FINISHING MACHINE Russian patent published in 2019 - IPC B24B31/02 B24B31/06 

FIELD: technological processes.

SUBSTANCE: invention relates to the finishing-grinding treatment of parts in a free granular medium and can be used in mechanical engineering. Machine contains a hollow container rigidly mounted on the platform with a vibrator, made in the form of a hollow spiral tunnel, rolled up around its central straight axis and having helical grooves inside at an angle to its spiral axis in the form of curved pockets. Container consists of sections in the form of rings of the same shape and size, rolled from identical diamond-shaped strips, on which trapezoidal elements are placed, their upper and lower bases are at an acute angle to the symmetry axis of the diamond-shaped band and are the fold lines. Container sections are connected to each other by the lateral sides of the trapezoidal elements.

EFFECT: as a result, the technological capabilities of the machine are expanded and the intensity of machining of parts increases.
