The application of grinding products in the sanitary ware industry is crucial. Bathroom products (such as faucets, showerheads, shower tubes, pendants, bathroom cabinet mirrors, etc.) have the characteristics of complex shapes (multi curved surfaces, deep cavities), diverse materials (copper, zinc alloy, stainless steel, glass, ceramics), and extremely high surface requirements (corrosion resistance, high gloss, smooth hand feel). The grinding process directly determines the fingerprint resistance, corrosion resistance, and appearance texture of the product.
