YM-2A Metallographic Sample Pre Grinding MachineDetailed product description：

The YM-2A metallographic sample pre grinding machine is an essential pre grinding process in the preparation of metallographic samples, which is an essential step before polishing. Pre grinding the sample can greatly improve the efficiency of sample preparation. The YM-2A pre grinding machine is designed through research and collecting opinions and requirements from various users. In order to meet the needs of pre grinding more materials, the diameter of the grinding disc of this machine 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 of YM-2A pre grinding machine: First, clean water continuously flows into the rotating grinding disc through a water pipe. At this time, the sandpaper floating on the water surface is pushed out of the disc by the centrifugal force of the rotating grinding disc, forming a vacuum. The atmospheric pressure tightly presses the sandpaper on the grinding disc, and the pre grinding work can be carried out. When the rotation of the grinding disc stops, this function is lost, and the sandpaper can be freely removed.
