ABSTRACT:
A head rotatable about an axis for machining and simultaneously polishing the peripheral surfaces of shafts or the like, comprises a support plate provided with a central opening through which a shaft to be machined and polishing may extend. A plurality of tool supports are mounted in a star-like manner on the support plate adjustable in radial direction toward a shaft extending through the central opening. The tool supports alternatingly carry at inner ends knives or polishing rolls. A central adjustment device is provided for simultaneously adjusting of the tools carried by the tool supports through equal distances in radial direction toward the workpiece. The central adjustment is carried out by a plurality of angular drives, each including a bevel gear for each tool support and at least one gear ring with which the bevel gears mesh. It is also possible to adjust all tool supports carrying the knives independent from all tool supports carrying the polishing rolls in which case two gear rings are provided which are turnably mounted on the support plate concentric with the axis of the head.
