NU: Strip surface treatment by metal-cutting

The JULIUS product range offers the modular series NU and TRINU as well as the groove dressing machine for the machining of the strip surface.

The machines of each series can be combined with elements of modular strip edge trimming.

Due to a compact construction method, the machines of the modular series can easily be integrated into existing lines or even retrofitted later as an extension.

With one tool the grooving machine of the series NU removes a layer of coating from the strip surface. The tool can be adjusted vertically and horizontally.

The grooving machine of the series DNU is composed of two grooving modules installed serially.

The DNU U machines two layers of coating from the bottom side of the strip. This unit is used when the groove has to be on the bottom side of the strip.
