  • Patent number: 10105822
    Abstract: A holding device, in particular a grinding disc, for a grinding member includes at least one support member that has at least one material opening configured for transverse transport of grinding dust to one side facing the grinding member in a plane parallel to a grinding surface. The holding device further includes at least one securing layer configured to secure the grinding member on the at least one support member. When decoupled from the grinding member, the at least one material opening is at least substantially open on a side facing the grinding member and on a side facing away from the grinding member is substantially delimited by the support member.

  • 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.

  • Publication number: 20180050437
    Abstract: A structural unit, in particular a grinding wheel has a hole pattern for sucking away swarf from a machining surface. The hole pattern has at least three recesses which are arranged essentially along a first spiral line. The hole pattern also has at least three further recesses which are arranged essentially along a second spiral line which intersects the first spiral line in a region of at least one recess.

  • Publication number: 20130344783
    Abstract: A circular grinding wheel has a center point and defines a multiplicity of extraction holes, which, in particular, are circular extraction holes. The center point of each extraction hole is arranged at the point of intersection of a radial line extending from the center point of the grinding wheel with a circle of holes that is arranged concentrically with respect to the center point and that has a radius. At least one of the radial lines is a single-hole radial line, on which the center point of only a single extraction hole is arranged. The center points of all the extraction holes that are arranged on a single-hole radial line lie substantially on a common single-hole circle having a radius. Each radial line comprises the center point of an extraction hole on at least one radius on which the two radial lines that are adjacent to this radial line in the circumferential direction have no center point of an extraction hole.
