ABRASIVE WHEEL FOR MACHINING SHAFTS OF HYPERBOLIC PROFILE CONNECTION AND BROACHING TOOL WITH HYPERBOLIC PROFILE Russian patent published in 2010 - IPC B24D5/02 B24B19/08 

FIELD: machine building.

SUBSTANCE: abrasive wheel consists of abrasive particles and features work surface representing hyperboloid of one sheet with its rectilinear generating lines arranged at an angle to its rotational axis. Required profile of machined part is produced in arranging abrasive wheel at angle to feed direction. Abrasive wheel features density, in direction from its edges to center, that varies in reverse proportion to abrasive wheel radius for its given section and meeting the condition: R_i ρ_i = const, where R_i is current radius of abrasive wheel during its wear; ρ_i is current density of abrasive wheel with radius R_i.

EFFECT: higher accuracy of ground surfaces and reduced costs of machining.
