An ultrasonic peening-type integrated machining method for cutting and extrusion includes: applying transverse ultrasonic vibration or a vibration component, which is vertical to a cutting speed direction to a cutting tool on a machine tool; setting a cutting parameter and an ultrasonic vibration parameter such that a dynamic negative clearance angle is generated in a cutting procedure and a flank face of the cutting tool conducts ultrasonic peening extrusion on the surface of the workpiece; setting an extrusion overlap ratio; setting a wear standard of flank faces extruded by the cutting tool; controlling a vibration cutting trajectory phase difference of the cutting tool during two adjacent rotations; and turning on the machine tool in order to ensure that cutting and surface extrusion strengthening of the workpiece are completed in one procedure without separate strengthening procedures. The method conducts extrusion strengthening on the surface of the workpiece while cutting the workpiece.

Various examples are provided for polishing techniques for flexible tubular workpieces. In one example, a method includes supporting a tubular workpiece on a rod that extends axially through it; positioning a turning wheel against an external surface of the tubular workpiece, where it is held by magnetic attraction; and rotating the tubular workpiece by rotating the turning wheel. The external surface of the tubular workpiece is polished by the abrasive particles during rotation of the tubular workpiece. In another example, a polishing system includes a workpiece holder including a rod configured to axially support a tubular workpiece; a turning wheel with abrasive particles distributed about an outer surface; a wheel support assembly configured to position the outer surface of the turning wheel against the an external surface of the tubular workpiece, where it is held by magnetic attraction. The external surface is polished during rotation of the tubular workpiece.

A masking tool system includes a first masking body and a second masking body. The first masking body includes a bore passing through a portion of the first masking body and a first sealing element disposed on a first end of the first masking body. The second masking body includes a bore passing through the second masking body and a second sealing element disposed on a first end of the second masking body. The system may also include a rod configured to pass through the bores of the first and second masking bodies and to secure the first and second masking bodies to a metallic article placed therebetween. A diagonal length of the masking tool system induces a wobbling rotation during processing.

A finishing apparatus includes a workpiece-receiving device, a rotary drive configured to drive a workpiece in rotation about a workpiece axis and an oscillatory drive configured to produce a relative movement between the workpiece and a finishing tool in a direction that is parallel to the workpiece axis. A workpiece-conveying device has a workpiece holder that is moveable by a drive device between a working position in which the workpiece is in position to be machined and a loading/unloading position in which the workpiece is loadable/unloadable. The workpiece holder has a support device configured to support the workpiece. The drive device is formed as a swivel drive such that the workpiece holder is swivelable between the working position and the loading/unloading position along an arcuate swivel path.

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.
