Abstract: In a process and an apparatus for centerless superfinishing of rollers with arbitrarily curved jacket faces by means of an oscillatingly driven honing stone, the rollers are transported in the continuous process and the honing stone moves together with the rollers at the same speed or at superimposed speeds. The rollers rotate relative to their associated honing stone as a result of being transported causing machining to occur.

Abstract: The invention relates to an apparatus for fine-working or microfinishing of workpiece surfaces, particularly rotationally-symmetrically moved workpieces with oscillating or rotating tools such as honing stones or fine polishing stones, which are in-fed against the workpiece. Dependent on a measured parameter proportional to the machining force, the tool infeed is controlled such that a continuous workpiece material remove with constant removal speed is achieved. The reaction force is measured at any point in the flux of force to determine the machining force.

Abstract: The invention relates to a method and an apparatus for fine-working or microfinishing of workpiece surfaces, particularly rotationally-symmetrically moved workpieces (38) with oscillating or rotating tools such as honing stones (18) or fine polishing stones, which are infed against the workpiece (38). Dependent on a measured parameter proportional to the machining force, the tool infeed is controlled such that a continuous workpiece material remove with constant removal speed is achieved. The reaction force is measured at any point in the flux of force to determine the machining force.

Abstract: In a continuous flow machine with a centerless finishing device for honing external cylindrical surfaces, the device includes a plurality of successive finishing elements with individually feedable finishing stones and a common oscillation drive for oscillation the finishing elements. The device further includes a measuring device to measure the oscillation movement of the finishing elements powered by the common drive. There is a computer which receives the measured signal and compares it to a desired value. Depending on the previous result, an adjustable control means, connected to both the computer and the common drive, will adjust the common drive to perform the necessary oscillation movement of the finishing elements.

Abstract: A method and an apparatus are described for superfinishing convex or concave jacket faces of rotationally symmetrical workpieces, in particular of roller bearing rollers, in which the workpiece is received and rotated between two rotatable rollers, at least one of which is driven, while a honing stone is lowered perpendicularly to the longitudinal axis of the workpiece against the jacket face and thereby executes an oscillation parallel to the longitudinal axis of the workpiece. Along at least a portion of its stroke movement, the honing stone is imparted a further oscillation, synchronous with the first, along a curved path located in the jacket face of the workpiece.
