mistake. Typical end mills spin between 600 and 900 rpm. The average router spins at speeds over 25,000 rpm. DO NOT USE END MILLS! Use single fluted CNC router specialty bits. Amana Tool have a special line for aluminum, plastics and hard plastics. Single fluted bits make a HUGE difference! With the right bit, I am able to cut out 1/8 inch aluminum in one pass with no cooling.
