The thickness that a laser cutter can cut through depends on several factors, including the type of laser, the material being cut, and the specific configuration of the laser cutting system. Here’s a general overview:
Type of Laser: There are different types of laser cutters, such as CO2 lasers, fiber lasers, and Nd:YAG lasers. Each type has different capabilities and power levels, which influence the maximum cutting thickness.
Material: The type of material being cut greatly affects the maximum thickness. Metals like steel can be cut thicker than materials like acrylic or wood. For instance, a high-power laser cutter can cut through steel up to around 20-25mm thick, but the same machine might cut through much thicker acrylic or wood.
Laser Power: The power of the laser is a critical factor. Higher power lasers (measured in watts) can cut through thicker materials. For example, a 1kW laser might cut steel up to about 10mm thick, while a 4kW laser could cut up to around 20mm or more.
Cutting Speed and Quality: There’s often a trade-off between the thickness of the material and the quality and speed of the cut. Cutting thicker materials usually requires a slower speed to maintain a clean, precise cut.
Laser Configuration and Focus: The setup of the laser, including the focal length of the lens and the type of gas assist used (like oxygen or nitrogen), also influences the maximum cutting thickness.
