Polishing Cloth for Metallographic Sample Preparation

Description

Product Introduction:

　Our company has developed and manufactured a series of metallographic polishing fabrics, specifically designed for both coarse and fine polishing during metallographic sample preparation. These fabrics are compatible with various domestic and international models and specifications of metallographic polishing machines, particularly well-suited for manual, semi‑automatic, and fully automatic metallographic grinding and polishing equipment. When used in conjunction with our diamond‑based grinding and polishing product line and our metallographic polishing lubricant‑coolant, this series of polishing fabrics delivers a mirror‑like finish.
