Grinding & Polishing System for Metallographic Sample Preparation
In the process of metallographic sample preparation, the grinding and polishing of the sample is an indispensable process. After the sample is ground and polished, a bright mirror-like surface can be obtained. The eGP-2T metallographic sample grinding and polishing machine adopts high quality touch screen control, adjustable stepless speed between 50-1000r/min. The grinding and polishing of the sample can be completed by replacing the metallographic sandpaper and polishing fabric. It is especially suitable for metallographic laboratories in factories, colleges and research institutes.
