Advantages of using the Precision Frog Grinder


Accurate four-axis grinding

With accurate four-axis grinding, Pandrol’s Precision Frog Grinder ensures precise, repeatable results, no matter the operator’s skills and experience.


Easy setup

The grinder’s simple, two-part design allows for quick set-up and clearing, saving on track time.


Flexible grinding

The flexibility to change from a straight stone to a cup stone allows the operator to use one tool for grinding a complete maintenance program, including grinding out frog defects, blending out SSC and reprofiling frogs.


8’ base rails

The grinder’s versatility is enhanced by the availability of 8’ base rails for blending out surface defects over greater distances than the standard 4’ base rails allow.


Safe to use

Vibration and dust isolation contribute to safe working conditions and practices.


Easy to transport

The Precision Frog Grinder is compact in size, making it easy to transport and store.

Technical features of the Precision Frog Grinder


Precise engineered movement

The Precision Frog Grinder has been designed to allow for accurate, repeatable movement in any of the four axes.


Adjustable stone

The height and position of the stone can be adjusted within the base frame. In addition, the angle of the stone can be regulated for precise elevations and reprofiling.


Articulating base frame

The base frame can be fully adjusted and locked to the angle of any frog, using an easy reference line and precision adjustment.


Vibration and dust isolation

All vibration and grinding dust created while working on frogs is isolated from the operator.


Multiple grinding stones

The Precision Frog Grinder can be used with a straight stone for flange ways and rail sides, and a cup stone for precise grinding of the tops and sides of rails.


Compact size

The grinder and its base are compact in size, easing transportation and storage.
