ABRADING TOOL FOR A ROTARY DRESSER
First Claim
1. A roller assembly for a rotary dresser comprising a plurality of discs, each disc provided with an abrasive, radially outer surface, 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 one or more discs has been subjected to a process of material removal whereby to form a pre-defined pattern of individual abrasive units.

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.

- 2. A roller assembly for a rotary dresser comprising at least one disc provided with an abrasive, radially outer surface which has been subjected to a process of material removal whereby to form a pre-defined pattern of individual abrasive units, the discs(s) secured in axial alignment with at least one roller portion having an arrangement of abrasive grains about its radially outer surface, the disc having a finer grained abrasive surface than the one or more roller portions.

16. A roller for a rotary dresser, the roller provided with an abrasive, radially outer surface onto which axial segments are defined wherein the radially outer surface of the roller has been subjected to a process of material removal whereby to form a pre-defined pattern of individual abrasive units on each defined axial segment and wherein the pre-defined pattern is different for different axially defined segments whereby to address different dressing needs and tool wear rates at different axial positions along the roller.
