Best Laser Cutting Machines in India for Cutting 20mm Thick Wood
Choosing the best laser cutting machine for cutting 20mm thick wood in India depends on factors such as your budget, desired precision, and production volume. Several reputable brands, including Trumpf, Mazak, and Bystronic, are known for their high-quality laser cutting machines.
Factors to Consider When Selecting a Laser Cutting Machine
When selecting a laser cutting machine, consider the following factors:
Laser Power: The required laser power greatly depends on the thickness of the material you intend to cut. For 20mm thick wood, a laser power of at least 2 kW is recommended. Cutting Speed: Higher cutting speeds can increase productivity and reduce production time, but may also impact the quality of the cut. Aftersales Support: A reliable technology partner with robust after-sales support can help address any issues and ensure the longevity of your machine. Assist Gas: For safe and efficient cutting of wood, consider nitrogen as the assist gas. This helps in controlling fires, which could occur due to wood combustion during cutting. CO2 Laser: CO2 lasers are commonly used for wood cutting due to their efficiency and cost-effectiveness. Aftermarket Capacity: Ensure the machine has adequate space for future production growth to maximize your investment.Reputable Brands for Reliable Performance
Brands like Trotec, Epilog, and Boss Laser offer reliable performance for various wood thicknesses. It's essential to consult with industry experts and read reviews to make an informed decision based on your specific requirements.

Practical Advice on Machine Selection
To cut 20mm thick wood effectively, you will require a unit that uses compressed nitrogen as an assist gas. This helps in reducing the risk of fires during the cutting process, as wood is not flammable in a pure nitrogen environment. If the laser strikes the surface, the material will cut, and any small ember will be extinguished by the high-pressure nitrogen.
According to my experience, a 2kW CO2 laser is sufficient to cut 20mm thick wood efficiently. For reference, I have successfully cut 3/4 inch plywood (approximately 19mm thick) using a 2kW laser but couldn't cut 2 inch plywood (50mm thick). Reducing the power to 1kW might not allow you to cut through 20mm material effectively, while 1.5kW remains a viable option. However, most resonators are available in 1 or 2kW.
It's critical to request a sample of material being cut at the required power level when consulting with sellers. Most reputable sellers should be able to provide this service at a reasonable cost, if not for free, to verify the machine's performance for your specific needs.
Furthermore, understand the exact parameters you are looking for in your laser cutting machine. For example, if you plan to make furniture from 19mm plywood and intend to charge a specific price for the furniture, a 1kW laser might be enough but would take longer to cut each piece compared to a 2kW laser. Thus, ensure the laser can meet your production demands without compromising quality or efficiency.
When making a business case for purchasing a laser cutting machine, consider the total cost of ownership, including production costs, after-sales support, and potential future growth. Opting for a more powerful laser might initially seem more expensive but could be offset by increased productivity and higher sales volumes.
