METHOD OF COMBINED PROCESSING BY GRINDING AND SURFACE PLASTIC DEFORMATION Russian patent published in 2008 - IPC B24B39/04 

FIELD: mechanical engineering.

SUBSTANCE: workpiece is imparted rotary and spring tool is imparted longitudinal feed. Spring tool is used containing the case with bores accommodating freely running rolling bearings and working abrasive-diamond-containing and deforming elements. Working abrasive-diamond-containing and deforming elements are made in the form of ellipse coils curled up to make a ring. The external working surface of the abrasive-diamond containing and deforming elements has deforming sites and abrasive-diamond sites opposite to the latter. The former is made so that to envelope the workipiece and to make an interference fit with the latter. Here, the aforesaid spring is arranged in the case freely and can be unscrewed to allows the workpiece superficial plastic deformation or grinding.

EFFECT: extended process performances, higher efficiency and lower costs.
