Surface finishing

In-house technology for roll polishing and textured surfaces

TIR and parallelism close to perfection

Roll polishing

Ultra-finish chrome rolls are typically used in the manufacture of plastic film, photographic film, plastic, sheet and glass. As all the pre-grinding, inspection, chrome plating, degassing, finish grinding and polishing is done in-house, we have total control over the finished product and so guarantee repeatable quality and realistic lead times.

Our in-house techniques, developed over many years, enable us to produce high quality mirror polished chrome plated rolls with surface finishes as fine as Ra 0.005um – with TIR and parallelism close to perfection.

Textured surfaces

BEP can produce a wide range of matt, silk and textured surfaces by grit/sand blasting and various electrolytic techniques. The different surfaces can be achieved by varying the blast media, media size, nozzle size, pressure and duration.

Using these methods, we can create a wide range of textures from fine RA 0.1um to rough Ra 15um.  Generally these finishes are used for producing plastic sheet, photographic paper, laminating and coated steel strip.
