In an apparatus for the cutting, deburring or breaking of the side tooth edges of gears with one or two tools which are located on the side of a guide gear and which machine the aforesaid tooth edges. The guide gear meshes with the workpiece, and, in one embodiment, is constructed as a measuring gear. Prior to the actual machining operation, the distance between the axes of the pretoothed workpiece and the measuring gear is measured independently and is made visible, if desired, on an indicating device. In order to avoid incorrect measurement results due to burrs existing on the workpiece, the guide gear can, if desired, have recesses into which extend the burrs.

Gear deburring apparatus and method

A mandrel for receiving the tool of a tool machine which has cones on both ends thereof for centering the mandrel in a tool machine spindle. Securing structure is provided for securing the mandrel to the tool machine spindle so that rotational drive is provided therefor. A stop is provided on one end of the mandrel intermediate the two cones and a cylinder-like device is provided at the end remote therefrom but also spaced inwardly from the cones. A piston is reciprocably mounted in the cylinder and engages a tool mounted on the mandrel. An application of pressure to the cylinder will cause an axial movement of the piston to engage the tool to effect a clamping of the tool between the stop and the aforementioned piston.
