DEVICE FOR GRIND-ROLLING Russian patent published in 2008 - IPC B24B39/04 

FIELD: machine building.

SUBSTANCE: device consists of the housing and working abrasive diamond-containing elements aimed to process the rough workpiece with tension and cylindrical spiral spring with deforming elements. Cylindrical spiral spring is installed by means of tensioning equipment which is used to create forces providing a static load. Housing is equipped with brackets. Abrasive diamond-containing elements are made in the form of coils of spring rolled up to a ring with the abrasive layer on the inner surface. The coiled spring rolled up to a ring is installed with ability to cover the rough workpiece to be processed and to rotate forced by a gear-wheel from the individual electric motor. Inner diameter of the coiled spring rolled up to a ring is less than the diameter of workpiece to be processed by a double-tension value in order to ensure a radial feed of spring coils. Cylindrical spiral spring with deforming elements is hinge-jointed at the housing brackets with ability to rotate relative to its longitudinal axis and to cover the rough workpiece to be processed.

EFFECT: expansion of process abilities; reduction of device cost price; simplification of device design.
