Just wanted to send out a ‘heads up’ to possibly save someone else some grief.
I recently purchased a Nardini 14x40 lathe in pristine condition from a retiring machinist.
These suckers, by many accounts, are a great precision lathe. My glee, however, has turned into a bit of frustration, as I try to get the thing wired up and running.
I do not have 3 phase available in my shop, so I’m dependent on phase converters. It turns out that Nardini lathes do NOT work with static phase converters, according to Phase-A-Matic and another converter company. They have a funky Brazilian motor that draws greater than normal load at start up. A rotary converter is needed, which would normally be no big deal, as I already have a 5 HP rotary for my Bridgeport.
The icing on the cake is that the good folks at PhaseAMatic tell me that a 15 horse! converter is needed to run the Nardini’s 6.75 horse motor, due to peculiarities with that particular motor!
I’m not looking forward to buying another rotary at this point, along with the extra noise and power draw, but it doesn’t look like I have many options.
Moral of the story is, if you’re buying 3 phase machines that will be run on some type of phase converter, check with the converter manufacturer to be sure it’s a go. Apparently, Nardinis are the rascals of the converter industry…a little homework on my part would have saved some grief.
Anyone with any secret voodoo tricks on getting Nardini’s to run on static, I’d be forever grateful for your help! Or maybe a good, cheaper source for quality rotary converters other than MSC/Enco?
