Clamping the spindle

The "Clamp spindle" function must be set up by the machine manufacturer.
Note for selecting the clamp spindle function under ShopTurn
The machine manufacturer also specifies whether ShopTurn will clamp the spindle
automatically if this would facilitate machining, or if you can decide the types of machining for
which the spindle should be clamped.
If you are to decide the types of machining for which the spindle is to be clamped, the
following applies:
You should note that when machining in the end face/end face C and peripheral
surface/peripheral surface C planes, clamping only remains active for contour milling and
drilling operations. On the other hand, when machining in the end face Y/end face B and
peripheral surface Y planes, clamping is modal, i.e. it remains active until the machining
plane is changed.
