FIELD: metallurgy.
SUBSTANCE: device contains case, burnishing tool, located with tension in collet in the form of slotted boss with hole, parts of which are connected by resilient radiuses with hoop, and drive of burnishing tool with thruster. Burnishing tool is implemented with inverse cone. Hole of chuck collet hub is implemented in the form of truncated cone. Burnishing tool is installed with back taper into hole of collet hub with formation of self-braking connection. Collet is rigidly fixed on bottom part of movable axially bush, mounted in top part of case.
EFFECT: there is reduced expenditure of energy and device reliability is increased.
