Deep-hole drilling

Easy-to-use cycles for deep-hole drilling are available in SINUMERIK Operate.
The tool drills at the programmed spindle speed and feedrate to the entered final drilling
depth.
Deep hole drilling is performed with a depth infeed of a maximum definable depth executed
several times, increasing gradually until the final drilling depth is reached.
For example, the drilling machine can be retracted after each infeed depth either to the
piloting depth + safety clearance for chip removal or by the length of the programmed
retraction path for chip breakage.
You can also choose between the following drilling strategies:
With or without predrilling
With or without pilot hole
Soft first cut yes/no
Chip breaking/removal
Chip breaking and swarf removal
1 cut - drill in one step to the end
depth
Swarf removal to the piloting depth /

Benefit
Generate drill holes with more than one feed to any positions
