Wheel set

 Wheel machining in detail

A wheel set for a modern rail vehicle consists of two monoblock wheels and one axle. These vehicle components are important for vehicle safety and must be able to withstand enormous physical and thermal stresses. The demands on material and manufacturing process are accordingly high. Forged steel (tensile strength 800 to 1000 Nm/mm2) needs to be machined with a high degree of precision.

This is because the surface quality has a direct influence on the running characteristics and, consequently, on energy efficiency. Walter turning tools are made for such challenges and provide the user with an extremely high level of precision, reliability and flexibility in one cost-effective machining process.
