Machining with movable counterspindle

If your lathe has a counter-spindle, you can machine workpieces using turning, drilling and
milling functions on the front and rear faces without reclamping the workpiece manually.
You have the possibility to start the machining in the main spindle or in the counter-spindle.
Prior to machining the associated front or rear side, the workpiece is gripped by the counter-
spindle or the main spindle, withdrawn from the main spindle or counter-spindle and travels to
the new machining position. You can program these operations with the "Counter-spindle"
function.
