Deep-hole drilling 2 (CYCLE830)

Function
The cycle "Deep-hole drilling 2" covers the complete functionality of "Deep-hole drilling 1".
in addition, the cycle provides the following functions:
● Predrilling with reduced feedrate
● Taking into account a pilot hole
●
● Drilling to the final depth in one cut
● Through drilling with reduced feedrate
● Control for switching-in and switching-out the coolant
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".
Approach/retraction during chipbreaking
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.
