ECOTUBE honing machine for stroke lengths up to 10000 mm

The ECOTUBE is the standard machine series for diameters up to 500 mm (extendable as an option to 800 mm). The main application areas are hydraulic cylinders, pipes and extruders. The maximum honing length amounts to 10000 mm. As with the HM series the expansion can be made electromechanically or hydraulically. A rotary drive for the workpiece is also available for this series.
