Titanium Surface Finishing MachinesContinuous titanium coil-to-coil polishing line for TA1, TC4 and nickel strip 300–750 mm wide and 0.05–2.0 mm thick, with wet abrasive-belt No.4 finishing and CPC/EPC control.
Our lines process coils and sheets of stainless steel, titanium, aluminum, nickel alloys and other metals, in thicknesses from 0.05 to 10.0 mm and widths from 300 to 2000 mm.
Depending on the required finish — No.4, Scotch-Brite, Hairline, BA, 6K, 8K or Super 8K — we configure the grinding, sanding and brightening sequence to reach the specified roughness (Ra), in both coil-to-coil and sheet-to-sheet processes.
No.1
Ra > 3 µm
2D
Ra 1–2.5 µm
2B
Ra 0.1–0.5 µm
BA
Ra < 0.3 µm
No.4
Ra 0.2–1.5 µm
8K
Ra < 0.1 µm
No.4 and Hairline finishes are the most requested on stainless steel surfaces for the elevator industry, home appliances and architectural hardware, while 8K mirror polishing is reserved for high-end decorative applications. Our No.4 polishing machines also process aluminum sheets.
In steel mills, our lines are integrated as a stage of the rolling train: they remove oxide scale and condition the surface to make the next rolling pass easier.
