YMP-2-300/250 Metallographic Sample Grinding and Polishing Machine

In the metallographic sample preparation, pre-grinding, polishing and grinding are the indispensable procedures. This machine is controlled by single chip microcomputer. With ABS sewage collection plate and cover it is the latest product with a new and beautiful appearance. With grinding disc stepless speed regulation and clockwise or anticlockwise direction, it ensures the smooth of the sample. It adopts high definition LCD touch screen, clear to display and easy to use. The motor is DC brushless motor and don’t need to replace the brush, used for a long time. The grinding disc is stainless steel which makes firm and steady. Strong large support chassis design ensures the precision rotary balance. Powerful motor brings strong power and efficient grinding and polishing experience. Spindle leak-proof design ensures the bearing almost without damage and the super mute design brings a good experience. With magnetic grinding disc design, it supports for fast disc replacing system, the plate is Teflon painted which makes no residue of changing polishing cloth. The size of the disc is larger than the same products in the market, adapted to various materials preparation of test samples. The two discs operate independently. With low noise, convenient operation, beautiful appearance, safe use, it is the ideal equipment for metallographic sample preparation.
