Laser Cutting of Sheet Metal

6/9/2026

Laser cutting is one of the most precise and versatile methods of processing metal materials. Thanks to its high accuracy, clean cut quality, and ability to handle a wide range of materials, laser technology is now widely used in both prototype and serial production.

What materials can be cut with a laser, what thicknesses are possible, and which factors have the greatest impact on cut quality?

Thanks to the seamless integration of our manufacturing technologies, we produce sheet metal components with outstanding quality, repeatability down to tenths of a millimeter, and minimal production downtime.

What Is Laser Cutting and How Does It Work?

Laser cutting is a process in which material is cut using a highly concentrated laser beam. The beam locally heats, melts, or vaporizes the material, enabling precise cutting according to a programmed path.

Key advantages of laser cutting:

high precision and repeatability,
clean cut edges,
minimal heat-affected zone,
ability to cut complex geometries without additional machining.

What Materials Can Be Laser Cut?

Laser cutting is suitable for a wide range of metal materials.

The most common include:

carbon steel,
stainless steel,
aluminium.

Thanks to modern fiber laser technology, materials that were previously more challenging to process can now be cut efficiently and with excellent quality.

What Material Thicknesses Can Be Cut?

The maximum cutting thickness depends primarily on the laser power, material type, and required cut quality.

In general:

thinner sheets allow very fast cutting with exceptional precision,
thicker materials require optimized power settings and cutting parameters,
for visible components, thinner materials are often preferred to achieve the highest edge quality.

Modern Salvagnini laser systems can efficiently process sheet metal across a wide range of thicknesses while maintaining consistent cut quality.

What Influences Laser Cutting Quality?

Laser Type and Power

Laser power directly affects cutting speed, maximum material thickness, and cut quality.

Higher power enables:

processing thicker materials,
faster production speeds,
greater process stability for complex geometries.

Material Properties

Every material reacts differently to the laser beam. For example, aluminium has different thermal conductivity characteristics than steel, which influences both cutting parameters and edge appearance.

Machine Accuracy and Process Control

Modern laser systems use adaptive control technologies that automatically optimize cutting parameters according to the material type and part geometry.

This is essential for:

consistent cut quality,
minimizing burr formation,
maintaining production repeatability.

Salvagnini Laser Systems in Practice

Salvagnini laser systems are designed for maximum productivity and flexibility. Their combination of power, precision, and automation makes them suitable for both custom projects and large production runs.

In practice, this means:

rapid response to changing production requirements,
manufacturing precise laser-cut parts ready for further processing,
efficient integration with downstream operations such as bending and powder coating.

Laser Cutting as the Foundation for Further Processing

The quality of a laser-cut part has a significant impact on subsequent manufacturing operations.

Accurately cut components simplify:

sheet metal bending without additional adjustments,
assembly of individual components,
achieving high-quality surface finishes.

Laser cutting is therefore often the first and one of the most important steps in the entire manufacturing process.

When Is Laser Cutting the Ideal Solution?

Laser cutting is the ideal choice when the priority is:

precision and edge quality,
production flexibility,
fast delivery times,
compatibility with subsequent manufacturing processes.

A properly selected laser cutting system therefore forms the foundation of efficient modern metal manufacturing.
