Insert the second interchangeable head
Insert the touch probe
Measure the interchangeable head with Cycle 452
Measure only the axes that have actually been changed (in this
example: only the A axis; the C axis is hidden with Q422)
The preset and the position of the calibration sphere must not be
changed during the complete process
All other interchangeable heads can be adjusted in the same way
The head change function can vary depending on the
individual machine tool. Refer to your machine manual.
