Abstract (en)

[origin: WO2015197449A1] A finishing tool (300) for finish-machining a rotationally symmetric workpiece portion of a workpiece which rotates about a workpiece rotation axis during the finish-machining has a cutting means carrier (310) and a cutting layer (320) which is fastened to the cutting means carrier. The cutting layer has a cutting face (325) which is intended to be pressed flat against the workpiece portion during finish-machining. The cutting layer defines a longitudinal direction (L) to be oriented substantially parallel to the workpiece rotation axis and a transverse direction (Q) extending perpendicularly thereto. The cutting face (325) has a concave shape in the transverse direction. An effective width, measured in the transverse direction (Q), of the cutting face varies in the longitudinal direction (L) of the cutting face.
