YM-1A type metallographic specimen pre grinding machineDetailed product description：

Purpose:
The YM-1A metallographic sample pre grinding machine is an essential pre grinding process before polishing in the preparation of metallographic samples. Pre grinding the sample can greatly improve the efficiency of sample preparation. The YM-1A pre grinding machine is designed to meet the needs of multiple pre grinding processes. The diameter of the grinding disc is larger than that of similar domestic products, and the speed of the grinding disc is also different from that of domestic products, making it an excellent equipment for sample pre grinding.

The working principle is:
First, clear water continuously flows into the rotating grinding disc through the water pipe. At this time, the sleeping sandpaper is thrown out of the disc by the centrifugal force of the rotating grinding disc, forming a vacuum. The atmospheric pressure tightly presses the sandpaper under the disc surface, and pre grinding work can be carried out. When the rotation of the grinding disc stops, this effect is lost, and the sandpaper can be freely removed.
