Klingelnberg AG presents its latest innovation, skiving. This newly developed tool system can be used on bevel gear milling machines and allows for a productive, stable and precise production process, particularly for internal gears. Despite high productivity and system-inherent accuracy, the breakthrough of skiving has been denied due to the the tool problem. The chip formation process in skiving is very complex whereby large negative rake angles and only very small clearance angles arise during the process. The current tools, mostly cylindrical or conical solid carbide cutting wheels, have no degree of freedom for the necessary optimization. In addition to high machining forces, negative cutting angles also consistently lead to excessive wear of the tools meaning that the tool costs per component largely surpass the proportional machine costs. Klingelnberg’s newly developed software shows the exact chipping conditions and therefore allows for a targeted optimization of the cutting geometry and the production movement. The new stick blade tool system uses carbide technology which has long been used for bevel gears. Learn more at [www.klingelnberg.com].
