在金相試樣制備過程中，預磨是拋光前的前道工程，先將試樣預磨光后，可提高試樣制備的功效，為適應在多種材料預磨的需要，該機的磨盤直徑大于國內同類產品，磨盤的轉速也不同于國內同類產品，是試樣預磨的優質設備。
During Metallurgical Sample preparation, pre-grinding is a necessary prevenient work of polishing. Pre-grinding the samples can improve preparation efficiency. To adjust to all kinds of material pre-grinding, the grinding wheel size of YM-2 is larger than the same products in china. The rotating speed is different from other products. YM-2 is the best choice for Metallurgical Sample pre-grinding.
