This is a list of the components which I have accumulated to convert a manual lathe to a CNC lathe. It is not quite complete, but close.
- Lead ball screw and cross slide ball screw. Both with nuts and end bearings. (no pic yet)
- The electronic components.
Finally in the electronics section, I will need a computer, loaded with Mach3 and Ezilathe. Surprisingly, it does not need to be a particularly powerful PC. And there are advantages in using an older operating system such as XPpro. I think there are a couple of those in the attic. If not, I should be able to pick one up for under $100.
3. Various structural items. Most of these will be 20mm thick x 200mm wide steel, cut to size and shaped and drilled. I will take pics of these as I make them. I was planning to have them water jet cut, but the shapes a fairly simple so I will cut and machine them myself as I go.
So, that is most of the items for the job. I have spent about $AUD1100 on the ball screws and nuts, about $AUD1500 on the electronics and electrics, and maybe another $AUD500 on pulleys, belts, steel, taper locks, fasteners etc. I will add it all up accurately at the completion. The lathe was cheap, bought sight unseen a few years ago. So all up, I should have a CNC lathe for under $AUD4000. And many pleasant hours of design and machining. And a great learning exercise. Stay tuned!
