Revolution in solid-state laser cutting

A swift change from maximum productivity and quality in cutting thin sheets to the quality cutting of thick sheets – the TruLaser 5030 fibre achieves this flexibility with the new BrightLine fbre function. TRUMPF’s new 2D laser machine cuts even stainless steel up to 25 millimetres thick in outstanding quality with its 5-kilowatt laser. In addition, BrightLine fbre allows particularly small holes and contours to be cut in thick stainless steel as well as increasing quality and productivity in the processing of mild steel between 15 and 25 millimetres in thickness. It can also cut through aluminium sheets up to 25 millimetres thick. In short, it can process all common material types and thicknesses in very good quality and is a genuine all-purpose solid-state laser machine.

Now with BrightLine fbre

A perfect interplay of beam generation, guidance, and focusing are crucial for the BrightLine fibre function. TRUMPF is a one-stop shop for all these key elements, from lasers and beam guidance to the cutting head. The company also builds on process know-how it has acquired over decades, enabling it to match the different elements to each other so that they work together optimally – a prerequisite for technological progress in solid-state laser cutting.

One important advantage is the higher quality achieved in thicker mild and stainless steel. Although the TruLaser 5030 fbre with solid-state laser was previously capable of cutting stainless steel up to 20 millimetres thick and mild steel up to 25 millimetres thick, burring and uneven cutting surfaces ensued when it tackled higher material strengths. When cutting thick mild steel, moreover, fluctuations in material quality could lead to poorly executed cuts or cutting tears. Now BrightLine fibre considerably reduces burring and the roughness values of the cut edge and increases process reliability when cutting mild steel. In addition to the signifcant improvement in cutting quality, the maximum sheet thickness that the machine can cut with a 5-kilowatt laser in aluminium and stainless steel has increased from 20 to 25 millimetres.

Used in conjunction with BrightLine fibre, a new multi-stage piercing process offers additional advantages when cutting stainless steel. It prevents slag from forming when the laser beam pierces the sheet. This means that the machine no longer has to give the piercing site a wide berth and can execute even fner contours than have been possible to date. To take one example, this enables the TruLaser 5030 fbre to attain minimum contour diameters of one millimetre when cutting stainless steel twelve millimetres in thickness. BrightLine fbre also facilitates the removal of parts, as they are easier to extract from the scrap skeleton. This saves time during manual unloading and increases process reliability during automated unloading.

With the TruLaser 5030 fibre and BrightLine fibre, the solid-state laser has made the successful leap into all-purpose 2D laser processing. This highly productive machine cuts mild steel, stainless steel, and aluminium up to 25 millimetres thick in outstanding quality. The TruLaser 5030 fbre is also suitable for cutting non-ferrous metals such as copper and brass up to sheet thicknesses of ten millimetres.
