Abstract
The present disclosure comprises a gear manufacturing machine comprising a workpiece holder and a tool holder, which can each be caused to rotate by means of a drive, wherein the tool holder is arranged on a machining head, which can be moved relative to the workpiece holder by one or a plurality of motion axes of the gear manufacturing machine for gear manufacturing machining a workpiece held in the workpiece holder by means of a tool held in the tool holder, the tool holder having a counterholder. According to the present disclosure the counterholder is movable by a motion axis from its working position to an inactive position and/or is arranged on the machining head of the gear manufacturing machine in a releasably connectable manner.
Claims21
A method of manufacturing a first and a second workpiece by a gear manufacturing machine comprising a workpiece holder and a tool holder, which each are rotatable by a drive, wherein the tool holder is arranged on a machining head, which is movable relative to the workpiece holder by one or a plurality of motion axes of the gear manufacturing machine, the tool holder having a counterholder, wherein the method comprises:
- gear manufacturing machining a first workpiece held in the workpiece holder by a first tool held in the tool holder in a first machining mode, in which the first workpiece is machined by the first tool clamped on both of its sides between the tool holder and the counterholder by milling, and
- gear manufacturing machining a second workpiece held in the workpiece holder by a second tool held in the tool holder in a second machining mode, in which the second workpiece is machined by the second tool clamped only on one of its sides in the tool holder by skiving, the counterholder occupying an inactive position or being dismounted from the machining head, wherein at the inactive position of the counterholder, all elements of the counterholder and its support exhibit a predetermined clear distance to an axis of the tool holder.
A method of manufacturing a workpiece by a gear manufacturing machine comprising a workpiece holder and a tool holder, which each are rotatable by a drive, wherein the tool holder is arranged on a machining head, which is movable relative to the workpiece holder by one or a plurality of motion axes of the gear manufacturing machine, the tool holder having a counterholder, wherein the method comprises:
- gear manufacturing machining the workpiece held in the workpiece holder by a first tool held in the tool holder in a first machining step, in which the workpiece is machined by the first tool clamped on both of its sides between the tool holder and the counterholder by milling, and
- gear manufacturing machining the workpiece held in the workpiece holder by a second tool held in the tool holder in a second machining mode, in which the workpiece is machined by the second tool clamped only on one of its sides in the tool holder by skiving, the counterholder occupying an inactive position or being dismounted from the machining head, wherein at the inactive position of the counterholder, all elements of the counterholder and its support exhibit a predetermined clear distance to an axis of the tool holder.
