Condition description:
About half a year ago, the cross roller bearing on the Carnaghi was replaced.
All Siemens components in the control cabinet were also completely renewed at the end of 2023.
Furthermore, the machine is equipped with a measuring probe for tool measurement and an external Renishaw measuring probe for workpiece measurement.

A special feature of the machine is an additional measuring probe on the Z-axis (Z1-axis).
This provides a benefit in accuracy and time as the tool does not need to be removed for measurement. However, this probe is currently deactivated and should be overhauled before recommissioning.
In addition, the machine is fitted with a Rotomors six-jaw compensation chuck with centrifugal force compensation, which was completely overhauled in 2020/21.
