Abstract
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.

A roller assembly for a rotary dresser comprising a plurality of discs, each disc provided with a radially outer surface that is abrasive, the plurality of discs secured in axial alignment, each in a preconfigured rotational orientation and a centrally arranged aperture for receiving a rotor shaft and wherein the radially outer surface of one or more discs has been subjected to a process of material removal whereby to form a pre-defined pattern of individual abrasive units, wherein
- the plurality of discs comprising discs having different outer diameters, and
- the plurality of discs are arranged with discs having outer diameters that are the largest positioned in a middle of the roller assembly and are arranged such that diameters of subsequent discs are smaller from the middle of the roller assembly to each axial end of the roller assembly.
A roller assembly for a rotary dresser comprising a plurality of discs, each disc provided with a radially outer surface that is abrasive, the discs secured in axial alignment, each in a preconfigured rotational orientation and a centrally arranged aperture for receiving a rotor shaft and wherein the radially outer surface of two or more discs has been subjected to a process of material removal whereby to form a pre-defined pattern of individual abrasive units, wherein
- each of the individual abrasive units, which are located on a first disc of the plurality of discs, include a first geometry, and
- each of the individual abrasive units, which are located on a second disc of the plurality of discs, include a second geometry that is different than the first geometry.
