POS&POH Grinding and Polishing Disc

Product Description

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.

Features

POS: Suitable for materials with hardness in the range of 40-1500HV and for softer materials or composite materials with softer substrates, need to be used with 9-3μm diamond suspension or spray.
POH: Suitable for materials with hardness higher than 150HV, and need to be used with 15-6μm diamond suspension or spray.
1.Compared with traditional silicon carbide sandpaper, POS/POH grinding discs have higher grinding efficiency and can avoid the time waste caused by frequent sandpaper replacement.
2.Lower elasticity, resulting in a higher final flatness of the sample compared to conventional silicon carbide sandpaper.
3.High quality and reliable experimental reproduction of results.
4.POS/POH grinding discs can reduce the grinding steps, save grinding time, and reduce the consumption of grinding consumables, which is in line with the concept of low carbon and green environmental protection.
