產品介紹
在金相試樣制備過程中，試樣的預磨，是拋光前常用的前道工程，先將試樣預磨光后，可大大提高試樣制備的功效，YM-2A預磨機，是通過對多方面的調研和采集多方面使用人員的意見及要求設計而成，為適應更多材料預磨的需要，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，是試樣預磨的較好設備。
YM-2A預磨機的工作原理：先由清水通過水管不斷流入旋轉的磨盤中，這時浮在水面的砂紙在旋轉磨盤離心力的作用下，將砂紙下的水拋出盤外，形成真空，大氣壓便將砂紙緊緊地壓在磨盤上，即可進行預磨工作，當磨盤旋轉停止后即失去這種作用，此時砂紙便可自由取下。
During Metallurgical Sample preparation, pre-grinding is a necessary prevenient work of polishing. Pre-grinding the samples can greatly improve preparation efficiency. YM-2A was designed after collecting many customers’ suggestions and requests. To adjust to all kinds of material pre-grinding, the grinding wheel size of YM-2A is larger than the same products in china. The rotating speed is different from other products. YM-2A is the best choice for metallurgical sample pre-grinding.
Working Principle of YM-2A：Through pipe, water flow to the rotating grinding wheel. The eccentrical force throws the water under grinding disc, and forms vacuum which attracts it to do pre-grinding work. Stop rotating, the eccentrical force loses and the grinding disc can be taken off.
