Abstract:
1. A method of surface grinding Zr-rich bulk amorphous alloy article, comprising: providing a substrate made of Zr-rich bulk amorphous alloy; providing a first surface grinder comprising a first rotating abrasive wheel, a first lubricant, and a first pump for circularly conveying the first lubricant to the first rotating abrasive wheel; rough surface grinding a polishing surface of the substrate in such a manner that the rotating speed of the first rotating abrasive wheel is substantially in the range from 20 r/min to 30 r/min, the grinding time period is substantially in the range from 3 minutes to 12 minutes, and the grinding pressure is substantially in the range from 1 kg/cm providing a second surface grinder comprising a second rotating abrasive wheel, a second lubricant, and a second pump for circularly conveying the second lubricant to the second rotating abrasive wheel; and finish surface grinding the polishing surface of the substrate in such a manner that the rotating speed of the second rotating abrasive wheel is substantially in the range from 30 r/min to 40 r/min, the grinding time period is substantially in the range from 5 minutes to 7 minutes, and the grinding pressure is substantially in the range from 1 kg/cm
