20140352997 | MOTOR SPINDLE - The invention relates to a motor spindle comprising at least one spindle drive which can be supplied with energy and/or operating supplies via at least one feed line. This motor spindle has a fixedly installed first coupling element of a multi-coupling, to the ports of which the feed lines for transmitting energy and/or operating supplies are connected. The invention also relates to a machine tool comprising such a motor spindle, wherein the machine tool has a second coupling element of the multi-coupling. On this second coupling element, the respective complementary ports for transmitting energy and/or operating supplies are arranged. | 12-04-2014 |
20130025124 | Method and Machining Installation for the Finishing of a Crankshaft Bearing Bore - In a method for the finishing of a crankshaft bearing bore in a cylinder crankcase of an internal combustion engine, starting from a prepared crankshaft bearing bore, a finished crankshaft bearing bore is produced with a prescribable desired size, a prescribable desired structure of the bore inner surface and a prescribable desired position of the bore axis. The prepared crankshaft bearing bore is first finished with at least one finishing tool with a geometrically defined cutting edge and then the honing of the crankshaft bearing bore is carried out. In a final finishing operation with a geometrically defined cutting edge immediately preceding the honing, an allowance of at least 0.4 mm is removed, and the honing tool is introduced into the bore coaxially in relation to the desired position of the bore axis and moved within the bore, an allowance of at least 0.08 mm being removed during the honing. | 01-31-2013 |
20120184182 | METHOD FOR COMBINED FINE BORING AND HONING MACHINING, AND MACHINING PLANT FOR EXECUTING THE METHOD - A method for fine boring of internal surfaces of bore holes in work pieces as well as a machining plant for executing this method. The fine machining, fine boring, and honing include fine boring of a bore hole of a work piece using a fine boring tool; transferring the work piece into a honing device; measuring the fine bored bore hole with a measuring device associated with the honing device; and controlling the operation of the fine boring device depending on the bore hole measuring signal received by the measuring device. An output fine boring machining, arranged directly upstream of the transfer, is dimensioned as semi-finishing machining, and is carried out with a fine boring tool having at least one adjustable cutting edge. The position of the adjustable cutting edge is controlled depending on the bore hole measuring signal. | 07-19-2012 |
20120073092 | CLAMPING DEVICE AND METHOD OF CLAMPING - The invention refers to a clamping device and a method for clamping an article, wherein a clamping means connected with the article interacts with clamping elements of the clamping device by a clamping motion for the releasable clamping of the article, and the at least one clamping element can be moved by a clamping drive along a clamping direction, and additionally the clamping element is movable in a compensation direction differing from the clamping direction, in order to allow centering and afterwards clamping of the article. | 03-29-2012 |
20110217136 | MACHINE TOOL - A machine tool for machining work pieces. It has a machining tool. This is held in a tool mount. For that a tool clamping device is provided. An electric motor serves for generating the clamping power, or at least one means driven by the electric motor acts on a spring arrangement for effecting the release of the machining tool from the tool clamping device. | 09-08-2011 |
20110214540 | Machine Tool With a Drive Shaft - Machine tool for machining one or more work piece(s) with a drive shaft driven by a drive with an adapter fitting for the optional connection of the drive shaft with a clamping device or a lathe chuck. | 09-08-2011 |
