Provided is a grinding method of the surface of a high-grade stainless steel frosted plate. The steps of grinding method include that, (1) throwing pills, firstly, after a steel plate is annealed, cooled and scale broken, the steel plate is taken into a pill throwing machine, new steel pills are stopped from being added at the time of five hours earlier of the steel plate being taken into the pill throwing machine, then, when narrow materials throws pills, throwing head speed is 1850-2000 revolutions per minute, and when broad materials throws pills, throwing head speed is 1600-1700 revolutions per minute, (2) rolling overall pressure rate of a cold rolling being equals to or over 65%, (3) starting a first upper grinding head, a second upper grinding head and a third grinding head in the grinding time, firstly, the grain size of a abrasive band is polished, the new abrasive band is firstly ground to be attenuated on other steel coils, an abrasive band of the attenuation equal to or over 100 minutes and an abrasive band of the attenuation equals to or over 200 minutes, secondly, the abrasive band of the attenuation which equals to or over 100 minutes is mounted on the first upper grinding head, and then two abrasive bands of the attenuation equal to or over 200 minutes are installed on the second upper grinding head and the third grinding head to be precisely ground. The grinding method improves the surface quality of the frosted plate of the cold rolling and reduces the surface defects of the steel plate.
