YM-2A Double Disc Metallographic Sample Pre Grinding Machine

YM-2A Double Disc Metallographic Sample Pre Grinding Machine

In the process of preparing metallographic specimens, pre grinding of the specimen is an essential step before polishing. Pre grinding the specimen can greatly improve the efficiency of specimen preparation. The YM-2A pre grinding machine is designed through research and collecting opinions and requirements from various users. To meet the needs of pre grinding more materials, the diameter of the grinding disc of this machine is large enough, and the speed of the grinding disc is different from most domestic products. It is a commonly used equipment for pre grinding of specimens.
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.
