Function
The tool drills at the programmed spindle speed and feedrate to the entered final thread
depth.
You use this cycle to perform tapping with the compensating chuck:
● without encoder
● with encoder
Sequence
Tapping with compensating chuck without encoder
Position reached prior to cycle start:
The drilling position is the position in the two axes of the selected plane.
