5.2 Turning cycles in CYCLE mode
You can perform deep hole drilling and thread drilling under the
"Drilling center" function.
Deep hole drilling
The workpiece rotates at the programmed spindle speed. The tool
drills in the longitudinal axis at the programmed feedrate until the
specified final drilling depth is reached.
The deep hole is drilled by repeated, stepwise depth infeeds (depth
value programmable) until the final drilling depth is reached.
As an option, the drill can be retracted after every infeed depth to the
reference plane for swarf removal or by a distance which can be
entered for chipbreaking.
Sequence of operations
CYCLE mode is selected.
