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.

A detailed description of MD52006 is provided in Chapter "Activating turning/milling/drilling/
grinding technologies (Page 75)".
Traversing direction
In order that the user interface and cycles know in which direction the spindles and rotary axes
rotate, the following settings must be made.
You set the direction of rotation of an NC rotary axis via MD32100 $MA_AX_MOTION_DIR.
