Laser Cutting of Stainless Steel

High Burr Latitude and Minimal Thermal Impact

Stainless steel is processed with laser fusion cutting. CO2 and also solid-state lasers are suited for this kind of applications, with CO2 lasers being preferred for cutting of thicker materials.  CO2 lasers cut stainless steel and construction steel at a cutting speed of 18m/min at a material strength of 1 mm.

In micro material processing solid-state lasers (fiber laser, pulsed Nd:YAG) are commonly applied for laser cutting stainless steel, providing cut widths down to 20 microns depending on the steel thickness.

These laser cuts typically come with dross-free quality and minimal heat affected zones.

  • High speeds of operation, excellent quality of cut edges and low heat affected zones render 2D laser cutting of stainless steel interesting for a broad range of applications. Cutting of hifi-housings, knives, scalpels or bone saws may be mentioned as an example. For scalpels a specific stainless steel is used, which is difficult to die cut. Here, laser cutting is an attractive alternative. Due to fast retooling times many different forms can be realized within a short period of time.

  • Finest tubes like implants or stents can be cut at cutting speeds of up to 20 mm/s on the fly at max. 20 revs/sec. Cut widths smaller than 20 microns showing excellent cutting edge qualities can be achieved both with dry and wet cutting – and non-radial cuts can be generated as well.For these applications we recommend

  • Three-dimensional components of stainless steel, such as pipes, which are amongst other things applied in architecture, can be furnished cost-effectively with suitable sections with the help of system technology.With lasers manifold outlines in almost any resolution can be cut. Thus, for instance, many thousand fine trenches can be inserted for a liquid filter into a Stainless steel plate. Thereby up to 500 trenches per cm2 are feasible.

Why Do We Use Laser Cutting?

As mention previously, it is an alternative to the etching process, but there are also many other benefits. Not only can laser cutting deliver high levels of precision, very accurately, but it is consistent in doing so, with very little room for human error. This means there is less energy used, less wastage, and is, therefore, a lower cost solution.

More complex designs can be implemented, on smaller parts than with etching and still leaves metals burr-free and clean cut. In addition to this, laser cutting means there is less workpiece contamination, which aids machine longevity.

How Do We Use it?

So, just  what is laser cutting used for? As laser cutting can be used on sheet metals; such as aluminium, stainless steel, mild steel and titanium among many others, it can be used for components and parts used with any of the  industries we serve. Furthermore, laser cutting is versatile in that it can be used on other materials as required by our customers.

All of our components can be processed to  yield maximum results. We can use sheets up to 3000 x 1500mm, with a thickness of up to 20mm; depending on the metal used.
