When extremely high strength is required, for example in high-speed operations (>100 meter per second surface speed), then the resin may be further reinforce with glass fiber. There are limitations, however, in terms of temperature that can be permitted at grinding/cutting surface. Also, resins wheels can be attacked by alkaline grinding fluids.

combined cutter blades [14], and the high-speed grinding by non-driven abrasive wheel [15]. They all have obtained much success in their own specific fields and have reflected different development tendencies of the rail grinding technology towards intellectualization, high efficiency, high quality, diversification, and greenization.
