Description
Thread lead in ...
The pitch is determined by the tool used.
MODULE: Used with endless screws, for example, which extend into a gear
•
wheel.
Turns/": Used with pipe threads, for example.
•
For values entered in turns/", enter the integer in front of the decimal point in
the first parameter field and the figures after the decimal point as a fraction in
the second and third field.

•
in/rev
•
Starting angle offset - (for rigid tapping only)
Spindle speed - (for rigid tapping only)
The following machining operations can be selected:
One cut
•
The thread is drilled in one cut without stopping
Chipbreaking
•
The drill is retracted by the retraction distance V2 for chipbreaking (not for
tapping with compensating chuck)
Stock removal
•
The drill is retracted from the workpiece for stock removal (not for tapping with
compensating chuck)
Maximum depth infeed - (for stock removal or chipbreaking only)
Retraction distance - (for chipbreaking only)
Manual
•
Retraction distance after each machining step (V2)
Automatic
•
Without retraction distance after each machining step
Retraction distance after each machining step – (for chipbreaking and manual
retraction only)
Distance by which the drill is retracted for chipbreaking.
V2 = automatic: The tool is retracted by one revolution.
Dwell time at final drilling depth in seconds
Spindle speed for retraction - for rigid tapping only
