Which CNC and laser wood cutting machines suit your project?

Wood cutting offers versatile applications in laser and CNC machining. From birch plywood and MDF to dense hardwoods like oak and walnut, CO2 laser cutting machines and CNC wood cutters transform raw sheets into precise, finished pieces without compromising post-processing. Architectural models, interior signage, personalized gifts, decorative panels, flexible wooden joints: the list runs from industrial production to craft workshops.

Gravotech's laser wood-cutting machines span entry-level, small-series, and high-volume production, with CO2 laser sources optimized for clean, detailed cuts on wood surfaces. CNC wood cutters extend the range to thick timber and complex 3D profiles, with no thickness limit. Whether the brief calls for intricate design precision or heavy-duty cutting of large panels, Gravotech's technology matches your production context. Explore how.

Our laser wood cutting tips :

To achieve the best results in laser wood cutting, keep these considerations in mind:

• Edge appearance: a laser-cut edge will always have a burnt look. Use Gravostyle™ software to adjust the settings and reduce or enhance the dark appearance of the edge as needed.
• Cutting table: always use a honeycomb cutting table, pin table, or laser cutting slats to support the wood and achieve more consistent results.
• Cutting line and width: ensure a fine cutting line and utilize the cutting width correction feature in Gravostyle™ for precise dimensions.

Regular maintenance is essential to keep the equipment in optimal condition, including cleaning the optics to ensure clear performance, as laser wood cutting generates significant smoke. Using a nose cone can help protect the lens from dust and smoke, reducing the need for frequent cleaning and maintenance. Selecting the right laser lens is also crucial for achieving precise, high-quality cuts. Proper ventilation and safety measures are required to handle fumes and prevent fire hazards.

🔽What is the maximum wood thickness laser and CNC machines can cut?  

It depends on machine power, settings, and wood density. For instance, a 40W laser can cut 0.59'' plywood, but harder woods may require more passes. CNC machines theoretically have no thickness limit, as their capacity depends entirely on the specific tool length and the machine's spindle power.

🔽Which machine is the best for wood cutting applications? 

The best machine depends on your project scale. For heavy-duty cutting of large wood panels or thick timber, the best CNC wood cutters are the ISx000 series, as they offer superior power and table size. For high-precision projects requiring intricate detail, the best wood laser cutting machine is the LS900 that provides unmatched accuracy across various surface areas.

🔽Can lasers and CNC machines cut all types of wood?

Both technologies are highly versatile. Lasers cut MDF and plywood quickly, while denser solid timbers require slower speeds and power adjustments. CNC machines offer similar flexibility, with the result depending on the chosen cutting tool. In both cases, processing speed and power must be calibrated to the specific wood density.

🔽What is the "kerf" width when using a laser or CNC machine on wood? 

The kerf represents the material removed during cutting. In CNC machining, the kerf is determined by the diameter of the bit; thicker tools result in more material loss. Laser beams are significantly finer, creating a precise cut width between 0.004'' and 0.016'', which is ideal for tight-fitting joints and intricate inlays.

🔽Is a specific cutting laser table, such as a honeycomb table, essential for wood cutting?  

Using a dedicated laser honeycomb table is highly recommended. It minimizes contact with the workpiece, which helps evacuate smoke and prevents back-reflections that cause burns on the underside of the wood. This setup ensures a cleaner finish and reduces the risk of the material scorching during the cutting process.

🔽Is fume extraction required for wood cutting processes with laser? 

Yes, a high-quality fume extractor is essential for safety and air quality. Wood cutting generates smoke and potentially toxic gases. A professional three-stage filtration system covers large particles, fine dust, and gases, pre-filter, HEPA, and activated carbon in sequence. Together, they ensure a safe, smoke-free indoor working environment.

🔽How can I achieve a clean, non-carbonized cutting edge on wood with a laser? 

To prevent charred edges, use a low cutting frequency (around 1 kHz) and consistent air assist to suppress flames. Additionally, applying masking paper to the wood surface protects it from soot, resins, and smoke deposits that could otherwise darken the wood or ruin the natural grain's aesthetic.
