Patent number: 8172489Abstract: The present invention relates to a machine tool for machining of workpieces, having a workpiece support for mounting the workpiece, a tool holder, which can be moved at least along one axis, for holding a tool for machining the workpiece, and workpiece holding units for fixing the workpiece during the machining, the workpiece holding units being arranged outside the workpiece support surface of the workpiece support, which is covered by the workpiece in the mounted state, and each having a holding element for fixing the workpiece. In order that also workpieces of greater diameter can be machined, the machine tool otherwise being of the same dimensions, it is provided according to the invention that the holding elements can each be moved, substantially parallel to the workpiece support surface, in the direction of the workpiece, in particular in the direction of a central workpiece axis, which runs perpendicular to the workpiece support surface, for the purpose of centering and fixing the workpiece.Type: GrantFiled: August 31, 2010Date of Patent: May 8, 2012Assignee: Chiron-Werke GmbH & Co. KGInventors: Dirk Prust, Hans-Henning Winkler, Torsten Winkler

Patent number: 5960686Abstract: An alignment pin has a first cylindrical portion having a first diameter equal to the outer diameter of a work piece, and axially aligned therewith is a second cylindrical portion having a second diameter equal to the inner diameter of a work piece. The pin is inserted into a tube squaring machine to align the cutting tool of the machine for squaring a work piece having outer and inner diameters equal to the first and second diameters of the pin.Type: GrantFiled: June 23, 1997Date of Patent: October 5, 1999Assignee: The E. H. Wachs CompanyInventor: William Bonow

Patent number: 5797708Abstract: A universal drill guide (10) comprising a base (12) being a frame-like configuration having a large central opening. A pair of elongated columns (14) are provided. A structure (16) is for pivotally mounting lower ends of the elongated columns (14) parallel to opposite sides of the base (12), so that the elongated columns (14) can go from upright positions to angled positions. A cross slide (18) rides upon the elongated columns (14). A bearing spindle assembly (20) is rotatively carried centrally within the cross slide (18). A guide chuck (22) is connected to the bearing spindle assembly (20) above the base (12). An adjustable cradle (24) is affixed to the cross slide (18) to hold an electric drill (26) in a stationary position, so that the drill chuck (28) can engage with the bearing spindle assembly (20) above the cross slide (18). A facility (30) is between the cross slide (18) and the elongated columns (14), for moving the cross slide (18) up and down on the elongated columns (14).Type: GrantFiled: April 2, 1997Date of Patent: August 25, 1998Inventor: Stjepan Bencic

Patent number: 5092205Abstract: An apparatus including a cylindrical body defined by forward and rear threaded end portions to receive a respective forward and rear collar. The forward collar is cooperative with pivotally mounted wedge plates that cooperate with the forward collar to direct associated presser feet into engagement with an associated workpiece to coaxially clamp the workpiece internally of the cylindrical body. The rear collar includes an internally threaded component for cooperation with the rear threads and a radially aligned cutter blade that is directed overlying the workpiece to effect cutting of the workpiece during rotation of the rear collar relative to the workpiece while clamped within the cylindrical body.Type: GrantFiled: May 29, 1990Date of Patent: March 3, 1992Inventor: Bernard L. Gwyn

Patent number: 4739682Abstract: A tube and rod end finishing machine embodies a generally tubular portable housing within which a spindle carrying a finishing tool is axially movable. An end of the housing adjacent the tool forms one jaw of a clamshell work holder, the other jaw of which is pivoted on the housing on an axis normal to and intersecting the axis of the spindle, for movement toward and away from clamping relationship with said first mentioned jaw.Type: GrantFiled: July 3, 1986Date of Patent: April 26, 1988Inventor: Orville J. Birkestrand
