Excerpt from 14 Tips for Buying a Used CNC Lathe:
Inspections: Axes
All axes should move freely with smooth transitions and minimal oscillation after stopping. Listen for any unusual whine or buzz from the servo motors. Run a full stroke on each axis (in rapid mode, if available), listening for any indication of bad bearings or ball screws.
If the lathe has an open configuration, you can do a basic check of the angles between each axis using a hand held laser square. Depending on the cost of the machine and the type of work you will be doing on the lathe, you may wish to invest in advanced testing for accuracy, precision positioning, repeatability and backlash.
