M-2 metallographic sample pre grinding machine is a wet polishing machine that uses metallographic sandpaper of different particle sizes to polish samples of various metals and alloys. By using this pre grinding machine, in addition to improving the efficiency of sample preparation by replacing manual operation with mechanical polishing, it can also completely remove plastic deformation and surface heating marks generated during the sample cutting process for further microstructure determination after polishing.

Overview of structural features:
During the operation of the pre grinding machine, cooling water is continuously injected into the rotating grinding disc through a rotary water nozzle. Under the action of atmospheric pressure, the sandpaper can tightly adhere to the grinding disc, thus avoiding the need to bond or clamp the sandpaper. This machine is equipped with a beautiful and practical fiberglass shell, completely using stainless steel standard parts, and the body will never rust, greatly enhancing the product's performance, making it an ideal equipment for sample pre grinding.
