High performance milling uses Vossloh’s newly developed milling train VTM-performance, which is equipped with groundbreaking technology that is quicker, more precise and better for the environment than conventional milling systems. A single pass performs the following machining sequence: peripheral milling and face milling (finishing) with simultaneous verification of the rail’s machined condition.
In the VTM-performance, the 1,400 mm diameter milling wheel is more than twice the size of a standard milling wheel, which ensures less residual ripple after machining, a very high-quality surface, faster operating speeds and a higher material removal rate. All the metal removed is extracted into a bunker, and the encapsulation of the milling units ensures that nothing is left behind. The fully integrated finishing employs a new kind of face-milling technology that renders a final grind unnecessary and ensures that the procedure is free of grinding dust or sparks.
At the customer’s request, on-board measuring equipment can be integrated in advance to check the quality and safety of the reprofiled rails immediately after machining.
