The invention relates to a moving system () for moving workpieces that are provided for gear cutting on a workpiece spindle () and have a workpiece axis of rotation, from a first position (A), taken up while they are being fed, into a third position (C) that differs from the first position by at least a smaller distance between the workpiece axis of rotation and the workpiece spindle axis, having a first movement unit () which moves a workpiece from the first position into a second position (B), different from the first and the third position, along a first movement path (AB), and a second movement unit () which moves the workpiece from the second position into the third position along a second movement path (BC), wherein the moving system is also designed to move machined workpieces back out of the third position and to hold and move more than one workpiece at the same time, wherein, while it is being moved on the first and on the second movement path, the workpiece is held by one and the same holding unit (') that directly holds the workpiece, without a movement caused by the second movement unit entailing a movement of the first movement unit.

Moving system and gear-cutting machine

The invention relates to a machine for the gear cutting machining of workpieces, in particular a gear shaping machine, comprising a spindle for holding a machining tool, and a drive by means of which the spindle can be rotationally driven about its spindle axis, and further comprising an arrangement. When said arrangement is actuated, a spindle rotation caused by the drive changes the axial relative position with respect to the spindle axis.

Machine for machining workpieces, corresponding arrangement and method for machining workpieces

The invention relates to a method for loading and unloading an internally toothed workpiece or a workpiece that is to be provided with internal toothing into/out of a clamping position, in which the workpiece, which is held by a retaining device, is brought into the clamping position by means of a conveying movement so that said workpiece, when clamped, has internal toothing cut by a gear cutting tool that occupies a cutting chamber and, after cutting, said workpiece, which is held by the retaining device, is returned from the clamping position in a return movement, wherein, prior to cutting, the retaining device is permitted to carry out an evasive movement that is different from the return movement/reverse conveying movement and that frees the cutting chamber, or the cutting chamber is already kept free of the retaining device as soon as the clamping position is reached.

Method of loading and unloading a workpiece with internal gearing, and loading and unloading device

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.

Method for machining a set of teeth, tool arrangement, and tooth-cutting machine

The invention concerns a method to generate and/or machine gear teeth on a workpiece, wherein the workpiece is subjected to a movement from a first location where the workpiece, while being held by a clamping device connected to a workpiece spindle, is brought into machining engagement with a first tool, to a second location where the work piece, while remaining in its clamped condition, is brought into machining engagement with a second tool, wherein prior to performing the movement, the connection between the clamping device and the workpiece spindle is released, and after the movement, the clamping device is connected to another workpiece spindle for the machining engagement with the second tool.

Method for producing and/or processing a gear and gear cutting machine

The invention concerns a method for the machining of the tooth edges between an axially facing surface and the tooth flanks of a gear with a machining tool that has a toothed contour. For the material-removing cutting operation, the machining tool, rotating about the axis of its toothed contour, is brought into rolling engagement with the toothed workpiece under a crossing angle different from zero between the rotary axes of the machining tool and the toothed workpiece.

Method for machining tooth edges and machining station designed for this purpose

The invention concerns a gear-cutting machine for the machining of gear teeth with a gear-cutting tool driven in rotary movement about its tool axis, further with an assembly that includes a tool holder for the gear-cutting tool and is rotatably mounted on a carrier, allowing the tool axis to be set in a desired orientation, with an actuator device through which the assembly can be set to a desired angular position, and with a locking device that allows the assembly to be secured against being dislodged from the set angular position. According to the invention, a protruding arm that is a functional element of the actuator device is coupled to the assembly through a non-rotatable connection.

Gear cutting machine and method for machining gear teeth

A method and a device for machining the tooth edges () developed between each end face () and the tooth flanks () of end-cut work wheels (). The axis of rotation () of the spindle that carries the machining tool () is displaced around an orthogonal swivel axis () relative to the tool axis of rotation so that the cutting directions are opposite to each other with respect to the work wheel () in the machining of the lower tooth edges () and the upper tooth edges ().

Method for machining the tooth edges of end-cut work wheels

A gear cutting machine wherein a chamfer/deburr device and tool are fastened to a fixed component of the gear cutting machine. In this way, it is possible to adjust the chamfering/deburring tool into the working position in a simple and dependable manner to remove the edges from a gear. The device preferably has a linear track as well as a pivot axis, which can position the tool into the optimum position for the chamfering and/or deburring of the gear.
