Basics of laser cutting

Definition and function of laser cutting

Laser cutting is a manufacturing process in which a high-intensity laser beam is used as a tool for cutting materials. The laser beam is guided through a system of mirrors or glass fibres and focused on a very small spot. This focussing makes it possible to concentrate an enormous amount of energy on a small area, causing the material to melt, burn or be separated by vaporisation at the desired point. The movement of the laser beam is controlled by a computerised system, which enables high precision and repeatability.

Differences between laser cutting and other cutting techniques

Compared to traditional cutting techniques such as mechanical cutting or plasma cutting, the Laser cutting offers several advantages. Mechanical cutting methods can stress the material through direct contact and are often less precise. Plasma cutting, although suitable for thicker materials, cannot achieve the same cut quality as laser cutting, especially for fine details. Laser cutting, on the other hand, enables a non-contact cut, which means that no mechanical stress is applied to the material. This results in more precise cuts and a better surface quality.

Advantages of laser cutting for metal processing

Laser cutting offers numerous advantages in metal processing:

Precision: Laser cutting enables extremely precise cuts with tight tolerances. It can realise complex contours and fine details that are not possible with other methods.
Versatility: Various metals and alloys, including stainless steelcan be cut efficiently. It is also possible to process different material thicknesses.
Speed: Compared to traditional methods, laser cutting is often faster, especially for complex cuts or fine details.
Low heat influence: As the laser beam is very precise, the surrounding material is heated less. This reduces the risk of material deformation.
Contactless processing: As the laser beam does not physically touch the material, there is no tool wear and no mechanical stress on the workpiece.
Automation and integration: Laser cutting systems can be easily integrated into existing manufacturing processes and can be fully automated, increasing the efficiency and consistency of production.

These advantages have made the Laser cutting has established itself as a favoured method in modern metalworking, especially when it comes to processing high-quality materials such as stainless steel.

Laser cutting of stainless steel

Special features of stainless steel compared to other metals

Stainless steel differs from other metals in several important ways, making it a unique and sometimes challenging material for laser cutting. Its salient properties include high corrosion resistance, considerable strength and excellent durability. These properties are due to the composition of stainless steel, which contains various alloying elements such as chromium, nickel and molybdenum. These additives not only give stainless steel its characteristic properties, but also influence its behaviour during laser cutting.

Challenges in laser cutting stainless steel sheet

Laser cutting stainless steel presents specific challenges:

Heat conduction: Stainless steel conducts heat efficiently, which means that the heat from the laser beam can spread quickly through the material. This can lead to a change in the material properties in the vicinity of the cut area.
Reflection: High-gloss stainless steel surfaces can reflect the laser beam, which impairs the efficiency of the cutting process and harbours potential safety risks.
Oxidation: Oxidation can form on the cut edges during cutting, which can impair the quality of the cut.

Technical requirements and settings for optimum results

Specific technical requirements and settings are needed to overcome these challenges and achieve optimum results when laser cutting stainless steel:

Laser power: A sufficiently high laser power is required to cut efficiently through the stainless steel. The exact power depends on the thickness and type of stainless steel.
Gas flow: The use of cutting gases such as nitrogen or argon can help to prevent oxidation and achieve a clean cutting edge.
Pulse rate: Adjusting the pulse rate of the Lasers can help to minimise the heat-affected zone and enable more precise control of the cutting process.
Focussing of the laser beam: Precise focusing of the laser beam is crucial in order to minimise reflection and maximise energy efficiency.
Cutting speed: The cutting speed must be carefully adjusted to achieve an optimum balance between cutting quality and efficiency.

By taking these technical aspects into account, laser cutting of stainless steel can be carried out efficiently and with high quality, making it a favoured method in many industrial applications.
