Another connecting rod is articulated on the machining head and on a second Y carriage and the second Y carriage is capable of displacement along Y on a second X carriage capable of displacement along X. The relative movement along X of the Y carriages results in a displacement in the Z direction. Several devices can be positioned in a plurality of tunnels, these tunnels being arranged so as to share several things.Type: GrantFiled: September 21, 2007Date of Patent: October 22, 2013Assignee: Airbus Operations SASInventors: Andre Greffioz, Michel Vives

Patent number: 8529420Abstract: A machine tool for achieving a high degree of flexibility during workpiece processing comprises a machine bed with side walls arranged thereon, which respectively comprise a basic body with a front overhanging projection arranged thereon. On the side walls a tool spindle is arranged to be linearly movable by means of slides. Underneath the front overhanging projections a processing space is formed for the workpiece processing, in which a workpiece positioning unit is arranged. The processing space underneath the front overhanging projections is freely accessible, whereby depending on the processing task different workpiece positioning units can be arranged therein.Type: GrantFiled: June 15, 2010Date of Patent: September 10, 2013Assignee: MAG IAS GmbHInventors: Moshe Israel Meidar, Wolfgang Horn, Bernhard Pause, Waldemar Haus, Joachim Krischke, Heiner Lang

Publication number: 20130078046Abstract: A protecting cover for an X-axial screw of a carving machine includes a driven base positioned between an X-axial sliding base and an X-axial screw, and a hood. A through groove is bored in the driven base for the hood to pass through to surround the X-axial screw, enabling the driven base to move freely along the hood to effectively protect the X-axial screw. And as the hood doesn't have to be extended or compressed while the X-axial sliding base is moving, it can avoid the disadvantage of being easily broken that would happen to a conventional one owing to constant extending and compressing. So the protecting cover of the invention is pretty reliable.Type: ApplicationFiled: September 22, 2011Publication date: March 28, 2013Inventor: Bor-Yann CHUANG

Patent number: 8388283Abstract: An apparatus for collecting weld tip chips created by a weld tip dresser is provided that “catches” the chips at the cutting tool and collects them in a container, preventing their disbursement on the factory floor. The apparatus includes a body adapted for connection to the weld tip dresser and with an opening therethrough configured to permit the weld tip dresser therethrough. The body defines an air inlet passage extending from an outer surface of the body to the opening. The body defines an air outlet passage from the opening to the outer surface. A pressurized air supply is connected to the body at the air inlet passage and is configured to blow air through the air inlet passage to blow chips from the opening through the air outlet passage. A container is operatively connected to the body at the air outlet passage for collecting chips blown from the opening.Type: GrantFiled: December 8, 2008Date of Patent: March 5, 2013Assignee: GM Global Technology Operations LLCInventors: Randall H. Decker, Robert C. Kennedy, Mark R. Churitch

Publication number: 20130039713Abstract: Modular machine tools, modular machine-tool beds, and systems for assembling the same are disclosed. Some machine tools and beds may be configured selectively between a cantilever configuration and a gantry configuration. Some modular beds may be assembled selectively to have a desired longitudinal length. The modular nature of the machine tools and modular beds allows users to configure a machine tool in multiple configurations depending on a particular work piece needing to be worked.Type: ApplicationFiled: August 12, 2011Publication date: February 14, 2013Applicant: Climax Portable Machine Tools, Inc.Inventors: Darren Paul Weidman, Hitesh K. Patel, John Winfrey Dillman, Garrett Lindon Headrick
