Understanding Why, When and How Rail Grinding is Performed

Profile Grinding Goals • Top of rail should never have a radius less than 8” – Reduced running band can result in high stresses and rail surface fatigue (spalling) – Running band should be between 1 1/4 and 1‐3/4 inch on all rails • Reduce plastic deformation and metal surface fatigue

Target Profiles for Rail Grinding: A Never Ending Story ...

Jan 04, 2014  Rail maintenance work is a process of removing metal from the rail head at the right time and at the right place. At first, rail grinding was performed to remove surface irregularities and defects — a process that required significant metal removal. During this curative process, the transverse rail profile was of secondary importance.

Railgrinder - Wikipedia

A railgrinder is a maintenance of way vehicle or train used to restore the profile and remove irregularities from worn tracks to extend its life and to improve the ride of trains using the track. 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. Railroad

Guide Rails Thomson Thomson

Square guide rails are well suited to high-load applications that require good rigidity and high accuracy. These linear guide rails achieve their performance through the precise grinding of the ball tracks in the rail, which have close conformity to the balls. The classic application for profile rail bearings is in the machine tool industry, where load capacity, rigidity and accuracy are paramount.
