How Automatic calibration for the flip head rotation axis works

► The flip rotation axis is referenced.

► The flip Z axis is moved down by 3mm. In that case, the Z position defined by the holding cyl-

inder will be used as the home position of the Z axis because the Z axis is possibly not calib-

rated at this point.

Fig.538:

► The flip rotation axis is moved until there is a time-out by touching the Z axis actuator with the

bearing of one segment. This position of the rotation axis saved.

Fig.539:

► After that, the rotation axis moves in the opposite direction, until the Z axis actuator is touched

by the bearing of the other segment. This position is also saved.

► From these two positions of the flip rotation axis, the average value is calculated and thus the

home position of flip rotation is defined.

15.3.2.3 Calibration – flip head Z axis

NO RISK OF SERIOUS INJURIES

► Setup mode not activated!

Machine covers are closed!

This calibration detects the correct zero point of the flip head Z axis with respect to the raceway of

the flip head rotation axis.

After the calibration, the actuator of the flip head Z axis is exactly positioned with respect to the

raceway, so that there is no effect on the Z axis during the rotation and there is finally no deviation

of the ball bearing!

Fig.540:

► Choose Service Calibration Z axis on the right menu bar.

Fig.541:

► Choose Start Calibration.

ð The complete automatic calibration of the Z axis starts.

► During the automatic calibration, the status Execute is active.

► After successful automatic calibration of the Z axis, the status changes to Ready.

► The calibrated Z axis zero point correction value is shown at Home position of Z axis (µm).

How Automatic calibration for the flip head Z axis works

●

The Z axis holding cylinder is used as the start home position for the Z axis.

●

The flip rotation axis is moved to the home position.

●

The flip head rotation axis is rotated to the right by a defined value.

Fig.543:

●

The Z axis is moved down until the the time-out when the bearing touches a segment.

●

This Z value is saved.
