FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used for finishing-cleaning and hardening of parts in free granulated medium. Machine comprises elastically installed on foundation with means for loading and unloading drum with drive, having end walls. Drum is made with surface along perimeter in form of alternating projections of trapezoidal shape and triangular cavities and with flat end walls of ellipsoidal shape, parallel to each other, arranged inclined at acute angle to horizontal axis of rotation of drum and with generatrices in form of alternating projections of trapezoidal shape and triangular cavities. Large axes of ellipses of said end walls are turned relative to each other at acute angle. Along the whole length of the drum there fixed is conic spring of elliptic shape in cross section with square cross section of turns, and along the entire length of the machine from the loading to unloading there fixed is spring of cylindrical shape with square cross section of turns.

EFFECT: enlarging technological capabilities of machine and increasing processing efficiency.
