Patent number: 6783444Abstract: The tool comprises a tool wheel (5) which is mounted on a holding arm (4) and has a tool-wheel parent body (6) having a machining body (7) arranged at the outer margin. In one embodiment variant, this machining body is designed as an abrasive body. A base body for accommodating the bearing arrangement is designed in one piece with the holding arm (4), which also has the supply lines (8) for the hydrodynamic bearing arrangement and the hydraulic drive. A tool-centering interface (11) permits the presetting of the tools outside the machine tool.Type: GrantFiled: October 31, 2001Date of Patent: August 31, 2004Assignee: Reinecker Kopp Werkzeugmaschinen GmbHInventors: Norbert Hessbrüggen, Christoph Wernz

Patent number: 6062969Abstract: A grinding wheel is disclosed with a disk-like, cylindrical shape, whose perimeter is equipped with a grinding abrasive and has at least one spiral groove. The groove extends essentially around the perimeter at an acute bevel angle of inclination less than 45.degree. to a radius line normal to the axis of wheel rotation. Preferably the bevel angle is designed as an acute angle and is sized so that the groove extends over at least one full circumference of the grinding wheel. The face of the ribs may be tapered and the corners chamfered. Multiple parallel or non-parallel grooves may be employed. Improved cutting, service life and surface characteristics of the processed workpiece are obtained.Type: GrantFiled: August 11, 1998Date of Patent: May 16, 2000Assignee: Kopp Werkzeugmaschinen GmbHInventor: Udo Klicpera

Patent number: 5476436Abstract: The invention concerns a chain magazine designed to hold the machining tools for machining devices, in particular tooling machines. The magazine comprises a continuous chain fitted with holder devices for the machining tools and driven by at least two sprockets and guided by guide elements up to the point of contact with the pitch diameter of the drive or guide sprocket wheel. The chain magazine further comprises chain links consisting of a connecting bar and, joined to the bar, two tubular sleeve elements of different diameter which form the flexible couplings between the links. Holder devices for machining tools are disposed coaxially to the hinge axes in the mutually encircling tubular sleeves under a small motion clearance. Shaft-like cutouts are furnished in each of the tubular sleeves and exhibiting parallel faces disposed spaced apart and directed toward the center axes of the holder devices.Type: GrantFiled: September 27, 1994Date of Patent: December 19, 1995Assignee: Kopp Werkzeugmaschinen GmbHInventor: Udo Klicpera
