Puko Mechanical Ring Stretcher 2.

The device is used for enlarging and calibrating rings. Magnification takes place in an expanding mandrel made of ground tool steel. Thanks to the installed scale and limiting pins, it is possible to automatically change the size of the ring up to the desired size, and thanks to 90 expansions on it, the inner part of the ring is optimally even without any additional thresholds or scratches.

The device is powered by a 220/230V motor with a power of 0.37 kW.
