We have 2 Hit-30M with live tooling that use Siemans 840D control.They have proven to be dependable workhorses.I would say that the live tooling on the Duplomatic turret has given us trouble occasionally but I believe that the Hit30-s does not have live tool.The Siemans control takes some getting used to if your going to use the conversational programing(We don't).
One of our lathes had the Z-axis ball screw rebuilt before we bought it.
The other blew an IGBT in the spindle drive for no apparent reason but I got a new drive off Flea-bay for $800.
Siemans stuff is readily available but service for either the lathe or electronics is very poor here in Phoenix.You pretty much have to do all your own troubleshooting.That said,I would not hesitate to purchase another if I had need.I would value each of our lathes at around $40K but I haven't priced anything lately so I could be full of it.
What kind of condition is the lathe? Pictures?
Feel free to contact me for any help I can give.(For what thats worth!)
