RIGID TAPPING without a floating tap
holder (Cycle 207, DIN/ISO: G207)
Cycle run
The TNC cuts the thread without a floating tap holder in one or
more passes.
1 The TNC positions the tool in the tool axis at rapid traverse
FMAX to the entered set-up clearance above the workpiece
surface.
2 The tool drills to the total hole depth in one movement.
3 It then reverses the direction of spindle rotation again and the
tool is retracted to the setup clearance. If you have entered a
2nd set-up clearance the TNC will move the tool with FMAX
towards it.
4 The TNC stops the spindle turning at set-up clearance.
