Title: first cnc
Post by: tom osselton on August 12, 2017, 04:05:46 PM
Well I've been talking about getting a cnc machine for sometime now and my son found this one at his work it is unpluged but works and comes with the transformer and chip conveyor as well as a collet chuck I'm not sure about collets though. The guy who fixes their machines says it is in good condition / acurate, it was sold as a employee deal for $5000.00 so here we go jumping in with both feet!  :D
We just got the riggers quote $1850.00 to move it and set it up or whatever they do, then its just a matter of figuring out how to run it I've been going over the manuals but a cnc for monkey's book wouldn't hurt!

Well it gets delivered tomorow around 10 am, then we shall see what power it needs they told my son 220 he's thinking single phase to the transformer I'm thinking 3 phase if so we will need a converter. What would be a good choice in that respect balanced for cnc and we will be adding a mill shortly too. Heres the plate on the transformer.

Well that plate certainly implies 3 phase.

If I'm reading that name-plate correctly, you've got yourself a 30KVA 3 phase 480 volt primary to 240 volt auto transformer.  At least it looks like it says 30KVA.  According to my books you're looking at full load amperages of 36.1 in the 480 side and 72.2 on the secondary side.  That's kind of on the big side - but not huge.  What's that thing got, about a 20HP motor on the spindle?

Well it has landed but had to come down the alley on the forklift
Thats my son in the t shirt.
We cleaned any remaining chips and coolant tank then installed the conveyor.
We also were given a few soft jaws!
The motor says it is 29.5 hp at 57 amps and we would like to get a mill with about  7.5 hp so what wil I need for power a 40hp converter?
