3. Dwell time at drilling depth DTB.
4. The tool is retracted by retraction distance V2 for chipbreaking and drills up to the next
infeed depth with programmed feedrate F.
5. Step 4 is repeated until the final drilling depth Z1 is reached.
6. Dwell time at final drilling depth DT.
7. The tool retracts to the retraction plane at rapid traverse.
Approach/retraction during stock removal
1. The tool moves with G0 to safety clearance of the reference point.
2. The tool drills with the programmed spindle speed and feedrate F = F · FD1 [%] up to the 1st
infeed depth.
3. Dwell time at drilling depth DTB.
4. The tool retracts from the workpiece for the stock removal with rapid traverse to the safety
clearance.
5. Dwell time at starting point DTS.
6. Approach of the last drilling depth with G0, reduced by the clearance distance V3.
7. Drilling is then continued to the next drilling depth.
8. Steps 4 to 7 are repeated until the programmed final drilling depth Z1 is reached.
9. The tool retracts to the retraction plane at rapid traverse.
Deep-hole drilling at the entrance to the hole
The following versions are available for deep-hole drilling 2:
● Deep-hole drilling with/without predrilling
● Deep-hole drilling with pilot hole
Note
Predrilling or pilot hole mutually exclude one another.
Predrilling
For predrilling, the reduced feedrate (FA) is used up to the predrilling depth (ZA) and then the
drilling feedrate is used. For drilling with several infeed steps, the predrilling depth must be
between the reference point and the 1st drilling depth.
Through drilling
For a through-hole, starting from the remaining drilling depth (ZD), a reduced feedrate (FD) is
used.
