MACHINE FOR SURFACES OF PARTS ROTATION FINISH Russian patent published in 2020 - IPC B24B5/06 B24B5/36 B24B27/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used for finishing of surfaces of rotation of parts like rollers of roller bearings and other similar parts. Proposed machine comprises bed with lengthwise guides to move table, abrasive tool, abrasive tool fastening device arranged vertically to displace, device to secure and rotate machined part. Abrasive tool is made in the form of abrasive wheel on flexible binder and installed so that abrasive wheel rotation plane and processed part rotation plane are located mutually perpendicular, wherein device to straighten said wheel by preset profile of machined part surface. Bearing lever is installed on the table with the possibility of rotation at the specified angle in the forward or backward direction in the plane of rotation of the abrasive wheel. On bearing lever there is device for fixation and rotation of processed part.

EFFECT: wider technological capabilities of the machine, reduced roughness of the treated surface.
