Mobile rail grinding functions primarily on the basis of the oscillating movement of the grinding units and secondly due to the continuous forward travel of the machine. the grinding stones adapt to the rail crosssection. rail planing reprofiles the rail head without having to remove the rail. to achieve this, various planing tools are applied.

Ngm4.4ii internal combustion rail grinding machine manufacturers , its suitable for grinding rail welding seam, uneven joint, rail side fat edge, rail surface repair welding of rail 43kgm75kgm. its grinding quality is good and its easy and simple to handle, and convenient to be up on and down from the rail. its an indispensable tool for railway engineering heavy repair.

Nm180 rail tools disc portable railway grinding machine structure: nm180b is combined with engine, clutch, spindle, output shaft. working principle: engine outputs energy through the centrifugal clutch to the spindle by 7000±500 rpm, the engine pass the varea and vwheel by1:1 to the output shaft, making the grinding wheel produce a 80ms linear speed for grinding operation.

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 14 and 1‐34 inch on all rails • reduce plastic deformation and metal surface fatigue.

Rail grinding grinding tools for grinding of flat bottom and grooved rails with grinding wheels. grinding of flat bottom and grooved rails with cup wheels. grinding of the rail head with grinding blocks cuttingoff of flat bottom and grooved rails, grinding of the running table with linsinger milling and grinding machine, grinding of the running table with high speed grinding.

Rail grinding is the cornerstone of virtually every railroad maintenance program. to maximize the life and value of rail assets, precision removal of fatigued metal, restoration of the rail head profile and removal of rail defects are the optimization goals of an effective rail grinding program.

Rail grinding is used to restore the track head profile and remove corrugations. such grinding extends the rail life, improves the ride quality of trains, and reduces noise. the current regime involves hire of the rail grinding machine and reprofiling 300m and 600m radius sections after 30 million gross tons (mgt) of traffic running over them.
