A tool for generating tooth systems by grinding when the maximum tool diameter is limited by collision contours on the workpiece has a dressable grinding tool that is tightly connected to the tool holder. In one preferred arrangement, the dressable grinding tool is glued on the tool holder.

Tool for grinding toothed workpieces having collision contours

The present disclosure relates to an apparatus and to a method for dressing generating grinding tools or profile grinding tools for the gear cutting processing of toothed workpieces using at least two disk-shaped dressing tools with which one or more tool regions and/or profile regions of the tool are provided with a defined dressing geometry.

Double-side dresser

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.

Method for operating a gear grinding machine

This invention relates to an apparatus for the prototype and small-batch production of gear wheels with a dressing disk. In accordance with the invention, the dressing disk has an asymmetric flank shape and a defined head radius. Furthermore, this invention relates to a method for the prototype and small-batch production of gear wheels by using such dressing disk.
