Drilling centric

Function
Using the "Drill centric" cycle, you can perform drilling operations at the center of a face
surface.
You can choose between chip breaking during drilling or retraction from the workpiece for
swarf removal. During machining, either the main spindle or counterspindle rotates. You can
use a drill, rotary drill or milling cutter as the tool.
The tool is moved with rapid traverse to the programmed position, allowing for the return
plane and safety clearance.
Note
Working with rotating tool spindle
For example, if you want to drill very deep holes, you can also employ a rotating tool spindle.
First specify the required tool and tool spindle speed under "Straight/Circle" → "Tool". Then
program the "Drill centered" function.
Note
Stop tool spindle
If, during "Center drilling", the tool spindle does not rotate despite having been previously
activated, then program the "M5" G code command before "Center drilling" in order to stop
the tool spindle.
Input simple
For simple machining operations, you have the option to reduce the wide variety of
parameters to the most important parameters using the "Input" selection field. In this "Input
simple" mode, the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
