Condition: refurbished (used), Year of construction: 2026, functionality: fully functional, center height: 150 mm, total length: 620 mm, Mechanics: All wear parts of the machine are replaced, including the infeed spindle in the X-axis. All assemblies are restored to as-new condition. After the overhaul, the machine is comparable to a new machine. Geometry: The machine is completely dismantled down to the guides. Before the geometry of the individual tables and assemblies can be restored, both guides of the X and Z axes are scraped by hand and restored to as-new condition. After completion, the machine receives a measurement report in accordance with the manufacturer's specifications. Painting: Once the geometry of the machine has been restored, it is prepared for repainting. All housings, tables and the machine bed are stripped of old paint, cleaned and repainted. Hydraulics: The entire lubrication system, including the lubrication unit, is replaced. The hydraulic unit is also completely overhauled.
