Rail grinding is an essential part of maintaining healthy rail conditions by improving the rail profile after excessive wear. ABOVE Rail grinding is hard work, and serious business. Properly profiled rail can save a railroad lots of money by extending the rail life and reducing wear to other track components.
Nov 18, 2020 A grinding machine uses an abrasive wheel as a cutting tool to shape or change the dimensions of a hard material. The type of materials that need grinding are usually metallic items such as tools and rods. These machines generally work by reducing the material through abrasion. Generally, the grain of the abrasive wheel chips away at the.

Grinding machines. Portable grinding and deburring machines are widely used to restore an accurately shaped rail head, during reprofiling of flat bottomed and grooved rails after welding work on the rail, they are also ideal for deburring the rails. The different models are described in the following sections. Reprofiling and grinding machines.
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. Rail life is extended and rail Life Cycle Costs (LCC) are decreased.
