A lathe is a compliant structure, so a kinematic mount doesn't seem like it would be as effective as one might like. Then again, the small Chinese lathes have the lowest standards of construction of any of the Chinese machine tools. They don't take them seriously. Would be nice to be able to get a small lathe to use on a mill table, but those things are basically pointless. ------------------------------------------------------------------------------ Is your legacy SCM system holding you back?
