Abstract: The present disclosure relates generally to the field of surface finishing operations, more particularly to micro-finishing systems and processes. The micro-finishing system and process of the present disclosure is configured to perform surface finishing operation on a work-piece. The micro-finishing system comprises: (i) a micro-finishing film having a layer of abrasives which is configured to be rubbed against the work-piece, (ii) a contact tooling which is configured to provide support to the micro-finishing film, and (iii) ports which are configured within the contact tooling strategically to reduce heat and frictional losses generated due to rubbing of the layer of abrasives against the work-piece by a minimum flow of coolant at the desired location. The ports are typically drilled holes.

Abstract: A method for manufacturing an assembled camshaft for valve-controlled internal combustion engines, in which at least one cam disc with a base circle region and cam region is machined on the running surface and has a cam-disc recess, includes shrinking the cam disc onto a corresponding shaft designed with a defined dimensional overlap by cooling the shaft and heating the cam disc. Temporally before being shrunk onto the shaft, the at least one cam disc is clamped by a clamping device such that a tension force acts on the recess wall region, which defines the cam-disc recess, the tension force corresponding to a predetermined extent to the state of stresses and/or deformation state of the recess wall region after the operation of shrinking the cam disc onto the corresponding shaft. The running-surface machining of the at least one cam disc takes place when the cam disc is clamped by the clamping device.

Abstract: A cam grinding method using a cam grinding device includes: an intermediate-cam lift-data generating step of, based on first lift data of a first cam and second lift data of a second cam, generating imaginary intermediate cam lift data of a spline curve that contains profiles of both cams; a first cam grinding step of grinding the first cam; a second cam grinding step of grinding the second cam; and an intermediate-cam grinding step of removing an unground portion generated at a boundary portion between the first cam and the second cam by plunge grinding or spark-out grinding on the basis of the intermediate-cam lift data after the second cam grinding step.

Abstract: 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.
