20100092262 | MACHINE TOOL, AND METHOD FOR THE DAMPING OF OSCILLATORY MOVEMENTS OF A MACHINE ELEMENT OF A MACHINE TOOL - A machine tool includes a first motor, a gear, and a machine element which is movable in a direction of movement by the first motor via the gear. A second motor is provided to apply a force directly upon the machine element in the direction of movement of the machine element in the absence of an interposed gear between the second motor and the machine element. The second motor is constructed to operate in such a way that the applied force counteracts an oscillatory movement of the machine element in the direction of movement of the machine element. | 04-15-2010 |

20100215454 | CENTRIFUGALLY-CAST TUBE AND RELATED METHOD AND APPARATUS FOR MAKING SAME - An improved centrifugally-cast tube is provided, along with a related method and apparatus of making the tube. The tube includes a plurality of grooves and bosses that are mechanically machined into an interior surface of the tube, such as by a broaching process. The profile of grooves and bosses may be defined by a plurality of intersecting concave and convex radii. The tube is resistant to creep, carburization and metal dusting. The tube also has an enhanced heat transfer rate, and a desirable surface roughness. A method of making the tube is also provided. The method essentially consists of mechanically deforming the interior surface of the tube by passing a series of cutting inserts on support rings having incrementally-differing dimensions over the interior surface. An apparatus is also provided which includes a telescoping shaft upon which is mounted at least one cutting tool that has a plurality of cutting inserts and is adapted to form a plurality of grooves and bosses in the interior surface of the tube. The grooves and bosses may be straight or spiraled. | 08-26-2010 |
20100221083 | CONTROL OF WHITE-ETCHED LAYER DURING MACHINING - A machining system includes a support configured to retain an article, such as a rotor disk, having an area, such as a surface of a slot in the disk. A cutting tool, for example, a broach, is movable relative to the support to cut the area. A heating member, such as a laser, is configured to locally heat the area of the article. In one example, the cutting tool includes a body having a cutting edge. The heating member is supported by the body and is configured to provide heat adjacent to the cutting edge. The cutting edge cuts the locally heated area while the area is still heated. | 09-02-2010 |

20150132077 | Device for Keyway Broaching - A device for keyway broaching is provided with a housing, a drive shaft, a broaching carriage received and supported in the housing, a tool support connected to the broaching carriage, and a crank drive that couples the drive shaft and the broaching carriage with each other. The broaching carriage, when driven by the drive shaft, performs an oscillating movement comprising a cutting movement and a return stroke. A sleeve is arranged between the housing and the broaching carriage. A first seal is provided between the housing and the sleeve and/or between the sleeve and the broaching carriage. The tool support is connected to the broaching carriage with a rocking lever interposed between the tool support and the broaching carriage. The drive shaft has a control section that controls a relative movement between the rocking lever and the broaching carriage. | 05-14-2015 |

20090080991 | Tool - The invention relates to a disc-shaped or strip-shaped tool for machining, particularly, for cutting profiles on a workpiece such as a crankshaft that is rotated during machining, comprising a number of tangentially and radially mounted indexable inserts ( | 03-26-2009 |
20100104390 | BROACHING TOOL, IN PARTICULAR KEYWAY BROACHING TOOL - The invention relates to a broaching tool, in particular a keyway broaching tool, comprising a holder which defines a longitudinal axis and has a shank, extending in the longitudinal direction, as support for a cutting body which can be fixed in a seat of the shank by means of a clamping device. The seat has a passage which is at a distance from the free end of the shank and extends transversely to the longitudinal axis and the inside of which forms guide surfaces for bearing surfaces of the cutting body, which can be inserted into the passage in an insertion direction. An end-position limit for the inserted cutting body is formed on guide surfaces and on associated bearing surfaces. The clamping device produces a force component on the cutting body which presses the latter against the end-position limit. | 04-29-2010 |
