The machine comes from a single owner and was used in a single-shift operation in our own production facility. After the commissioning of a new manufacturing solution, the machine was decommissioned, the spindle was renewed/overhauled, and the machine underwent a comprehensive service. Since then, it has been in operational condition but is no longer used in production. The machine is in fully functional and ready-to-use condition. An inspection and a test run under power can be arranged at any time. Of particular note is the extensive overhaul of the boring/milling spindle in 2025, which brought a significant wear component of the machine back to like-new condition technically. Investment costs: 36.5 TEUR. Documents available.
