In the metallographic sample preparation process, the sample pre-grinding, polishing is essential before the process, the first sample after the pre-polished, can greatly improve the work efficiency of sample preparation, YM-1A pre-mill , Through the multi-pre-grinding needs, the machine's disc diameter is greater than the domestic similar products, disc speed is also different from domestic products, is an excellent pre-grinding equipment.

YM-1A pre-grinding machine works is: first by the water through the water pipes continue to flow into the rotating disc, then floating in the sandpaper in the rotating disc under the action of centrifugal force, the sandpaper under the water thrown out of the disk, The formation of a vacuum, the pressure will be tightly pressed sandpaper under the disk, you can pre-grinding work, when the disc rotation stopped after the loss of this effect, this time the sandpaper can be free to remove.
