The invention relates to a method and a device for finishing toothed workpieces (2) using a tool (1) which is designed in the form of a power skiving cut-ter and is rotated by a tool spindle (17) and which has machining teeth (7) that mesh with tooth gaps (6) of the workpiece (2) in a rolling movement, said workpiece being supported by a workpiece spindle (15), which is arranged in a skewed manner relative to the tool rotational axis (4) and is driven synchronously thereto, such that machining edges (8) of the machining teeth (7) machine the tooth flanks (9) of the teeth (5) of the workpiece (2) in the direction of the tooth flank extension. According to the invention, the tool is used such that the machining edges (8) machine the tooth flanks (9) so as to only grind same without removing chips, wherein for this purpose the rounding radius of the machining edges (8) is greater than the chip thickness or cutting depth (E).

A cutting tip, a cutting tool and a gear edge cut-off device have greater ease-of-use than the conventional art. The cutting tip has a shaft portion supported linearly movably and forwardly biased in a linearly moving direction, an angular base portion provided at a front end of the shaft portion and having a pair of skirt faces and a ridge portion that extends obliquely with respect to the linearly moving direction, a groove depressed near the ridge portion of the skirt face, a blade edge on the cutting blade, positioned on a border line between the ridge portion and the groove, a rake face provided on the cutting blade and positioned further toward the groove side than the blade edge, and a flank face positioned further toward the ridge portion side than the blade edge and jutting out in the forward direction as it retracts from the blade edge.

The invention relates to a method for machining a toothing, wherein to form a chamfer on a tooth edge formed between an end face of the toothing and a tooth flank belonging to a tooth space of the toothing, material is removed from the tooth edge by cutting, by means of a machining tool equipped with a cutting edge, in a machining operation, wherein the machining tool is toothed and the machining operation is a skiving machining operation at an axis intersection angle between the rotational axes of the machining tool and the toothing, which does not extend beyond the tooth root section of the tooth space

An object is to provide a gear edge cut-off tool and a gear edge cut-off device capable of suppressing variation in the amount to cut off side edges of a gear. A gear edge cut-off tool of the present invention has a shape, in a first main plane (rake face) of a first cutting blade portion capable of cutting off a side edge of a gear wheel, that is curved or bent in a concave shape in an edge line direction.

A method for producing a toothed workpiece wheel, the tooth root of which adjoins an end face of the workpiece wheel with a chamfer extending into the tooth flanks being formed, wherein the toothing of the workpiece wheel is created by skiving with a gear-cutting tool which has a first number of cutting teeth that each form cutting edges and the rotation axis of which is at a first crossed-axes angle to the axis of rotation of the workpiece wheel, with an infeed in a first infeed direction parallel to the direction of extension of the tooth flanks to be produced and of the tooth root. The chamfer is created by skiving with a chamfering tool which has a second number of cutting teeth that each form cutting edges and the rotation axis of which is at a second crossed-axes angle to the axis of the workpiece wheel, with an infeed in a second infeed direction parallel to the direction of extension of the chamfer to be produced in the tooth root. Also disclosed is an associated tool set.
