Abstract

An abrasive member includes an abrasive member base and a plurality of abrasive particles applied to the abrasive member base. At least a large proportion of the abrasive particles form an abrasive edge unit with an abrasive edge inclined at an angle between 0° and 90° relative to a defined working direction.

First claim

1 . An abrasive means member, comprising:
an abrasive member backing; and a plurality of abrasive particles applied to the abrasive member backing, wherein at least a large proportion of the abrasive particles form at least one abrasive edge unit having an abrasive edge inclined at an angle between 0° and 90° relative to a defined machining direction.

2 . The abrasive member as claimed in claim 1 , wherein at least a large proportion of the abrasive particles form at least one abrasive edge unit having an abrasive edge inclined at a defined angle between 0° and 90° relative to the defined machining direction.

3 . The abrasive member as claimed in claim 1 , wherein the at least one abrasive edge unit is configured as a row of abrasive particles arranged at least substantially adjacently.

4 . The abrasive member as claimed in claim 1 , wherein the abrasive particles are purposefully placed.

5 . The abrasive member as claimed in claim 1 , wherein the abrasive member backing is configured as a cylindrical roller.

6 . The abrasive member as claimed in claim 1 , wherein the abrasive particles have a surface contour described at least substantially by a convex envelope.

7 . The abrasive member as claimed in claim 1 , wherein the abrasive particles have a ratio between a height of the abrasive particles and a diameter of a base area having a value between 0.3 and 1.2.

8 . The abrasive member as claimed in claim 1 , wherein the abrasive particles have at least substantially a pyramidal basic shape.

9 . The abrasive member as claimed in claim 1 , wherein the abrasive particles comprise at least one partially prismatically configured sub-element.

10 . The abrasive member as claimed in claim 1 , wherein the abrasive particles have a hexagonal base area.

11 . The abrasive member as claimed in claim 1 , wherein the abrasive particles have a quadrangular base area.

12 . The abrasive member as claimed in claim 1 , wherein the abrasive particles have an oval base area.

13 . The abrasive member as claimed in claim 1 , wherein the abrasive particles have at least one setback surface region that is configured at least partially as a groove.

14 . An abrasive particle for an abrasive member, the abrasive particle configured as one of a plurality of abrasive particles applied to an abrasive member backing,
wherein at least a large proportion of the abrasive particles form at least one abrasive edge unit having an abrasive edge inclined at an angle between 0° and 90° relative to a defined machining direction.
