Problems solved by technology

[0010] Disadvantages of the tool systems available so far include: Changes in the contour geometry of the user's workpiece that cannot be achieved by rotation or selective infeed when dressing the grinding worm can only be produced by so-called wire dressing
However, this method involves the disadvantage that the linear pre-shaping, finishing and post-shaping of cylindrical grinding worms is very time-consuming due to the many individual shaping steps and is only partially suitable for grinding on specialized machines. cut repetitive batches

Embodiment Construction

[0063] Such as figure 1 The general construction of the gear grinding machine shown has already been described above in relation to the prior art. Such a gear grinding machine is now also used to carry out the method according to the invention, wherein the control of the gear grinding machine is advantageously designed to carry out the method, in particular the control comprises corresponding operating modes as well as corresponding operator prompts.

[0064] Next, two embodiments of dressing a profile tool on such a gear grinding machine according to the invention will be described.

[0065] In a first embodiment of the method according to the invention for dressing a profile tool on a gear grinding machine, a rotationally symmetrical profile tool with a multi-layer coating of hard material is clamped on the grinding head of the gear grinding machine - i.e. the work spindle 5 and is driven around axis B1. The speed and direction of rotation can be selectively controlled by ...

Abstract

The present invention relates to a method for operating a gear grinding machine, with the following operating phases of the gear grinding machine: machining a workpiece on the gear grinding machine by means of a grinding disk and / or grinding worm and dressing a profiling tool for profiling a grinding disk and / or grinding worm on the gear grinding machine.

Description

technical field [0001] The invention relates to a method for operating a gear grinding machine. Such gear grinding machines are used for machining workpieces on the gear grinding machine by means of grinding discs and / or grinding worms. Background technique [0002] In the production of gears, gear grinding machines are used for the fine grinding of pre-machined gears so that the gears are brought into their final geometry. In the production of gears, usually, the teeth are first formed from a rotationally symmetrical workpiece in a soft pre-machining step, such as milling or slotting. Subsequently, the workpiece premachined in this way is subjected to a heat treatment, by which at least the region of the gear wheel lying close to the tooth surface is hardened. In order to compensate for changes in the surface geometry produced during the heat treatment, and to machine the surface geometry of the tooth with greater precision, fine grinding is therefore carried out on a gea...
