The high speed grinding (HSG) is a variety of grinding methods above the common cutting speed [9, 10]. Firstly, cutting speed for surface grinding is higher by rapid feed rate of the workpiece. The increase of the wheel speed is another technique, which is presented in the following paper.

The example in the diagram, figure 6, shows a comparison of bearings for a high speed internal grinding spindle. At a speed of 40,000 r/min the radial stiffness of a particular hybrid bearing has been reduced to 70 % of the static stiffness, while for a comparable bearing with steel balls the stiffness has been reduced to 61 %.

The HSG-2's revolutionary technology allows up to 60 km of track to be ground non-stop. It produces virtually no sparks or dust during the operation and effectively reduces the noise emitted by rail traffic by 3 to 10 decibels. To supplement to its purely rail-machining role, in the future the grinding train will also be a diagnostics vehicle.

Usually high speed grinders are also high end in price and performance. They usually have flat burr sets, and beefier motors. The flat burrs provide a more consistent grind with more surface area to grind with, and the higher RPMs grind the beans faster and give it less time for heat to be transferred: it's processed through the grinder before it gets affected by any …
