Deep-hole drilling, axial/radial
Call the drilling menu.
Select the "Deep-hole drilling, axial" cycle.
Select the "Deep-hole drilling, radial" cycle.
The cycle produces a bore hole on the face / lateral surface in several
passes. After each pass, the drill retracts and, after a dwell time,
advances again to the first pecking depth, minus the safety clearance.
You define the first pass with "1st hole depth P." MANUALplus then
automatically reduces the drilling depth with each subsequent pass by
the "reducing value IB," however, without falling below the "minimum
drilling depth JB."
