Abstract: The invention relates to a method for fine-machining a bore of a plurality of workpieces and a machine tool unit. According to said method, the workpieces are subjected to fine-hole drilling and precision finishing, preferably roller-burnishing or smoothing, a post-processing measurement is carried out and, depending on said measurement, the fine-hole drilling tool is adjusted.

Abstract: Disclosed is a rolling tool which serves for working—in particular rolling smooth—an inner lateral surface of a cylindrical clearance. For this purpose, the rolling tool has at least one rolling body, which is held in the rotatably drivable rolling tool, and can be taken along by said tool on a peripheral path along the inner lateral surface. The at least one rolling body is inserted into a radial clearance in the rolling tool and can be subjected to a pressurized fluid from the inside to the outside along the radial clearance. The fluid is an aerosol. The aerosol is a fluid mixed with gas and serves for hydrostatic bearing and lubrication.

Abstract: There is disclosed a readjustment system comprising an advancing head supporting a cutting edge and being retained on a spindle. The cutting edge is advanced by means of an actuation element adjustable by a contactless linear drive.
