The differential gear ring is made of hardened steel with an inner layer of automatically assembled motor vehicle differential gear ring parts. In the turning process, the key to the production and processing challenge lies in the continuous turning process. The surface quality and dimensional tolerances must be in accordance with customer specifications and the use of high-end customised combination tools such as turning inserts, alloy drills and reamers is essential for the production process.

Highly efficient, safe and reliable turning of internal diameters and faces with low cost and time, ensuring high productivity in external and face turning, rapid, high quality and stable mass production of bores, accurate boring for the highest surface quality and efficient turning of internal diameters and backs.
