Z1 Drilling depth (abs) or drilling depth in relation to Z0 (inc)
DT
● Dwell time at final drilling depth in seconds
● Dwell time at final drilling depth in revolutions
SPOS Spindle stop position
Lift mode
● Do not lift off contour
The cutting edge is not fully retracted, but traverses back to the safety clearance in
rapid traverse.
● Lift
The cutting edge is retracted from the hole edge and then moved back to the retraction
plane.
DX (only G Code) Retraction distance in the X direction (incremental) - (for lift-off only)

Deep-hole drilling 1 (CYCLE83)

Function
With the "Deep-hole drilling 1" cycle, the tool is inserted in the workpiece with the programmed
spindle speed and feedrate in several infeed steps until the depth Z1 is reached. The following
can be specified:
● Number of infeed steps constant or decreasing (via programmable degression factor)
● Chip breaking without lifting or swarf removal with tool retraction
● Feedrate factor the 1st infeed to reduce the feedrate or increase the feedrate (e.g. if a hole
has already be predrilled)
