A finishing device includes a finishing tool having a grinding face and a finishing-tool holder configured to hold the finishing tool. The finishing-tool holder is movably guided on a pivot support which is pivotable about a pivot axis. A force-generating apparatus is configured to generate a pressing force, by means of which the grinding face of the finishing tool is pressed against a workpiece to be machined. The force-generating apparatus is arranged on a mounting apparatus for pivotally mounting the pivot support. A force-transmitting apparatus is configured to transmit the pressing force from the force-generating apparatus to the finishing-tool holder.

A device for the fine machining of a circumferential workpiece surface arranged eccentrically relative to an axis of a workpiece. The device comprises a pressure mechanism configured to press a fine-machining tool against the circumferential workpiece surface. The device also includes a drive unit configured to drive an active section of the pressure mechanism via a first drive and a second drive. The first drive drives the active section in a movement plane that runs crosswise to the workpiece axis along a first movement trajectory. The second drive drives the active section along a second movement trajectory that is at an angle to the first movement trajectory.

Device and method for the finishing machining of an internal face of a workpiece, such as the track of a ball screw, including a workpiece holder and a finishing tool held on a finishing tool holder. A rotary drive is provided, by which the workpiece holder and the finishing tool is rotationally driven relative to one another about a rotational axis. A linear drive is provided, by which the finishing tool held on the finishing tool holder and the workpiece holder is driven in a translatory manner relative to one another along the rotational axis. An oscillating drive is provided, by which the finishing tool held on the finishing tool holder and the workpiece holder is driven in an oscillating manner relative to one another in the direction parallel to the rotational axis and wherein the finishing tool is pivotably held on the finishing tool holder about a pivot axis.

A device for finishing a workpiece includes two pressing elements and a holding apparatus for holding the pressing elements. A finishing band is pressable against a workpiece surface to be finished. A flexurally resilient intermediate element is disposed so as to transmit a pressing force to the finishing band by means of a force-receiving surface and by means of a force-transmitting surface. The intermediate element or a plurality of them is configured to transmit pressing forces, which are offset relative to one another in a circumferential direction of the workpiece surface, to the finishing band. The force-transmitting surfaces of the intermediate element or the plurality of them are oriented in a substantially V-shaped manner relative to one another, and are substantially planar in an undeformed initial state and have a curvature in a same direction as the workpiece surface when there is a pressing force.

A device for finish-machining a workpiece in the form of a crankshaft or a camshaft includes a workpiece holder and a rotational drive configured to rotate the workpiece about a workpiece axis. A first finishing tool is configured to machine a main bearing which is concentric with the workpiece axis. A second finishing tool is configured to machine an additional bearing which is radially offset from the workpiece axis. A first tool drive is configured to generate an oscillating movement of the first finishing tool in a direction parallel to the workpiece axis. A second tool drive is configured to generate an oscillating movement of the second finishing tool which is independent of the movement of the first finishing tool in a direction parallel to the workpiece axis.

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.
摘要:
A finishing device for finish machining of a workpiece, in particular of a crankshaft or a camshaft, comprising a workpiece holder and a rotary drive for rotating the workpiece about the workpiece axis thereof, comprising at least one first finishing tool for machining a main bearing concentric to the workpiece axis and at least one second finishing tool for machining an additional bearing, wherein the finishing tools can be moved along a transport axis which extends via a working area defined by the workpiece holder so that the finishing tools can be moved into an additional area arranged outside the working area.
