RE: [CAD_CAM_EDM_DRO] cnc lathe project

I agree with Stan about buying a lathe.
Choice of chuck interface is not important. Camlock and small do not usually
go together.
Chuck interface converters other than backplates for plain back chucks do
not exist.

Have you considered collets e.g. 5C instead of a 6 jaw chuck

Assuming a 6 jaw chuck is essential.

Research available affordable 6 jaw chucks

Research available affordable lathes.

Select a suitable pair and buy

Treat the lathe as a kit of parts. It will be cheaper than buying the parts
individually.
