Operations
The following steps are available to program the operations:
● Gripping: Gripping the workpiece with the counter-spindle or main spindle (possibly with
limit stop)
● Withdrawing: Withdrawing a workpiece with the counter-spindle from the main spindle or
with the main spindle from the counter-spindle
● Counter-spindle machining side: Traverse workpiece with the counter-spindle or main
spindle to a new machining position; select work offset for the machining side
● Complete transfer: Gripping, withdrawing (possibly with cutting-off) and machining side
● Main spindle machining side: Work offset for machining the next front face (for bars)
If you start to execute a program containing a counter-spindle machining operation, the counter-
spindle is first retracted to the return position defined in a machine data element.
Teaching in the parking position and angle offset
Teaching the park position is possible only if you have selected the machine coordinate system
(MCS).

Machine manufacturer
Please refer to the machine manufacturer's specifications.
1. Manually rotate the counter-spindle chuck to the desired position, and
move the tool to the desired position.
2. Press the "Various" and "Counter-spindle" softkeys.
3. Select the "Gripping" or "Complete transfer" programming step.
4. Select the "MCS" tool under the park position.
5. Press the "Teach park pos." softkey.
The actual tool park position is saved.
6. Press the "Teach angl. offset" softkey.
The actual angular difference between the main and counter-spindles will
