The present invention shows an apparatus for a chamfer machining of a toothed workpiece comprising a workpiece spindle having a workpiece holder rotatably supported about an axis of rotation for holding the workpiece, a tool spindle having a tool holder rotatably supported about an axis of rotation for holding a finger mill, wherein the tool spindle is travelable relative to the workpiece holder via at least one linear axis of the apparatus, and a control having a machining function that rotates the workpiece held in the workpiece holder by controlling the workpiece spindle for the chamfer machining of a toothed workpiece while a finger mill held in the tool holder engages at the edge to be machined. It is characterized in that the machining function varies the rotational speed of the workpiece during the chamfer machining.

Apparatus for a chamfer machining of a workpiece

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.

Gear manufacturing machine

The present application relates an apparatus for chamfer-machining at least two edges of a toothed workpiece, wherein the apparatus comprises at least one workpiece spindle with a rotatably mounted workpiece holder for receiving the workpiece and a machining head movable relative to the workpiece holder via at least one axis of movement, wherein on the machining head at least one first tool spindle with a first rotatably mounted tool holder is provided for receiving at least one first chamfer milling cutter for chamfer-machining a first edge of a toothing of a workpiece received in the workpiece holder, wherein on the machining head a second tool spindle with a second rotatably mounted tool holder is provided for receiving an end milling cutter for chamfer-machining a second edge of a toothing of a workpiece received in the workpiece holder.

Apparatus for chamfer-machining a workpiece

The present disclosure relates to a method for the gear manufacturing machining of a workpiece in which a hobbing machining of the workpiece takes place to generate a gearing geometry of the workpiece, wherein the workpiece is gear manufacturing machined by gear skiving in addition to the hobbing machining.

Method for the gear manufacturing machining of a workpiece

The present disclosure relates to an apparatus for chamfering at least one edge of the gearing at the front side of a workpiece having internal gearing comprising at least one rotatably supported workpiece holder for holding the workpiece and comprising at least one rotatably supported tool holder for holding at least one chamfer hob, possibly a chamfer cut hob, wherein the tool holder is arranged and/or arrangeable next to a workpiece held in the workpiece holder and a chamfer hob held in the tool holder is arrangeable by means of a tool arbor in the region of the center opening of the workpiece formed by the internal gearing to be brought into engagement with an edge of the internal gearing on the upper side and/or on the lower side of the workpiece.

Apparatus and method for chamfering a workpiece having internal gearing

The present disclosure relates to an apparatus for chamfering at least one edge of the gearing at the front side of a workpiece having internal gearing comprising at least one rotatably supported workpiece holder for holding the workpiece and comprising at least one rotatably supported tool holder for holding a chamfer hob, possibly a chamfer cut hob, wherein the tool holder is arranged at an internal hob arm whose free end can be traveled by a machine axis of the apparatus at least partly into the center opening formed by the internal gearing of the workpiece.

Apparatus and method for chamfering a workpiece with internal gearing

This present disclosure relates to a device for rotary entrainment of a workpiece clamped between two tips, which is mounted on a machine table of a machine tool, consisting of a base body with a centrically arranged tip and a plurality of concentrically arranged, axially shiftable driver elements which for the rotary entrainment of the workpiece are pressed against or into an end-face surface, wherein an axial position of the driver elements can be defined by active fixation after a centering operation of the workpiece, and to a receptacle opposite the base body, for example a tip or hollow tip, which serves a guidance of an opposite side of the workpiece.
