rail profile milling

Milling of three different rail profiles OEM UPDATE

One of these projects includes the milling of three different rail profiles for a customer in the Netherlands. Dormer Pramet’s 600mm diameter dynamic rail milling cutter was able to machine the combined profile (60E1, 54E1, 46E3 1:40) and another profile 54E5 1:40, without having to change the inserts.

Railhead Damage: Rail milling issues

6.3 Rail milling issues. When a rail is milled, the milling cutters have been pre-set to establish a specified transverse profile. It is therefore both more difficult than with other reprofiling techniques to vary the profile and also more difficult to establish an “incorrect” profile, unless the specified profile

smooth surface finish of the target rail profile. The process speed of rail milling may vary between 1312 ft/h (400 m/h) up to 6560 ft/h (2000 m/h) of finished/maintained rail (dependent on machine type). Besides, a milling machine can process main track as well as special trackwork like switches and crossings. No dedicated switch-milling

SF03 W-FFS Rail-Milling Train Vossloh

Depending on the rail's condition and the defect depth, this rail-milling train manufactured by Linsinger can machine the rail's entire profile in only a single pass. The integrated grinding technology also fine-grinds the rail, and in so doing further extends the rail's service life. The SF03 W-FFS can operate independently for up to 8 hours

Analysis of rail milling as a rail maintenance process

2019-11-15 · The milling tool is modeled as a rigid body, and for the material description of the rail head an elastic-plastic behavior is used. For both parts, the rail and the tool holder, tetrahedral elements with a higher element density at the top surface of the rail head and the insert area of the tool holder are taken to model the chip formation process accurately.

Superheroes of Rail Railway Age

Main line rail milling machines are equipped with multiple tools per rail, allowing a profile change on the fly.” As well, the passing speed is slower compared to other maintenance technology, “which can be something between 400m an hour up to 2km an hour, depending on machine size and how much and what you need to do,” Stock says.

Milling Rail Care Solutions

Fundamental rail defects, cracks or extreme deviations from the target profile have far-reaching, negative effects on track service life, ride comfort and safety and are consequently reflected in the service life cycle costs of the tracks and their components. In these cases, appropriate milling technology is recommended in order to
