Bridge-Type Single Head Manual Polishing Machine | Joborn SF-2500 / SF-3000
Product Overview
The SF-2500 / SF-3000 bridge-type single head manual polishing machine is designed for flexible stone surface grinding and polishing, especially suitable for factories that require manual control, high adaptability, and cost-effective processing.
Unlike automatic polishing lines, this machine adopts a bridge structure with a single polishing head, allowing operators to manually control the polishing path, pressure, and speed.
It is widely used for stone slabs, profiles, edges, columns, and special-shaped stone surfaces.
JOBORN SF2500/3000 Manual Polishing Machine. This machine uses round column as its guide slip surface for steady automatic lifting up and down. The machine is applicable to plane grinding and polishing of slabs with greatly various thickness, tombstones, and stone with design. The worktable can be selected for grinding crafts camber inside and outside.
