Product Overview
The Stainless Steel Coil No.4 Polishing Machine is a fully automatic production line developed for continuous grinding and polishing of stainless steel coils. Using multiple abrasive belt stations combined with precision tension control and intelligent automation, the machine produces a uniform, attractive No.4 satin finish across the entire coil surface.
Unlike conventional polishing machines, OUYIGANG’s production line is engineered specifically for long-term industrial operation. Every component—from the polishing heads and drive system to the electrical control cabinet—is designed to maximize stability, minimize maintenance, and ensure consistent surface quality.
With more than 25 years of experience in stainless steel surface finishing equipment, OUYIGANG supplies customized polishing lines that meet different production capacities, material specifications, and factory layouts.
