When I said 1 mill I ment for every thing to actually get you into production. things like install, training, software, CMM and etc.
lets also not forget that most of these machines require lots of air, its often about 10 cfm at 100 psi. Thats alot of air and must be 100% duty cycle. Not a motor rated for 100% duty cycle, but the compressor rated for 100% duty cycle. That pretty much means a rotary with atleast 5 hp per machine. does not sound like much, but its about 5k to start. it wil most likly be 460V 3p and around 7 amps, thats like 4500 watts. Thats about $6k a year in just power if you pay $.15/kwh.
Granted thats a drop in the bucket for these operations, but every watt of power you use costs you. I know from exp that power is the largest cost for machine operations.
M58 tom would be able to answer that Q for you. I'd guess 30-60 tools in each machine, I'd guess atleast 10 get swaped out every shift.
