Parameter Description Unit
D Maximum depth infeed - (only when used without compensating chuck, swarf removal
or chip breaking)
mm
Retraction Retraction distance - (for chip breaking only)
● Manual
Retraction distance after each machining step (V2)
● Automatic
The tool is retracted by one revolution.
V2 Retraction distance after each machining step – (only without compensating chuck, chip
breaking and manual retraction)
Distance by which the drill is retracted for chip breaking.
mm
DT (for ShopMill,
only in the "with
compensating
chuck without en‐
coder" mode)
Dwell time in seconds:
● without compensating chuck
– 1 cut: Dwell time at final drilling depth
– Chip breaking: Dwell time at drilling depth
– Swarf removal: Dwell time at the drilling depth and after retraction
● with compensating chuck
– with encoder: Dwell time after drilling
– without encoder: Dwell time at final drilling depth
