Zusammenfassung:The present disclosure provides improved rail grinding tools. Precision-shaped grains (PSGs), such as PSGs manufactured by 3M® company, provide significant performance improvement in resin-bond and vitrified bond grinding wheels. The use of PSG improves the performance of portable bonded wheels and precision grinding wheels, such as resin bond roll grinding wheels, flute grinding wheels, vitrified gear grinding wheels, cylindrical grinding wheels, and surface grinding wheels. The formation and composition of (e.g., monolithic) and multiple-layer PSG grinding tools described herein provides improved performance of rail grinding tools.
