Chamfer-Skiving: A Felsomat Development for Machine Chamfering

 

Efficient and Optimized Chamfering of Gears

The quality requirements for gears in an e-gear have increased due to the significantly higher motor speeds compared to combustion engines. The problem with shafts for electric motors is that there is less space available for the tool due to their more compact design.

For this very reason, we at Felsomat have developed the process of beveling with chamfer-skiving. With the machine chamfering process, “Chamfer-Skiving”, the machining of the bevel is divided between two tools.

Each tool is used for the sharp and blunt tooth edge, which enables the two chamfers to be machined separately. The result is a higher bevel quality with bevel angles that can be produced independently from one another. Furthermore, due to the working angle, shaft parts or gear wheels with interfering contours can be machined on the clamping device.

With the integration of the machine beveling in the 2-spindle milling machine (FHC80 / 180), cycle times and quality losses can be avoided, which would otherwise result in a separate work step requiring re-clamping.

Thanks to the two-spindle machining that is parallel to production, the workpiece can be milled on one spindle while the bevel is produced on the other. The workpiece spindles rotate freely, configurable in and out of the milling area. In this way, different process variants between hobbing and chamfering, depending on the gear finishing process, can be implemented in only one setting.

For example, a shaft is clamped and initially roughed. It then leaves the milling area and is chamfered before it changes back again. A second finishing cut can be made there or finish milling can take place.
