I recently acquired an older Nakamura Tome CNC lathe from 1981. I looked through the manuals and the only thing they mention about wiring is to have a power source with 3 phase 230 volt connections. I put the lathe in a spot where we used to have an old Vulcan CNC mill(gone before I started working here), and it has a fused disconnect from a 30 amp breaker that is set up with 10 gauge THHN stranded wire.
All of our HAAS mills, including our VF-8, are wired this same way.
Can I wire the lathe to the disconnect box using the same 10 gauge wiring? I read some other posts on the forum, and it seems like CNC lathes pull more amps than mills dues to the initial draw to spin up the chuck, but other than that there wasn't a lot of consensus on the wiring size.
Also, the main switch on the back of the cabinet is 100 amps, but I don't know if that factors into actual amps that the machine draws.
The breaker panel nearby used to support 3 older cnc mills, so I can probably get something going if I need to modify things.
