Abstract
A method of surface grinding a Zr-rich bulk amorphous alloy article includes providing a substrate; providing a first surface grinder for rough surface grinding; and providing a second surface grinder for finish surface grinding. During the rough surface grinding, the rotating speed is in the range from 20 r/min to 30 r/min, the grinding time period is from 3 minutes to 12 minutes, and the grinding pressure is from 1 kg/cm2 to 2 kg/cm2, and a first pump circularly conveys a first lubricant to a first rotating abrasive wheel. During the finish surface grinding, the rotating speed is in the range from 30 r/min to 40 r/min, the grinding time period is from 5 minutes to 7 minutes, and the grinding pressure is from 1 kg/cm2 to 2 kg/cm2, and a second pump circularly conveys a second lubricant to a second rotating abrasive wheel.
