Schaeffler relies on DMG Mori machines for additive manufacturing

In their latest cooperation, Schaeffler (Herzogenaurach, Germany) and DMG Mori (Bielefeld, Germany) are developing additive manufacturing processes for rolling bearing components made of graded materials in small batch sizes using laser deposition welding. Schaeffler is expanding its in-house additive manufacturing area to include the powder-nozzle LASERTEC 65 3D hybrid system from DMG Mori for producing components made of metallic materials. The high build-up rate and high degree of flexibility of materials were aspects that significantly influenced the decision. In addition, integrated five-axis simultaneous machining enables production of components in finished part quality in a single setup, a feature in which Schaeffer sees potential for serial production.

The LASERTEC 65 3D hybrid system is equipped with two powder feeders, and enables targeted control of the changeover from one material to another during laser deposition welding. This results in graded materials with a smooth transition between the different material properties. The toughness and hardness of the material can be regulated in the build-up process and optimally aligned to the specific requirements of the individual application.

The two companies are testing suitable materials with the aim of advancing the development of additively manufactured rolling bearing components in small batch sizes using laser deposition welding. Schaeffer's focus of attention here is on attaining optimized products that offer added value for end customers.
