High precision and cutting fine contours and detailed items. First, it saves material to some extent. The exposure area of the laser beam is 0.3-0.5 mm therefore the beam does not “eat up” extra material as, for example, a milling machine does (you can read about it in the article about CNC routers). Secondly, you can obtain the result that is unattainable or difficult to achieve with other types of machining;

Speed of operation. The Wattsan wood laser cutting machines achieves operating speeds of up to 500 mm/s and idle or engraving speeds of up to 700 mm/s;

No time wasted on attaching the workpiece because the cutting is non-contact;

For the same reason, there is no chipping or notches at the edges of the product which can occur with traditional wood-cutting methods;

In addition to laser cutting, you can also perform engraving and ablation of wood on a wood laser machine. This significantly expands the possibilities for your production and allows you to get creative with the process;

The CNC brings down to a minimum the possibility of errors during operation because all manipulations are performed by the programmed controller;

For the same reason, the laser ensures high quality, precision, and repeatability of products;

Processing of a number of other materials: different types of plastics, rubber, ceramic, fabric, fur, and leather, foam, cardboard and paper, stone, composites. When combining materials and methods of processing, your possibilities are only limited by your imagination.

CO2 Laser Cutting Thickness (only for reference)

What Thickness Can a Wood Laser Cutter Handle?

A properly adjusted laser cutting machine with a 100 W laser tube cuts 10 mm thick wood although it can handle thicknesses up to 20 mm. However, please note that in this case, the operating speed will be 2 mm/s, and there will be soot at the edges.

Solid wood thicker than 5 mm is rarely cut out with a laser – there is noticeable soot on the material that requires additional post-treatment. If your main task is to cut out thick wooden materials without fouling, we recommend to use CNC router machines.

Tips for Cutting Cutting Machine Wood

To achieve optimal results when working with wood laser cutting machines, follow these best practices for material selection, equipment use, and post-treatment:

Material Quality

Start by selecting high-quality wood with a uniform color and structure, avoiding knots and imperfections. This ensures consistent cutting quality and helps achieve smooth, predictable results. The more homogenous the wood, the better the final outcome will be, minimizing inconsistencies in machining.

Edge Cleanliness with Air Compressor

To prevent fouling and achieve clean, light-colored edges, it’s essential to use an air compressor during cutting. Supplying 1-2 atm of air pressure to the cutting area, as recommended by Wattsan engineers, helps blow away debris and soot, leading to cleaner cuts and a polished finish.

Laser Power Usage

For optimal performance and extended machine life, it's advised to run the laser emitter at no more than 75% of its maximum power. While running at full power might not dramatically impact the cutting results, operating at a lower power level helps prolong the life of the laser tube without compromising quality.
