Abstract: A grinding tool for grinding an engine includes a main body with a central coupling region for connecting to a rotary drive of a grinding machine, the main body having a substantially rotationally symmetrical configuration with respect to an axis of rotation. The grinding tool also includes a grinding layer on the main body that extends over an outer circular ring zone of the main body, at least one feed for a cooling fluid, and a substantially circular cover plate arranged substantially normal to the axis of rotation and forming an axial gap on the main body. The axial gap is in fluid communication with the feed and the grinding layer so that a cooling fluid fed by the feed can be passed via the axial gap to the grinding layer.

Abstract: A grinding tool for machining an inside surface of a cylinder bore in a workpiece, the grinding tool having an axis of rotation, a grinding region which is cylindrical with respect to the axis of rotation and a conical grinding region axially adjoining the cylindrical grinding region. A diameter of the conical grinding region increases starting from the cylindrical grinding region in an axial direction with respect to a diameter of the cylindrical grinding region.
