In a method for finish machining of peripheral surfaces of rotationally symmetrical workpiece sections on workpieces, a finishing tool (100) comprising a pressing force in a pressing direction (AR) is pressed on the peripheral surface to be machined when a peripheral surface is machined. In order to produce material removal, the workpiece is rotated about a workpiece axis (192) and an oscillating relative movement is produced between the finishing tool and the workpiece In order to produce the oscillating relative movement, the finishing tool is moved back and forth along an oscillation direction with a predeterminable oscillation stroke length and oscillation frequency. A linear movement of the finishing tool running parallel to the workpiece axis is superimposed on the oscillation movement over a linear stroke length. A pivoting movement of the finishing tool about a pivot axis running perpendicular to the workpiece axis and to the pressing direction is superimposed on the linear movement and oscillation movement. A pivot position of the finishing tool is controlled in relation to the axial position of the linear movement. In this way, different axial surface line profiles can be produced in a targeted manner by means of finishing in order, for instance, to obtain a convex shape of the workpiece sections.

Abrégé

A pressing device (50) for pressing cutting means onto circumferential surfaces (12) of substantially cylindrical parts (13) of a workpiece during a finishing operation is intended for pressing the cutting means onto a circumferential surface with a pressing force over an angle of approach. The pressing device is infinitely adaptable for the working of parts of a workpiece of different diameters, with a difference in diameter of at least 0.1 mm.

According to a method for the fine machining of internal surfaces of bore holes in tools by fine boring and subsequent honing, the following steps are executed: Fine boring of at least one bore hole (131) in a tool (130) by means of a fine boring tool (128) of a fine boring device (120) for the creation of a fine bored bore hole; Transfer of the tool to a machining position of a honing device (140) for the machining of the fine bored bore hole by means of a honing tool (148A) of the honing device; Measurement of the fine bored bore hole with one of the measurement devices (160) allocated to the honing device in the machining position for the creation of at least one bore hole measurement signal representing the properties of the fine bored bore hole. The fine boring device is controlled subject to the bore hole measuring signal.

Abrégé

Disclosed is a method for measuring a surface on a workpiece with the aid of at least one sensing probe (180) which is provided with a probe member and at least one sensor (185) that is mounted on the probe member. Said method is designed particularly for determining the surface structure of cylindrically curved inner surfaces or outer surfaces on workpieces. At least one optical sensor (610) is used for taking the measurement, and a gap between the sensor and the surface of the workpiece in a measuring zone is filled with a liquid (631) that is transparent to the measuring radiation.
