Embodiment Construction

[0378] A first embodiment of an abrasive grain 10 according to the invention is shown in FIGS. Ala to le. Figure Ala here shows a perspective view; Figure Alb shows a front view; Figure Alc shows a side view; Figure Ald shows a top view. Figure Ale shows a side view of an abrasive grain 10 , wherein the abrasive grain 10 is disposed on a substrate 20 . Abrasive grain 10 has an almost square plan, comprising four corners 1 to 4 and four edges 4 to 8 connecting said corners 1 to 4 . The edges 5 to 8 are here designed straight, wherein curved edges are also conceivable. Starting from a flat square, however, the two opposite edges 2 , 4 are displaced upwards from the plane and the other two likewise opposite corners 1 , 3 are displaced downwards from the plane. Abrasive grain 10 thus has only two faces 11 , 12 . In this case, the two surfaces 11 , 12 are identical in the exemplary embodiment shown, ie only form the top or bottom of a single surface. Alternatively, it is also c...

Abstract

The invention relates to an abrasive particle (10) with at most three surfaces (11, 12, 13), wherein the abrasive particle (10) contains at least one edge (5, 6, 7, 8) which has a corner (1, 2, 3, 4) at at least one end. The abrasive particle (10) can contain a ceramic material, particularly polycrystalline alpha-Al2O3. Abrasive particles (10) as a whole, methods for producing abrasive particles (10), moulds, abrasive articles, methods for producing abrasive articles and methods for abrading a surface are also disclosed.

Description

technical field [0001] The invention relates to an abrasive grain having a defined shape, an abrasive grain population, a method for producing an abrasive grain, a casting mold, an abrasive tool with abrasive grains, a method for producing an abrasive tool, and a method for grinding a surface with an abrasive tool Methods. Background technique [0002] Abrasive grains, in particular ceramic abrasive grains, of defined shape and size have long been known. [0003] Document US 5,201,916 also discloses flat abrasive grains having, for example, a triangular, rectangular or circular shape. These abrasive grains are manufactured from a dispersant containing particles convertible to alpha-alumina and containing a liquid with a volatile component. The dispersion is cast into a mold having a flat base and a groove whose shape is complementary to the desired shape of the abrasive grain. Next, a part of the volatile constituents is removed, resulting in a semi-finished product with ...
