Patent number: 10322490Abstract: A honing tool has a tool body and shells disposed on the tool body. Honing stone sets each provided with two or more honing stones are provided. The shells each support one of the honing stone sets. Guide bars of the honing tool are placed against the bore and a portion of the bore is conically honed with decreasing stroke of the honing tool, wherein a lower reversing point of the honing tool remains substantially unchanged. Honing is terminated as soon as an upper reversing point has reached a predetermined terminal value. Alternatively, a portion of the bore is conically honed with a constant stroke of the honing tool, wherein reversing points of the stroke of the honing tool remain substantially unchanged and a feeding force pressing the honing stones against the bore is controlled as a function of a position of the honing tool in the bore.Type: GrantFiled: October 22, 2016Date of Patent: June 18, 2019Assignee: Gehring Technologies GmbHInventors: Gerhard Flores, Erwin Baumgartner, Manuel Waiblinger, Andreas Wagner

Patent number: 10086491Abstract: 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.Type: GrantFiled: November 12, 2014Date of Patent: October 2, 2018Assignee: GEHRING TECHNOLOGIES GMBHInventors: Erwin Baumgartner, Michael Rach

Patent number: 10040158Abstract: 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.Type: GrantFiled: February 11, 2015Date of Patent: August 7, 2018Assignee: Gehring Technologies GmbHInventors: Andreas Wiens, Andreas Wagner, Gerhard Flores, Manuel Waiblinger

Publication number: 20140113535Abstract: 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.Type: ApplicationFiled: October 18, 2013Publication date: April 24, 2014Applicant: GEHRING TECHNOLOGIES GMBHInventors: Erwin Baumgartner, Jörg Necker, Klaus Fleckenstein, Andreas Senke, Frank Hummel, Alexander Christian Weber
