Tormach does exactly that. They sell a 7x lathe fitted out as a 4th axis to set on their CNC mill's table. It's an interesting idea, gives the ability to do regular turning work on the lathe and 4 axis CNC work on the same piece without having to take it off the lathe. Bolting the lathe solidly to the mill table would help its rigidity, same as bolting any 7x to a large hunk of U channel or rectangular tube. I might look into that as a 4th axis after I get my knee mill going. Crap, now I'm thinking I shouldn't have sold both of those lathes, but that's where I got the money to buy a junker 1967 South Bend 9" model A I restored then sold for $2K. --- This email is free from viruses and malware because avast!
