Re: Looking for CNC Lathe With Manual Capabilities
It's pretty easy to convert a manual lathe to CNC, the real challenge is to convert and keep the manual capability, even harder to make it a quick changeover (under a minute). You have to use a ball screw on the cross slide, but it is possible to use the longitudinal rack & pinion for the Z axis rather than installing a ball screw. That way you don't disturb the lead screw and quick change gearbox to keep that manual operation. It took me almost a year to figure out the best way to approach that to eliminate the backlash.
I would look for a older Jet gear head Taiwan built lathe (1980s), that would be a good platform to start with. Then start adding bits & pieces as you can afford it. Nothing wrong with a PM lathe either if you want to buy new. Matt sells good equipment and has excellent customer service.
