  • Patent number: 10086491
    Abstract: A honing tool for working several separate bores that are arranged coaxially in series and have different diameters. The honing tool includes several cutting bar groups arranged coaxially in series, wherein a diameter of a cutting bar group of the several cutting bar groups, which diameter is formed by radially extendable cutting bars, differs from a corresponding diameter of at least one other cutting bar group of the several cutting bar groups. A centering bar group is arranged in an axial direction to a free end of the honing tool adjacent at least one cutting bar group; or a guide bar group is arranged directly adjacent opposite the free end of the honing tool adjacent the at least one cutting bar group, or both the centering bar group and the guide bar group are arranged accordingly.

  • Patent number: 10040158
    Abstract: A dressing device for dressing honing stones is provided with a base body and a mounting device for mounting the dressing device in a grinding machine. The base body has at least one honing stone receptacle that is a pocket. Honing stones are inserted and secured in the honing stone receptacles and the abrasive coating of the honing stones are ground by the grinding machine. A set of honing stones that is required for furnishing a honing tool can be dressed by one mounting action in the dressing device and can be inserted into the honing tool so as to be positioned exactly at the same radial position without requiring additional machining.

  • Publication number: 20140113535
    Abstract: A honing tool for machining cylindrical bores has a tool body provided with a guide bore and a feed rod disposed in the guide bore. The tool body has a honing stone receptacle extending from the guide bore in a radial direction of the tool body outwardly through the tool body. A honing stone is arranged in the honing stone receptacle. A pin is disposed in the honing stone and projects laterally from the honing stone. An elongate spring is disposed in the tool body parallel to the honing stone, wherein the elongate spring element has a first end section, a central section, and a second end section opposite the first end section. The central section is guided across the pin and the first end section is secured in the radial direction in the tool body.

  • Patent number: 8292695
    Abstract: The invention relates to a machine for creating non-cylindrical bore surfaces having a machine spindle (5), to which a machining tool (2-06, 3-04) can be connected, onto which a feed movement is transferred via a feed means (1-10). A direct axially parallel acting linear drive (1-06) is provided in the tool fitting unit (1) associated with the machine spindle (5) for fine feeding, the feed movement of which overlaps the first mentioned feed movement, and the actuating means (1-05) of which acts upon a feed (1-03) that is disposed together with the machining tool (2-05, 3-04) and the means for deflection (1-031, 1-032) of the feed movement in a tool unit (2, 3) that can be exchanged on the tool fitting unit (1).
