YM-2A Metallographic Sample Pre-grinder

During metallographic 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 metallographic sample pre-grinding.

Working Principle of YM-2A: Through pipe, water flow to the rotating grinding wheel. The ex-centric force throws the water under grinding disc, and forms vacuum which attracts it to do pre-grinding work. Stop rotating, the ex-centric force loses and the grinding disc can be taken off.
