The laser beam is generated by a laser resonator and directed through a series of mirrors or fiber optics to the cutting head, where it is focused on the workpiece. Laser-cutting machines are capable of cutting a wide range of materials, including metals, plastics, wood, and more, with high accuracy and speed.
- Cutting Method
- CNC Cutting: CNC cutting machines use mechanical tools, such as blades, drills, or cutting heads, to physically remove material from the workpiece. The cutting tool is controlled by a computer program that specifies the cutting path and parameters.
- Laser Cutting: Laser cutting machines use a focused laser beam to melt, burn, or vaporize material along the cutting path. The intense heat generated by the laser beam results in a clean and precise cut, with minimal material deformation or tool wear.
- Precision and Accuracy
- CNC Cutting: CNC cutting machines can achieve high levels of precision and accuracy, depending on the type of cutting tool and the machine’s capabilities. However, the cutting accuracy may be limited by factors such as tool deflection, wear, and material properties.
- Laser Cutting: Laser cutting offers exceptional precision and accuracy, with the ability to cut intricate shapes, fine details, and tight tolerances. The laser beam can be focused to a very small spot size, allowing for precise control over the cutting process.

However, the suitability of laser cutting for specific materials depends on factors such as material thickness, composition, and optical properties.
What Materials Cannot Be Cut By A Laser Cutting Machine?
While laser cutting is a versatile and widely used method for cutting various materials, some materials cannot be effectively cut or are not suitable for laser cutting due to their properties. Here are some examples:
- Reflective Materials: Highly reflective materials such as copper, brass, and aluminum can reflect the laser beam instead of absorbing it, making it challenging to cut them effectively. The reflective nature of these materials can cause damage to the laser optics and reduce cutting efficiency. While it’s possible to cut thin sheets of reflective metals with specialized lasers, thicker or highly reflective materials may require alternative cutting methods.
- Transparent Materials: Transparent materials such as glass and certain plastics are not suitable for laser cutting because the laser beam passes through them without significant absorption or cutting action. Instead of cutting, the laser beam may cause melting or charring on the material’s surface. However, lasers can be used for engraving or marking transparent materials by creating surface patterns or markings.
- PVC and Vinyl: Polyvinyl chloride (PVC) and vinyl materials are not recommended for laser cutting due to the release of toxic gases and corrosive byproducts when exposed to the high temperatures generated by the laser beam. Cutting PVC or vinyl with a laser can produce harmful fumes and damage the laser-cutting machine’s optics and components. It’s safer to use alternative cutting methods for these materials.
- Certain Ceramics and Stones: Some ceramics and natural stones, such as granite and marble, are challenging to cut with lasers due to their hardness and composition. While lasers can engrave or etch these materials, cutting them with lasers may require specialized equipment and techniques. Waterjet cutting is often preferred for cutting hard and brittle materials like ceramics and stones.
- Certain Composites and Laminates: Some composite materials and laminates contain layers of different materials bonded together, making them difficult to cut with lasers. The varying material properties and adhesives used in composites and laminates can result in inconsistent cutting quality and may damage the laser cutting machine’s optics. Alternative cutting methods such as CNC milling or waterjet cutting may be more suitable for these materials.
