POH and POS abrasive discs provide an efficient alternative to metallographic sandpaper for fine grinding. After the sample surface is ground with a diamond grinding disc or coarse sandpaper, use POS/POH fine grinding disc with diamond polishing liquid (3μm-15μm) for fine grinding. After two steps of polishing, a perfect sample surface can be obtained.

POS/POH grinding discs replace multiple grinding steps with one step, typically P320–P2000. It can reduce grinding steps while ensuring high-quality results. Its consistently high removal rates and long service life compared to traditional sandpaper means no more time wasted changing abrasive media, significantly reducing overall sample preparation time. POS/POH grinding discs are ideal for making large batches of samples with high reproducibility.
