Re: [CAD_CAM_EDM_DRO] Re: GEM-500PCN bedmill - CNC ready

Actually, that would translate to 79"/rev. Assuming (not a good thing to
do) the feed rate is related to spindle RPM and the spindle were turning at
max (6000) RPM the feed rate would be a PHENOMINAL 474,000 IPM!

I'd have to agree...there's got to be some errors in those specs! Do you
suppose what they really meant was 2mm/rev on X/Y and 1mm/rev on Z? Maybe
something got lost in translation....those things do happen.

They also quote a 1.5 HP, 2.2 KW spindle motor. In my book, 2.2 KW works
out to nearly 3HP. Don't see how that could be mistranslated tho'.
