Rail maintenance is a process consisting of constant-pressure grinding resulting in a level of metal removal that is dependent on the characteristics and rotation speed of the grinding wheel, the applied pressure, and the feeding speed and angle between the grinding wheel and rail.
Corrective grinding is not an economical method, because it requires removing amount of metal on steel rail, and reducing the working life by costing too much grinding processing. But, for ensuring steel rail have more longer useful life, corrective grinding is very necessary, especially in the time of tough budge.
Advanced Rail Management Corp. is a consulting/service company specializing in assessing rail and wheel conditions and designing and supervising rail grinding and wheel truing programs on freight, passenger and rail transit systems.
Rail Grinding is an important track maintenance tool Rail Grinding is the removal of metal from the surface of the rail head Through the action of a rotating grinding wheel Mechanism used in rail grinding is cutting of metal associated with formation of metal chips (and not metal deformation)

SERVICES We use our unique milling and grinding process for the machining of the rail. In only one pass, the rail head is reprofiled. The machining is done by peripheral milling with combined circumferential grinding. Advantages Clean Technology Our milling and grinding technology enables us to deliver a rail service...
Rail grinding is a process that is done to stop the deformation due to use and friction on railroad tracks by removing deformations and corrosion. Railroad tracks that experience continual use are more likely to experience corrugation and overall wear.
The article will discuss the use of rail grinding in the maintenance of track. A well planned and managed grinding process can result in longer rail life and reduce life cycle costs. In order to minimize costs and maximum benefits of rail grinding it is necessary to have a total rail grinding ...

Because of the respective contours of rail and grinding stone, the contact line between the two is ... 0.004'' (0.1 mm), which can be achieved with three grinding passes. The process has in 2007 been approved for operation on DB's High Speed network. It is the first maintenance ...
The rail grinder RRGM 0-16 is a rail-road going machine. The machine has 16 grinding spindles with independent angular adjustment. They are driven by frequency-controlled electrical 7,5 to 15 kW motors.
Linsinger says its rail milling technology combines rail milling and grinding in a single operation with a high degree of accuracy and performance, adding that light rail systems can achieve a significant reduction in maintenance costs by use of this technology.
Optimizing the grinding process and continuing to develop the rail profile are all possible steps to further increase rail life. Neither grinding campaigns nor objective measurements to increase wheel life using a new rail profile, seems to negatively affect the total wheel/rail system.
Rail grinders were developed to increase the lifespan of the tracks being serviced for rail corrugation. Rail grinding is a process that is done to stop the deformation due to use and friction on railroad tracks by removing deformations and corrosion.
1348_ROGRIND_Rail_Head_Profile_Grinding_Machine_en.pdf How does ROGRIND Head 1.0 improve ergonomics while grinding? The entire machine has been designed with a view to ergonomics: The outrigger keeps the frame upright on the track and the operator retains their natural posture for the entire grinding process.
Rail grinding is a key maintenance activity for Network Rail. It is performed at night through possession of the track, so process speed is critical. Increasing the metal removal rate (MRR) of the rail grinding operations would be a way to improve the …

Rail milling is a good process to use in tunnels as the milling process is clean and the reduced amount of grinding sparks minimises the risk of fires. This ability was put to good use at Heathrow on infrastructure managed by Network Rail's Reading delivery unit.
By Dr. Wolfgang Schoech • July, 2007. Rail grinding practices and requirements have evolved over the years. In the past, rail grinding programs were controlled by railway personnel who were responsible for selecting the sites, choosing the number of grinding passes and determining when a program was finished.

During the grinding of new rails, which should be performed before putting the rails into service or as soon as possible thereafter, the differences in the surface structure (low-carbon and high-carbon areas) caused by milling in the rail production process are eliminated by removing the upper surface-decarburized layer.

The rail milling & rail grinding process is a gentle material treatment and keeps the metallurgical structure of the rail steel untouched (no blueing, all heat is transferred to the removed chips). It can be used also in switches, crossings and especially in tunnels as it is free of dust.
