Flexible vacuum brazed polishing pads are designed 6mm thick rubber layer which slow down the impact and vibration during grinding process, so the grinding effect is more even and higher grinding efficiency. With vacuum brazing technology, the diamond grains are firmly welded to the base body, and the diamond never fall off, so it is very sharp. The life is 2 times more than the electroplated type and it is suitable for the superhard materials, glass, ceramics, stone, diamonds, etc.
Hard vacuum brazed polishing pad is that the corundum is fixed on the surface of the manganese steel base by vacuum brazed technology with a hole in the center.
