I'm looking at a Fadal VMC 4020HT. It's $9,500. They say it's fully functional and the spindle and axis' sound good. They'll do a ball bar test if requested. I know nothing about these machines. I run a Bridgeport knee that I converted to CNC about 15 years ago.
1. I guess I should ask is it worth it?
2. What should I ask or look for?
3. Are there any upgrades it needs such as something to interface it with a modern computer for uploading of G-Code? I'm just assuming since it's so old that it uses something obsolete.
4. Bonuses would be rigid tapping and 4th axis wired.
Any help would be appreciated. TIA
