Green silicon carbide 500# for polishing glass ball

Green silicon carbide 500# is an ideal polishing powder for precise glass balls. The precise glass ball often gets tiny tolerance. And the surface is smooth without scratches. Fine polishing powder has to choose to complete the work.

Precise glass balls are always of Borosilicate glass and optical glass. Those are very hard glass compare with normal Soda-lime glass so they can bear the higher strength and get steady performance. Therefore, it has to use extremely hard polishing media. The green silicon carbide is just the one that gets high hardness and lowers cost than diamond.

Green silicon carbide 500# is a very fine powder with D50 23-27um. The powder could make glass balls get a tolerance within 0.02mm.
