You can access the "Manual tapping" function by pressing the softkey "Tapping" in the

drilling cycle overview.

Alternatively, you can select "Tapping" with <Cursor keys> and activate with the input key.

Parameter Description

Reference z0 Start position for the drill hole in the longitudinal axis

(absolute position of Z axis)

Drilling depth l Enter the thread length here. The tapping direction is always towards the chuck and cannot

be reversed. The choice of "left-hand or right-hand thread" depends on the direction of

rotation of the spindle and the thread tapping tool.

Lead s Enter the thread pitch here.

With compensating chuck /

Rigid tapping

Depending on the manufacturer, you can select as to whether the machining is carried-out

with or without compensating chuck.

Tapping operation

The machining sequence is as follows:

1. Starting from the current axis position, the tool is traversed to the cycle start point in the

longitudinal axis. This is calculated internally from the value for the "Reference z0"

parameter (taking into account the clearance distance).

2. The transverse axis is positioned to the center of rotation.

3. The controller then waits (at the cycle start point) for the next zero mark of the spindle

encoder in order to start the axis movement in the longitudinal axis (defined thread start

point).

4. When the thread length (end point) is reached, the spindle and longitudinal axis change

direction and withdraw the tapping tool from the drill hole again.

5. The longitudinal axis then stops at the cycle start point and the spindle changes direction

again. The spindle is now running in the direction in which it was originally started.
