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 for the fine machining of a circumferential workpiece surface and method for operating the device

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.

Finishing device for finish machining of a workpiece, in particular of a crankshaft or a camshaft

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.

Device for band finishing a workpiece

The invention relates to a pressing device for pressing a finishing belt against a workpiece surface, including a pressure belt and a pressure belt carrier which supports the pressure belt at two mutually spaced-apart support points, wherein the pressure belt is fastened releasably to the pressure belt carrier, wherein, in order to fix in each case one pressure belt end, provision is made of a fixing device that is provided separately from the pressure belt carrier, and wherein the fixing device is fastened or fastenable releasably to the pressure belt carrier in a state in which one pressure belt end is fixed to the fixing device.

Pressing device for pressing a finishing belt against a workpiece surface

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.

Device and system for finish-machining a workpiece in the form of a crankshaft or a camshaft

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.

A finishing device for finish-machining of a workpiece includes a force-generating device for generating a driving force, a force-transmitting arm and a pressing device for applying a working force to a finishing tool, and further a measuring device for measuring a deformation of a segment of the force-transmitting arm arranged in the force flux between the driving force and working force and/or for measuring a deformation force applied in the segment.

Finishing device for finish-machining of a workpiece

The disclosure relates to a finishing apparatus for finish machining of rotationally symmetric workpiece surfaces having a finish belt guide which has a guiding body for guiding the finish belt, wherein the guiding body comprises a shell-like guiding surface along which the finish belt can be guided or is guided between an insertion end of the finish belt and a withdrawal end of the finish belt, wherein the guiding surface is mounted in a resiliently elastic manner in the radial direction, wherein, when seen in the circumferential direction, the guiding surface extends in a continuous manner between the insertion end of the finish belt and the withdrawal end of the finish belt over at least a part of the width of said guiding surface and is mounted in a resiliently elastic manner.

Finishing apparatus with resiliently mountable finishing belt guide

The invention concerns a device for belt-grinding curved material surfaces, wherein the abrasive belt is pressed onto the surface of the work piece by means of two processing shoes and at the same time, the surface of the work piece to be processed is measured by an in-processing means.
