I would check with the manufacturer of the CNC lathe. So many CNC machines are custom products that sometimes the manufacturer is the only one that can provide parts.
You can get parts through http://www.machinetools.net.tw/parts/e-catalog-420-597.htm They have online catalogs of parts.
Chances are if you search for CNC Lathe on ebay or Craigslist you'll be able to find out what you need. There are a variety of equipment available on these sites.
The two axises used on a CNC lathe are:X - CrossZ - Longitudinal
A cnc lathe can manufacture nearly anything cylindrical. Some even have attachments to do other types of work in the machine as well, for a virtually endless array of parts. Whatever you can imagine really, as long as it will fit in the machine.

2-Axis CNC machining refers to a CNC lathe which only needs two axises, X and Z, to perform its function.
It makes round things.

Harrison Lathe is a UK based company which manufactures comprehensive lathe machines. It sells Conventional (engine) Lathes. They also sell Manual or CNC Lathes.
The main difference is the following: On a CNC Lathe the material to be worked is held in a chuck and rotated around and the tools are clamped. These tools are then moved against the rotating material to cut into it. On a CNC Mill the tools are held in a chuck and rotated around and the material to be worked is clamped. These tools are then moved against the stationary material to cut into it.
