Many times when operating a laser cutting machine, there will be problems such as opaque cutting, burrs, and uneven cutting surfaces. The cutting ability of a metal laser cutting machine is related to the quality (power), environment, laser type, cutting speed and other factors of the cutting machine. Auxiliary gas can improve a certain cutting ability, so there is no absolute standard to judge its cutting thickness.

Cut QualityNarrow Kerf Width: Generally 0.1 – 0.5 mm
High Precision: Typical hole center distance error of 0.1 – 0.4 mm, contour size error of 0.1 – 0.5 mm
Smooth Cut Surface: Roughness usually Ra 12.5 – 25 μm
Minimal Post-Processing: Welding is often possible without further processing
Cutting SpeedExample with 2KW Laser Power:
Carbon steel (8mm thick): Cutting speed of 1.6 m/min
Stainless steel (2mm thick): Cutting speed of 3.5 m/min
Minimal Heat Affected Zone and Deformation: The area affected by heat is small, resulting in very little deformation

Laser cutter wattage chart

  • Acrylic: Higher power for thicker sheets. Speeds must be adjusted for smooth cuts and to prevent melting.
  • Leather: Power and speed vary with thickness and type. Lower power and higher speed for thin leather to avoid burning.
  • Cardboard: Moderate power; higher speeds to prevent burning and ensure clean cuts.
  • Knife Template Paper: Typically requires moderate power. Adjust speed for clean cuts without burning.
  • MDF: Requires higher power for thicker boards. Speeds should be managed to avoid charring.
  • Rubber: Settings depend on rubber type and thickness. Adjust to prevent melting or deformation.
  • Glass: Low power and very slow speeds due to sensitivity to thermal stress.

How thick can a laser cutter cut

Laser cutting thickness can be determined according to different materials and the power of the laser cutting machine.
Generally speaking, the cutting thickness of metal materials is relatively large, which can reach 100 mm or even thicker. For example, a 40000W ultra-high power laser cutting machine can easily cut metal plates thicker than 100 mm;

Laser Cutter PowerMax Thickness of Carbon Steel (mm)Max Thickness of Stainless Steel (mm)Max Thickness of Aluminum Plate (mm)Max Thickness of Copper Plate (mm)Notes
4500WN/A20N/AN/AQuality not assured above 12mm
6000WN/AHigherN/AN/ABetter cutting ability, higher price

For metal materials, use high-power fiber lasers or carbon dioxide lasers for cutting. These lasers can Generally speaking, the cutting thickness of metal materials is directly proportional to the laser power. For more common metal materials such as stainless steel, aluminum alloy, etc., the laser cutter thickness can range from a few millimeters to hundreds of millimeters.

What determines the cutting thickness of a laser cutting machine?

  • Laser power
  • Lens depth
  • cutting material

4 Factors affect laser cutting speed table:

Cutting materials:

Different materials have different melting points and thermal conductivities, which indirectly leads to different cutting effects.

Material thickness:

Choosing the appropriate cutting thickness range will help increase the cutting speed.

Laser power:

Different powers have certain limits on cutting speed. Choosing the appropriate power according to the material being cut will help maximize the effect.

Cutting speed:

The fiber laser cutting parameters have a great impact on the cutting speed.
