ROMILL SYSTEM

The complete solution for modern rail maintenance

YOUR TASK.
OUR CHALLENGE.

An increase in passenger numbers, higher speeds, freight traffic with high volumes of freight as well as high route utilization put huge stresses on rails and switches and accelerate the process of wear. This results in rail defects such as cracks and deformation. They in turn lead to a shorter service life of the rails, contribute to more noise, reduce the ride comfort, and also present a significant safety risk.

MAXIMISING THE SERVICE LIFE
OF THE RAIL

During corrective rail treatment, advanced defects are removed in one pass with a high material removal rate to restore the target profile of the rail.

ROMILL removes rail defects and reduces:

  • Safety risks
  • Delays and idle times
  • Rail and wheel wear
  • Life cycle costs
  • Noise pollution
  • Rolling friction

ROBEL RAIL TREATMENT

In order to meet the growing demands on rail systems and minimise the associated costs and risks, a sustainable and efficient solution for rail maintenance is required. ROBEL's rail treatment systems combine state-of-the-art milling, grinding and measurement technologies to restore the rail profile. In just one pass, rail defects are measured and removed, the rail profile is corrected and the results are documented. This treatment optimises wheel-rail contact and increases the service life of the rails. Our comprehensive worldwide service allows us to support customers on site during the entire maintenance process and beyond.

THE COMPLETE SOLUTION

  • Milling technology for defect removal and reprofiling
  • Grinding technologies for smooth surface finishing
  • Measurement technologies for recording the rail condition and documenting treatment results

MILLING TECHNOLOGY

PRECISE. SUSTAINABLE. SAFE.

Milling technology is characterised by incredibly precise guidance on the track, which enables the highest precision even under difficult conditions and results in the efficient elimination of rail defects. The interaction of technological solutions, the smallest manufacturing tolerances and the selection of high-quality materials form the basis for the treatment results. For a defect-free rail with the lowest transverse and longitudinal profile tolerances.

WHY RAIL MILLING?

Complete elimnation of rail defects and reprofiling in a single pass

  • Variable material removal of up to 2 mm per pass, per milling wheel from the top edge of the rail
  • Repeatable, precise production of the defined target rail profile

No sparks, no dust and no heating of the rail during the milling process

  • Increased safety
  • No fire hazard
  • No damage to infrastructure

Environmentally friendly and sustainable

  • Removed material 100% recyclable

ADVANTAGES OF ROBEL MILLING TECHNOLOGY

PENDULUM TECHNOLOGY

  • Vertically restricted guidance of the milling wheel for precise and safe working
  • Optimum results even in difficult track positions

MILLING WHEEL SEGMENTATION

  • Segment exchange replaces exchange of the entire milling wheel
  • Increased safety and ergonomics due to reduced lifting loads
  • High flexibility due to quick changeover of cutting tools and transition to new target profiles
  • Damaged cutting tools can be replaced individually

TOOL POSITIONING

  • High density of cutting tools due to upright positioning in the milling cassettes
  • Continuous force application leads to increased service life of the cutting tools
  • Optimum treatment results due to the high number of cutting edges

FINISHING TECHNOLOGY

PROVEN. CLEAN. POWERFUL.

Rail milling creates a characteristic rippled structure on the rail surface, which leads to temporary noise effects (a high-pitched "singing" sound) as a result of resonance, due to its periodicity. The ROBEL finishing technology smoothes this structure and ensures a standard-compliant, longitudinally oriented surface of the rail head with surface quality according to EN 13231-2:2020.

OSCILLATING GRINDING

Decades of proven rail grinding technology for tracks with particularly high requirements in the area of noise and vibration.

  • Treatment of the entire rail head
  • Minimal dust emissions
  • 100% spark-free

HIGH PERFORMANCE POLISHING

A new and powerful process to produce ideal surface finishes.

  • High machining speed
  • Treatment of the contact band
  • High-performance extraction for minimal flying sparks

MEASUREMENT TECHNOLOGIES

USER-FRIENDLY. ACCURATE. FLEXIBLE.

The ROBEL Group supplies the appropriate measuring equipment to determine the condition of the rail and document the processing results. In addition to measuring the transverse and longitudinal profile of the rail, cracks in the rail surface can also be detected using eddy currents. Specific software packages are available for each application, for the evaluation, documentation and subsequent archiving of the measurements.

LONGITUDINAL PROFILE MEASUREMENT

Contact-based measuring system for measuring the rail surface in the wavelength range of 10 -1000mm.

RAIL DEFECT MEASUREMENT

Variable, adjustable, sensor-based measuring system for the detection of rail defects in the rail surface by means of an eddy current.

CROSS PROFILE MEASUREMENT

Laser-based measuring system for measuring the rail head and the wear reserve both pre- and post-treatment.
