Condition Description:
Pedpfxszaa T Ne Adzspt
About half a year ago, the cross roller bearing of the Carnaghi was replaced.
Additionally, the Siemens components in the control cabinet were completely renewed at the end of 2023.
Furthermore, the machine is equipped with a probe for tool measurement and an external Renishaw probe for workpiece measurement.
As a special feature, the machine also has a probe mounted on the Z-axis (Z1-axis).
This provides a gain in accuracy and time, since the tool does not need to be removed for measurement.
However, this is currently deactivated and should be overhauled upon recommissioning.
The machine also has a Rotomors six-jaw compensating chuck with centrifugal force compensation, which was completely overhauled in 2020/21.
