4. Design and function

The machine is a universal lathe. It has been designed and manufactured for straight turning and facing round or

regularly formed three-, six- or twelve-square workpieces in metal, plastics or similar materials.

The hollow work spindle enables you to clamp longer workpieces with a diameter of up to 25 mm.

The speed is regulated by repositioning a V-belt on pulleys. With the equipment variant, it is possible to adjust the

speeds progressively within the corresponding speed ranges.

The existing leadscrew enables longitudinal feed and thread-cutting. It is also possible to use the machine for

drilling jobs with the help of an (optional) drill chuck clamped in the tailstock.
