  • Shaped ceramic abrasive particle and method for producing a shaped ceramic abrasive particle
    Patent number: 11697752
    Abstract: A shaped ceramic abrasive particle, in particular on the basis of alpha-Al2O3, includes at least three faces, at least two faces of which form a common vertex on which at least one corner common to the three faces lies. The abrasive particle has at least one structural weakening element. The disclosure also relates to an abrasive article including the abrasive particles, and a method for producing the abrasive particles.
    Type: Grant
    Filed: June 5, 2018
    Date of Patent: July 11, 2023
    Assignee: Robert Bosch GmbH
    Inventors: Jiri Misak, Moritz Oldenkotte, Stefan Fuenfschilling

  • Abrasive means
    Patent number: 9969057
    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.
