Laser cutting is a frequently used process today for cutting a variety of materials. The high accuracy, speed and versatility of the laser are the big advantages when using a laser cutting process. Here is an explanation of how laser cutting works and for which materials it can be used.

Laser cutting procedure explained technically.

Laser cutting is a type of thermal separation process. The laser beam hits the surface of the material and heats it so strongly that it melts or completely vaporizes. Once the laser beam has completely penetrated the material at one point, the actual cutting process begins. The laser system follows the selected geometry and separates the material in the process. Depending on the application, the use of process gases can positively influence the results.

The advantages of a laser when cutting.

Here are the primary reasons to use a laser for the cutting process:


Suitable for many type of materials	No other technology can cut so many different types of organic and inorganic materials.
No post processing is necessary	Laser is a separation process in which no post processing is necessary in many cases. It even seals the edges of textiles such as synthetics or carpet, so that no unraveling starts. This saves post-processing procedures, such as mechanical sealing or sanding, depending on the type of material being processed.
High accuracy	The resulting kerf is barely larger than the laser beam itself. This makes it possible to cut very fine geometries of any shape. In addition, integrated cameras (JobControl Vision) can create registration marks and automatically compensate for the cutting path - even if the original template gets out of alignment, turned or distorted.
No tool wear	Laser cutting machines are not subject to wear, for example, tool heads do not become dull. That saves costs in ongoing operation.

Laser cutting, plasma cutting, mechanical cutting.

Cutting procedures in comparison.

Plasma cutting is a thermal fusion cutting process that is frequently used to cut steel, stainless steel and aluminum. Compared to a laser, the lower cut quality, higher energy consumption, increased dust creation and noise emissions are frequently cited as disadvantages. But when cutting any electrically conductive material, plasma cutting is often the technology of choice because of its flexibility.

Compared to mechanical chip removal cutting processes, however, a laser also often has its advantages. The non-contact processing, reduced setup costs, lower contamination and flexibility for processing are just a few of those. Depending on the material and application, every processing method naturally has its advantages, for instance, when cutting multiple samples in a stack at the same time.

What materials can be cut with the laser?

The versatility of materials that can be processed is one of the great advantages of the laser.
