Laser Cutting of Mild Steel

Complex, Multi-Dimensional Cutting Made Easy

Laser Cutting of Mild Steel

The cutting in two dimensions is a domain of the CO2 laser. Typical cutting speeds for mild steel are for example at 18m/min for 1 mm, 4.5 m/min for 3 mm and 1.5 m/min for 8 mm material strength. Basically, the cutting of metals with lasers happens through the local heating of the material above its melting point in the focal point of the focused laser. The resulting molten material is ejected by a gas flow oriented coaxially to the laser beam so that a kerf is formed.

For low-alloyed steels in particular, oxygen is typically used as cutting gas. At the moment the maximal processable counter thickness for laser flame cutting of steel is approximately at 25 mm.

  • Mild steel is the most frequently cut material in the industry. Thus e.g. gears, blinds, coverings or chain links of mild steel are cut using lasers.

  • In combination with fiber optic (solid-state laser) or mirror systems (CO2 lasers) also complex, three-dimensional mild steel components can be cut such as hydroformed parts for the automotive industry.

Laser Cutting in Semiconductor Industry

In semiconductor industry lasers are used for leadframe cutting or hybrid cutting processes. The scanner-based cutting technology is fast and flexible enough to interact closely with preceding functional tests. With extremely small kerf widths even the tiniest lead structures can be processed.

Separation of certain highly integrated packagings, like QFN packages, requires cutting of composite material – e.g. leadframe and mold compound. A combination of soft and hard material which makes mechanical sawing slow and prone to wear. In contrast, hybrid cutting with our lasers open up new vistas for clean and fast cutting of this type of composite materials.
