FIELD: mechanics.

SUBSTANCE: device comprises two disks with central holes, one of which has L-shaped holder, and the other is rigidly fixed at the end of the first disk, and deforming elements that are movably installed between disks. Deforming elements are arranged in the form of steel helical cylindrical spring turns from circular wire installed at two yokes that embrace processed billet and are installed on two levers. Levers are hingedly connected to each other with the help of axis installed on one end of levers and are movably installed horizontal between disks one above the other. Lower lever middle rests on external ring of bearing installed between disks and sitting on axis.
