Setting up a counterspindle

Function
If your turning machine has a counterspindle, you can machine workpieces using turning,
drilling and milling functions on the front and rear faces without reclamping the workpiece
manually.
Before machining the rear face, the counterspindle must grip the workpiece, pull it out of the
main spindle, and position it at the new machining position.
