Application<\/h2>\n

REMDRUK supplies new chrome metering rollers for the Heidelberg Speedmaster CD 74 sheet-fed offset press and refurbishes used rollers. In the Alcolor dampening unit, the metering roller takes fountain solution from the rubber water pan roller and passes it to the form roller; the pressure between the two sets the water film thickness. Chrome wets well with water, while the hard surface maintains its dimensions and smoothness over time.<\/p>\n

A consistent diameter and uniform surface along the full roller length are essential for an even water film across the print width.<\/p>\n

Chrome and surface finish<\/h2>\n
\n
\n

0.15 mm hard chrome<\/h3>\n

Standard and recommended coating thickness. Thicknesses of 0.1 or 0.2 mm are available on request. Chrome hardness: 63 HRC.<\/p>\n<\/div>\n

\n

Grinding and polishing<\/h3>\n

After chrome plating, the roller is ground to size and polished to Ra 0.08 \u00b5m. Where a smoother surface is required, Ra 0.04 \u00b5m is available.<\/p>\n<\/div>\n

\n

Made to size<\/h3>\n

A new roller is manufactured from a drawing, sample roller or measurements taken at your facility.<\/p>\n<\/div>\n<\/div>\n

Refurbishment<\/h2>\n

During refurbishment, all old chrome is removed from the worn roller, a new layer is applied, and the roller is ground and polished to size. State in your enquiry if the roller must be restored to its nominal diameter. Refurbishment usually takes 5\u20138 weeks.<\/p>\n

The steel condition can only be assessed after the chrome has been removed, when corrosion or microcracks may become visible. If this happens, we inform you and agree any further work before proceeding.<\/p>\n
