Hey guys, Ive been starving for some more rpms. I typically use 1/4" endmills for my little aluminum projects, but 2400rpms isn't enough.
I've read the stock bearings can handle 3800 if you gear it? That may be the easiest option.
However I am curious about two others, can any one give me any info on using the stock motor and speed controller for a new high speed spindle set up. If I built my own milling head and spindle, then geared the stock motor to drive a spindle at 6000rpm for example, would and could the speed controller/motor handle that?
Second idea, variable speed 1/4-1/2" router. While I see most sit around 8-16k rpms, can any one comment on the life span of a router being used to machine aluminum?
I should mention I'm not really in the market for engraving, I just want to drive my 1/8-1/4 endmills a little closer to their proper speeds in aluminum.
Thank you so much.
