Patent number: 6796012Abstract: A milling and drilling machine for rod-shaped material. A motor-driven spindle head is movable on a column along a first coordinate axis and includes a work spindle capable of selectively accommodating milling and turning tools. A separating device transversely separates the rod-shaped material. A clamping device, disposed laterally alongside the workspace, has a workpiece holder with a clamping axis along a horizontal coordinate axis. A rotary drive is provided for the workpiece holder. The spindle head is pivotable about a Y axis at the front side of a headstock movable in the direction of the Y coordinate axis. The headstock is disposed on a motor-driven slide movable on the stationary column along an X coordinate axis parallel to the workpiece clamping axis. The clamping device is disposed on an inclined console located on the face of the column and movable along the Z coordinate axis in guides.Type: GrantFiled: February 21, 2003Date of Patent: September 28, 2004Assignee: Deckel Maho Pfronten GmbHInventors: Alfred Geissler, Karl Lechleiter, Reinhold Seitz

Patent number: 5301405Abstract: The milling machine lathe attachment is attachable to an existing milling machine so as to eliminate the need for an operator owning both a milling machine and a lathe. It is designed to be mounted to the side of the milling machine and to be used without disturbing a setup in the associated vise. The attachment is also designed to be mounted to the front of a milling machine and allows the programming of the very point of single point tool contact so as to follow whatever contour or steps are desired. This type of cutting is not possible on a lathe with guaranteed accuracy, while on a milling machine it is quite feasible.Type: GrantFiled: January 11, 1993Date of Patent: April 12, 1994Inventor: Richard A. Maker

Patent number: 5090278Abstract: A lathe with a machine bed, a main spindle stock for a motor driven main spindle fixed to the machine bed, a tail stock moveable in the direction of the main spindle axis, and a cross table including a longitudinal table moveable in the direction of the main spindle axis and a transverse table transversely moveable relative to the longitudinal table, with the longitudinal table being operable by a rotatable longitudinal lead screw and with the transverse table being operable by a rotatably drivable transverse lead screw. The longitudinal lead screw and the transverse lead screw are each provided with a hand wheel, which hand wheel is rigidly connected with a driving wheel couplable to an associated drive motor. The drive motors are controllable by a data processor.Type: GrantFiled: September 4, 1990Date of Patent: February 25, 1992Assignee: Emco Maier GmbHInventors: Hans Mair, Johan Reiner

Patent number: 4911043Abstract: A device and method for milling a trochoidal rotor having a predetermined trochoidal configuration. The trochoidal rotor is used in a trochoidal rotary device in which working chambers are defined between the rotor and a housing. The rotor device has inlet and outlet ports for passing a fluid or gas. The rotor is made by first planetating a rotor blank having a predetermined width and having an edge region about a predetermined axis. The cutting blade is provided which has a predetermined geometry and which is located at a predetermined fixed distance from the axis. The cutting blade is engaged with at least a portion of the edge region of the rotor blank. The cutting blade traverses the edge region of the rotor blank to cut the edge region into a predetermined trochoidal configuration. When the cutting blade is a helical flute, the engagement of the cutting blade with a portion of the edge region results in cutting at a predetermined location within the portion of the edge region.Type: GrantFiled: March 14, 1989Date of Patent: March 27, 1990Assignee: Compression Technologies, Inc.Inventor: Ralph M. Hoffmann

Patent number: 4852434Abstract: A machine tool having a work spindle with an electrically actuated clamping unit including a three-phase motor with a stationary stator. The motor is supplied with electricity from a control unit operating with frequency conversion, and the control unit is alternatingly also used for triggering a spindle drive motor. A sensor detects clamping force applied to a workpiece, and produces a signal used to reduce motor speed of the three-phase motor until a predetermined clamping force is achieved.Type: GrantFiled: April 19, 1988Date of Patent: August 1, 1989Assignee: Paul Forkardt GmbH & Co. KGInventor: Hubert Bald

Patent number: 4706529Abstract: A clamping ring for use in pipe joints has an inside surface which is formed with generally peripherally extending indentations for axially fixing a pipe. In order to prevent an occurrence of dangerous stress concentrations in pipes in contact with such clamping rings and to permit such rings to be manufactured economically, the clamping ring is formed on its inside surface with a multiplicity of generally peripherally extending indentations, each of which extends only along part of the periphery of said inside surface, and said indentations are offset from each other in said peripheral directions and adjoint or overlap.Type: GrantFiled: October 23, 1986Date of Patent: November 17, 1987Assignee: E.

Patent number: 4538945Abstract: In an apparatus for machining polygon profiles, comprising a workpiece spindle and a tool spindle (12) driven in synchronism therewith and carrying an eccentric tool (22), wherein the transmission ratio between the workpiece spindle and the tool spindle as well as the lateral distance therebetween are adjustable, the invention provides for additional adjustment of the eccentricity of the tool. This permits one and the same tool to be employed for pre-cutting various polygon profiles of any standard nominal size in a rational manner and with close approach to the final profile shape. The cutting speed is increased by providing a disk-shaped counterweight (21) with adjustable eccentricity located on the tool spindle adjacent the tool. A common adjustment means (18, 24 to 27) is effective to automatically adjust the eccentricity of the counterweight in correspondence to the respective eccentricity of the tool.Type: GrantFiled: September 28, 1983Date of Patent: September 3, 1985Assignee: Krones Ag Hermann Kronseder MaschinenfabrikInventors: Paul Godecke, Otto Meichel
