Machining The following machining operations can be selected:
● 1 cut
The thread is drilled in one cut without interruption.
(not in the "with
compensating
● Chip breaking
chuck" mode)
The drill is retracted by the retraction amount V2 for chip breaking.
● Swarf removal
The drill is retracted from the workpiece for swarf removal.
