Hello
I have a 3.5kw chinese spindle, that says 18000 rpm on it. My question is, is it better to run it on that given 18000 or is it better to go with 16000 just to save the motor. What do you guys think (or know)?

Spindle speed is determined by the tools used and the materials being cut not.

I use downcut two flute end mills, mainly cut plywood. I don't really play around with the spindle speed at all. I sometimes cut plexiglass aswell, when is it better to increase and when is it better to decrease RPM?
