Hob peeling tool and method for hard-fine machining of pre-toothed workpieces

A method for fine machining a workpiece having pre-machined teeth by hob peeling, the method comprising:

• rotating a workpiece about a workpiece axis;
• rotating a tool about a tool axis in a rolling engagement with the workpiece, the tool in relation to the workpiece axis being aligned in a skewed manner, wherein the rolling engagement defines a rolling angle;
• wherein the tool is fed axially in a direction that is parallel or antiparallel with the workpiece axis;
• wherein the tool comprises a gear-wheel shaped main body which defines a tool axis and which on an end face defines a tip circle, and one or a plurality of cutting inserts which are disposed on the main body at the end face in the region of the tip circle, wherein each of the cutting inserts comprises at least one cutting tooth, the cutting tooth forming a cutting edge which runs at least along one flank of the cutting tooth from a tooth tip to a tooth base of the cutting tooth, and wherein the cutting tooth has a cutting face associated with the cutting edge, and a clearance face associated with the cutting edge;
• wherein the cutting face of each cutting tooth along the cutting edge has a cutting face chamfer which in relation to the cutting face is inclined by a chamfer angle, wherein the chamfer angle varies along the cutting edge;
• and
• wherein the cutting face chamfer is configured such that chips which form during the passage of the cutting edge through a tooth gap of the workpiece run off exclusively by way of the cutting face chamfer, the cutting face acting only as a reference face.
