Abstract

The invention relates to a high-speed train grinding wheel and a preparation method thereof, and belongs to the technical field of manufacturing of abrasive and grinding tools. The preparation methodof the high-speed train grinding wheel comprises the following steps of burdening, distributing, brazing and sintering, reaming, paint spraying, edge cutting and correcting of dynamic balance. The brazing sintering is carried out at the temperature 1000-1090 DEG C under a vacuum condition, the adopted alloy powder brazing filler metal comprises, 31-35 wt% of Ni, 23-25 wt% of Mn, 1.25-2.5 wt% of Si, 0.30-1.0 wt% of B, 1.0-1.5 wt% of Fe, 1.0-5.0 wt% of Cr, and the balance Cu, and the abrasives are composite abrasives of diamond particles and silicon carbide. The alloy powder brazing filler metaladopted by the high-speed train grinding wheel does not contain rare metal W, Co and precious metal components, so that the cost is low, the brazing sintering temperature is low, the thermal damage of the diamond particles is small, the wettability is good, the thermal expansion coefficient is low, a good holding force can be formed for the abrasive compound, the grinding effect of the abrasivescan be fully exerted, and the service life is remarkably prolonged.

Description

technical field [0001] The invention relates to the technical field of manufacturing abrasives, more specifically, the invention relates to a high-speed iron grinding wheel and a preparation method thereof. Background technique [0002] The Tokaido Shinkansen railway system built and operated in Japan in 1964 is the world's first commercial high-speed railway (referred to as high-speed railway) that can truly allow high-speed trains to run safely and stably for a long time. Subsequently, France, Italy, and Germany built high-speed railways one after another. On August 1, 2008, the Beijing-Tianjin intercity high-speed railway with a speed of 350 kilometers per hour was put into operation, creating a new era of high-speed railway in my country. [0003] In order to ensure the smoothness, stability and safety of high-speed rail lines, many track systems of my country's high-speed rail adopt the ballastless track system developed by Deutsche Bahn. In the ballastless track syste...
