Rail Joint Grinding

Rail joint grinding after welding

This requires a specialized grinding wheel composition, where Hioma has developed a single quality that can be used for both pre-grinding of the red glowing hot weld, as well as for cold fine grinding of the joint to the definite profile. Therefore, there is no need to change the grinding wheel between the two grinding phases.

Hioma grinding wheel qualities in use for grinding alumothermic welds as well as flash butt welds are commonly adjusted to a variety of customer requirements in local markets.

Corrective rail joint grinding

Over time, rail joints can develop irregularities due to wear and tear, leading to points of impact, which can cause damage to the rail and rolling stock, and affect the smoothness of train travel. Grinding removes the impact forces at the joints.

Joint grinding equipment

Smaller portable manually operated grinders are used for spot grinding and maintenance tasks of limited length. Hioma produces grinding wheels that can be attached to most manually operated rail maintenance grinders as well as bigger grinding vehicles.
