We have a strong and professional technical team who successfully developed diamond sanding belts, diamond flap discs, diamond spiral bands and diamond hand pads what are of the independent intellectual property rights. And we also firstly researched some high level super coated abrasives, such as CBN belts, CBN flap discs, CBN spiral bands and CBN hand pads. Superhard material coated abrasives have the dual advantages of flexibility of traditional coated abrasives and high hardness of superhard materials. Diamond belts are widely used in grinding & polishing process for complex shapes and surfaces of hard brittle materials, such as stone, glass, ceramic, monocrystalline silicon, synthetic materials, hard.
