DEVICE FOR FINISHING AND HARDENING PROCESSING Russian patent published in 2016 - IPC B24B31/02 B24B31/73 

FIELD: machine building.

SUBSTANCE: invention can be used for grinding, planishing and hardening of surface layer of parts. Device comprises a drum made in the form of a spiral tunnel, fixed on the platform and elastically installed at the bed. Drum is rigidly fixed on the platform with a horizontally mounted dipole, made with multithread screw surface along the perimeter and folded along a spiral axis of symmetry around a central rectilinear drum axis so that spiral grooves in the form of wavelike pockets are formed inside. Drum consists of rhomb-shaped strips, where trapezoids are installed which lateral sides are located on lateral sides of the strip, top and bottom bases of trapezoids are arranged at an acute angle to strip axis of symmetry and are crease edges. Sections are interconnected by lateral sides of trapezoids.

EFFECT: expanded performances, higher intensity of processing.
