Co2 laser cutting machine is the equipment uses co2 glass laser tube as the generator to give laser. It has 3 reflect mirrors to reflect the laser to one focus lens and focus to one red point so that to cut the work piece. Co2 laser machine has optional laser powers suitable for different thickness materials. The popular laser powers are 80W,100W,150W,300W.
Acrylic, also known as Plexiglas or Perspex, is a popular material for various applications due to its clarity, durability, and ease of processing. When it comes to cutting thick acrylic sheets, such as 25mm, the power of the CO2 laser cutting machine is a critical factor. This blog post will discuss the laser power considerations and the process involved in cutting 25mm acrylic with a CO2 laser cutter.
There are 2 laser powers can cut 25mm acrylic:
150W
300W
Following are the differences between 150W and 300W:
150W cuts 25mm acrylic at speed 1-2mm/s, 300W cuts 25mm acrylic at speed 6-7mm/s.
About the prices, the price for 150W co2 laser cutter is around USD5000 to USD6000, the price for 300W co2 laser cutter is around USD9000 to USD12000.
The price also depend on the working size and laser tube brands.
3. 150W laser tube can be equipped on the machine with working size 1300mm*900mm whole 300W laser tube can be equipped on the machine with working size both 1300mm*9000mm and 1300mm*2500mm. That is because 300W laser tube is bigger。
1. High Power Laser
Cutting through 25mm acrylic requires a high-power CO2 laser to ensure clean and efficient cutting. The exact power needed can vary based on the machine's design and the acrylic's quality, but generally:
Low to Medium Power Lasers (less than 100W) are not suitable for cutting 25mm acrylic.
High Power Lasers (150W to 200W) are more appropriate for cutting thicker acrylic without compromising on quality.
2. Laser Quality
The quality of the laser beam is crucial for achieving a clean edge. A well-collimated and focused beam will provide a better cut.
3. Cutting Speed
Higher power allows for faster cutting speeds, but the speed must be balanced with the laser power to avoid overheating the material or causing stress cracks.
4. Assist Gas
The type and pressure of the assist gas can affect the cutting process. Nitrogen is often preferred for acrylic to prevent oxidation and discoloration.
Material Preparation: Ensure the acrylic sheet is clean and free of any contaminants that could affect the cut quality.
Machine Setup: Adjust the laser power, speed, and assist gas settings according to the manufacturer's recommendations for cutting 25mm acrylic.
Cutting Path: Define the cutting path in the machine's control software, considering the thickness and any potential for internal stress.
Cutting Execution: Start the cutting process and monitor the machine to ensure the cut is clean and without errors.
Post-Processing: After cutting, the edges may need to be polished or smoothed to remove any residual heat marks.
Material Quality: High-quality acrylic will yield better cutting results.
Laser Settings: Proper settings are essential for achieving a clean and precise cut without causing damage to the acrylic.
Safety: Always follow safety guidelines when operating a laser cutter, including wearing appropriate protective gear.
Cutting 25mm acrylic with a CO2 laser cutter requires a high-power laser, typically in the range of 150W to 200W, to ensure a clean and efficient cut. By understanding the power requirements, cutting process, and considerations, users can successfully incorporate thick acrylic into their projects with a high-powered CO2 laser cutter.
For professionals in industries such as signage, display, and fabrication, a high-power CO2 laser cutter is an invaluable tool that can deliver high-quality results for cutting thick acrylic sheets.
