Our client, [HR Werkzeugmaschinen GmbH](https://www.hr-werkzeugmaschinen.de/), located in Kakenstorf near Hamburg, specializes in the general overhaul of machine tools and equipment. To save an old, technically and structurally aging heavy-duty lathe through re-engineering, they relied on a ZIMM Z-Series screw jack systems.

Using such a gearbox as a pre-tensioner for the jaw chuck of a large machine tool is definitely something unusual and also required some courage. This innovative decision was jointly taken following a personal visit by our sales representative for northern Germany, Frank Achenbach, and a productive discussion about the project.

Finally, a Z-1000-SL worm gear screw jack with trapezoidal thread for a stroke of 200 mm was installed in a lathe. The gearbox has now been running excellently for around six years and meets all requirements of the end customer based in Siegen.
