20140134925 | METHOD AND DEVICE FOR FINISHING A WORKPIECE SURFACE - A method for finish-machining a workpiece surface includes moving the workpiece surface relative to an active area of the finishing tool in a rotation direction about a workpiece axis, and superimposing on the relative movement of the workpiece surface and the active area an additional oscillatory movement with an oscillation frequency lower than 20 kHz in a direction perpendicular to the workpiece surface. | 05-15-2014 |
20140094099 | BELT FINISHING DEVICE, BELT FINISHING SYSTEM AND METHOD FOR PRODUCING A BELT FINISHING DEVICE - A belt finishing device includes a finishing belt, two bearing surfaces that are spaced-apart in a running direction of the finishing belt, and a pressing device for pressing the finishing belt against a workpiece surface. The pressing device has a pressure belt that is supported on the two spaced-apart bearing surfaces. At least one of a bearing surface and the pressure belt have a profile that deviates in a width direction of the finishing belt from a straight course. | 04-03-2014 |
20130189909 | DEVICE FOR FINE-MACHINING A PERIPHERAL WORKPIECE SURFACE LOCATED ECCENTRICALLY IN RELATION TO A WORKPIECE AXIS OF A WORKPIECE - A device for fine-machining a peripheral workpiece surface which is arranged eccentrically in relation to a workpiece axis of a workpiece, in particular of a pin bearing of a crankshaft, includes a rotary drive device for rotatably driving the workpiece about the workpiece axis, a pressing device for pressing a fine-machining tool against the peripheral workpiece surface, and a bearing device for supporting the pressing device on a frame. The device further includes a force application device which applies deceleration and/or acceleration forces on a bearing member of the bearing device, with the bearing member moving back and forth between two reversal positions when the workpiece rotates. | 07-25-2013 |
20120122375 | DEVICE FOR MEASURING THE FEED MOTION OF A FINISHING BELT - A device for measuring the feed motion of a finishing belt includes a movable contact section for contacting the finishing belt, wherein a movement of the finishing belt can be transferred to the contact section, and a sensor device including a sensor and a reference section cooperating with the sensor, wherein the reference section or the sensor is motionally coupled with the contact section. | 05-17-2012 |
20110312256 | FINISHING DEVICE FOR FINISHING A SURFACE OF A WORKPIECE - A finishing device for finishing a surface of a workpiece includes a finishing belt, and a guide unit for guiding the finishing belt. The guide unit has a cup-shaped guide surface which bounds a receiving zone for the workpiece and along which the finishing belt is guided or guidable between an entry zone and an exit zone. The guide unit includes at least two separate guide members which have each a surface area, with the surface areas of the guide members jointly defining the guide surface and being movable relative to one another. | 12-22-2011 |
20100317266 | WORKPIECE HOLDER FOR A SURFACE GRINDING MACHINE - The present disclosure relates to a workpiece holder for a surface grinding machine, with a central workpiece holder shaft around which the workpiece holder can be driven in rotation, with at least one workpiece fixture to hold at least one workpiece, and with at least two holder parts movable relative to one another that jointly define the at least one workpiece fixture and that can be fixed relative to one another by means of a joining device. | 12-16-2010 |
20100317259 | SURFACE GRINDING MACHINE AND METHOD FOR ADJUSTING A SURFACE GRINDING MACHINE - The present disclosure relates to a surface grinder having at least one grinding tool, a workpiece holder for holding at least one workpiece, a drive unit for driving the workpiece holder in a rotational direction and a clutch device that provides a rotationally fixed connection between the drive unit and the workpiece holder that can be released at a specifiable limit torque. | 12-16-2010 |
20100210187 | Device and method for fine or finest processing of a rotationally symmetric work piece surface - A device for fine or finest processing of a rotationally symmetric work piece surface of a work piece ( | 08-19-2010 |
20100112913 | FINISHING MACHINE WITH STONE ROTATING UNIT - A finishing machine with at least two finishing stones and a stone turning unit is proposed, in which the stone turning unit may be coupled to a rotary drive of the workpiece holder. A separate drive for the stone turning unit may thus be omitted, which results in a reduced weight of the stone turning unit and therefore lower drive power requirement of the stone turning unit and an improved processing quality. | 05-06-2010 |
20100050405 | DEVICE FOR PRECISION MACHINING OR MICROMACHINING WORKPIECES - The disclosure relates to a device for precision machining or micromachining workpieces, with a feed mechanism for transporting at least one workpiece, with a storage device, which includes a magazine for storing at least one workpiece, and with a tool for machining at least one workpiece, wherein the at least one workpiece can be led out of the magazine of the storage device to the feed mechanism, wherein the feed mechanism can be moved such that a workpiece held on the feed mechanism can be transported to the tool, wherein the magazine of the storage device can be moved along a magazine motion path, whose course is aligned at least in part with a workpiece motion path, which is traversed by a workpiece held on the feed mechanism during the transport from the magazine of the storage device to the tool. | 03-04-2010 |
20100000371 | Adjustable Eccentric Drive - An adjustable eccentric drive is disclosed, including a first shaft and a crank pin connected to the first shaft, wherein a radial distance between the crank pin and an axis of rotation of the first shaft is adjustable with an adjusting collar; and a method for adjusting the stroke of an oscillating tool in a tool machine using the adjustable eccentric drive is disclosed. | 01-07-2010 |
