Steady progress,  just flipped this on.  400a three phase.  The Okuma needs some big wires, 2/0 to the machine!

  • henryholstersThat's some serious copper.
  • genuinesaab@henryholsters Tell me about it.$$$$$. At least now the battery backups won't beep on tool changes. ;)
  • klevispriftiHope you have a big air compressor. We had to get a screw compressor for the Okuma and to run the whole shop. The two regular 100gal tank ones we had could not keep up it would alarm every two tool changes.
  • genuinesaab@klevisprifti pretty sure we do, it's a 15hp 3phase.
  • olsonkustomworksDamn those must use some current and cfm. My lancer takes 100a 3ph and it's ran with 4ga, and runs off my little 11cfm 40gal compressor. And I run the mycenter at the same time.
  • genuinesaab@olsonkustomworks ran Brother,VF2,VF1,SL10 plus compressor, cold saw, manual lathe and mill all off the (overloaded) 100a. But never blew the main. This one takes 150a breaker. Plus enough leftover for AC and a new lathe in a few years.
  • olsonkustomworksWe only have 175@ of service at the new shop. Old shop was 800. I gotta be careful when both machines are running not to turn the TIG up too high or it blows the main. Lol. 150a ain't no joke. Spindle spin up must pull a bunch.
  • klevisprifti@genuinesaab I would recommend wrapping the coolant pump with screen as the Okuma tank coolant screens let small chips go through and on the spindle head there is a check valve it will collect chips and coolant will stop flowing . It happened twice on ours and lost two very expensive tools from it. Other then that it is a beast you guys will like it.
  • cnccuttingedgeThat's like what comes out of the transformer on our Makino
  • focused_14Pulling that gauge of wire through conduit had to be my least favorite thing about relocating a machine shop with 7 machines.
