Wheel cutting machine
A wheel cutting machine is a device that is used to manufacture clockwork wheels in one-off production.
history
In 1885 two entrepreneurs, Johann Morat and Josef Koepfer , developed the first serial wheel cutting machines . As the need for different, small gears increased with each new generation of clocks , mechanical devices were required to complement the fine craftsmanship of the clockmaker . For this purpose, among other things, cutting chairs were developed - powered by human or water power - with which gap by gap were filed into the gear wheel according to the dimensions of a graduated disk. Not infrequently, new industries for mechanical engineering and the mass production of gears developed out of demand. One of them was the first mass-produced wheel cutting machine.
description
A dividing disc with numerous circles forms the core of the wheel cutting machine. The circles contain cone-shaped holes that are evenly spaced. The number depends on the number of gear teeth commonly used in watchmaking. The machine is set using an angle arm, the tip of which is inserted into the graduated disk holes. As soon as the tip moves one hole further, the wheel to be machined is turned further accordingly. In this way, a shaped milling cutter mills gaps in the wheel rim one after the other, which correspond to the walls of the wheel teeth.
