PA-2-type in the metallographic sample preparation process, the pre-polishing is essential before the polishing process, the first sample after the pre-polished, can improve the effectiveness of sample preparation,

A variety of pre-grinding material needs, the machine's disc diameter is greater than similar products, disc speed is also different from similar products, is an excellent pre-grinding equipment.

LPA-2 pre-grinding machine works: first by the water through the water pipe continuously into the rotating disc, then floating in the water of the sandpaper in the rotating disc centrifugal force, the sand

Paper under the water thrown out of the disk, the formation of a vacuum, the pressure will be tightly pressed on the sandpaper sandpaper, you can pre-grinding work, when the disc rotation stopped after the loss of this

Use, then sandpaper can be free to remove.
