Pre grinding machine for metallographic specimens

Pre grinding machine for metallographic specimensIn the process of preparing metallographic specimens, the pre grinding of the specimen is the first step before polishing. Pre grinding the specimen can greatly improve the efficiency of specimen preparation. The YM-1A pre grinding machine is designed to meet the needs of multi-party pre grinding. 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 a device for pre grinding specimens.
YM-1APre grinding machine for metallographic specimensThe working principle of the sandpaper is as follows: first, clean water continuously flows into the rotating grinding disc through a water pipe. At this time, the sandpaper floating in sleep 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 function is lost, and the sandpaper can be freely removed.
