Machine for finishing, grinding and hardening processing of low rigidity parts Russian patent published in 2021 - IPC B24B31/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used for grinding, polishing and hardening the surface layer of parts in a freely granular abrasive medium. The machine contains a drum mounted on a frame with a rotation drive and devices for loading and unloading parts. The drum is made in the form of a helical rotor made of at least four rectangular strips, alternately connected to each other, rolled in a vertical plane in the longitudinal direction and bent on a cylindrical mandrel along helical lines in the transverse direction. The strips are connected to form along the perimeter inside or outside the helical rotor, helical lines and curved helical surfaces of the second and higher degree of curvature of one direction in the form of helical grooves of a convex or concave shape of one direction with the centers of curvature outside or inside the helical surface.

EFFECT: expanded technological capabilities, improves parts processing quality.
