A method of manufacturing a rotary abrasive machining tool, the rotary abrasive machining tool including a hub and a plurality of abrasive segments mounted to the hub, the method including the steps of: mounting each abrasive segment on the hub; machining an abrading edge on each abrasive segment while the abrasive segment is mounted on the hub.

Abrasive machining

A rotary abrasive machining tool () is shown. The tool comprises a hub () having plurality of axially-oriented radial slots in the outer circumference thereof, and plurality of abrasive segments each of which is located in a respective slot in the hub and which form an abrading surface (). The abrasive segments comprise a tab for location in a slot in the hub, and an abrading edge defining a plurality of abrasive elements.

A roller assembly for a rotary dresser comprise a plurality of axial segments which may be in the form of discs, each disc provided with an abrasive, radially outer surface. The discs are secured in axial alignment, each in a preconfigured rotational orientation. The disc assembly has a centrally arranged aperture for receiving a rotor shaft. The abrasive surface of the assembly can be accurately presented as an array of uniformly shaped abrasive units in a predefined pattern.
