Rails and points

 Setting the course for perfect machining

The primary objective when manufacturing Vignole or transition profiles and points is always ensuring a long service life. At the same time, rails and points are exposed to heavy loads on a daily basis. With tensile strengths of between 700 and 1600 N/mm2, the rail steel used presents a real challenge for machining. The requirement here is for tough tools which can be used flexibly in a very wide range of conditions. The powerful Walter milling tools are ideal in such circumstances. They are available for all current rail profiles and pitches and provide a high degree of process reliability and productivity, whatever type of material is used.

Multi-axis turn/mill centres and vertical turret lathes are primarily used for machining these materials. Walter tools for turning, milling, drilling and threading enable you to machine engine housings with maximum efficiency, precision and process reliability
