  • Rough grinding wheel comprising a core
    Patent number: 11235437
    Abstract: A rough grinding wheel for processing material surfaces includes a wheel-shaped base body having a central recess penetrated by an axis of rotation for direct or indirect connection to a drive shaft of a tool. The rough grinding wheel has a stabilizing core stabilizing the rough grinding wheel. The stabilizing core is associated with at least one abrasive layer circumferentially adjacent to the central recess. The stabilizing core has a higher strength than the at least one abrasive layer.

  • Multilayer abrasive particle
    Patent number: 10081747
    Abstract: The invention relates to a multilayer abrasive particle (01) having a layer structure of stacked layers (02), each of the layers (02) being formed parallel to a plane (E). The exposed surfaces (04) of the layers (02) not covered by another layer and/or the edges (08) connecting the exposed surfaces (04) extend at least partially convexly or concavely in relation to the plane (E) and/or to a plane (E2) that is perpendicular thereto and comprises the direction (03) of the layer thickness.

  • Method for producing multilayer abrasive particles
    Patent number: 9663693
    Abstract: A method for producing multilayer abrasive particles (12) is proposed, comprising the following method steps: providing a substrate support (01) and at least one dispersion of an abrasive particle precursor (05); repeatedly positioning at least one grid structure (02) above the substrate support (01), covering areas (03) being defined by at least partially covered grid meshes (11) and printing areas (04) being defined by open grid meshes (11); applying the at least one dispersion of an abrasive particle precursor (05) onto the grid structure (02), a contact being formed between the grid structure (02) and the substrate support (01) or layers (08) arranged on the substrate support (01), and a dispersion layer (07) being deposited in the printing areas (04) on the substrate support (01) or on the layers (08) previously arranged thereon when the contact is lifted, and subsequently drying each deposited dispersion layer (07) to form a layer (08).
