4.7 Drilling cycles
Deep-hole drilling, axial
Select drilling
Select deep-hole drilling, axial
The cycle produces a bore hole on the face 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. The drilling depth is reduced with
each subsequent pass by the reduction value, however, without
falling below the minimum drilling depth.
Cycle parameters
X, Z Starting point
C Spindle angle (C-axis position)
Z1 Start point drill (starting point of hole; default: drilling starts
from Z)
Z2 End point drill (end point of hole)
P 1st drilling depth (default: hole will be drilled in one pass)
IB Hole depth reduction value (default: 0)
JB Minimum hole depth (default: 1/10 of P)
B Retraction length (default: retract to starting point of hole)
E Dwell time for chip breaking at end of hole
(default:0)
D Retraction—retraction speed and infeed within the hole
(default: 0)
 0: Rapid traverse
 1: Feed rate
AB Drilling lengths (default: 0)
V Through drilling variants (default: 0)
 0: No feed rate reduction
 1: Feed rate reduction at the end of the hole
 2: Feed rate reduction at the beginning of the hole
 3: Feed rate reduction at the beginning and end of the
hole
