1. What is a laser cutting machine?

A laser cutting machine is a device that uses a high-powered laser beam to cut through various materials with precision. It operates by directing the laser beam onto the material, melting, vaporizing, or burning through it to create intricate cuts.

2. What is cutting speed of laser cutting machine?

The cutting speed of a laser cutting machine can vary depending on several factors, including:

Material Type: Different materials have different cutting characteristics, such as thickness, density, and thermal conductivity. These factors can influence the optimal cutting speed for each material.

Material Thickness: Thicker materials generally require slower cutting speeds to ensure proper cutting and avoid issues like excessive melting or heat-affected zones.

Laser Power: The power of the laser source used in the machine can affect the cutting speed. Higher laser power allows for faster cutting speeds, but the relationship between power and speed may vary based on the material being cut.

For 3KW laser, it can cut 3mm stainless steel at 6m/min while 12KW cut at up to35m/min

3. What gas does laser cutting machine use?

Oxygen (O2): Oxygen is often used when cutting materials such as carbon steel. The laser beam heats the material to its ignition point, and a stream of oxygen is then directed at the heated area to oxidize and remove the molten metal, resulting in a clean cut.

Nitrogen (N2): Nitrogen is commonly used for cutting materials that are sensitive to oxidation, such as stainless steel or aluminum. The nitrogen gas displaces the surrounding air, reducing the likelihood of oxidation during the cutting process and producing a high-quality, oxide-free cut.

Compressed air: Compressed air can serve as an assist gas, blowing away molten material from the cutting area. It helps to keep the cut clean and prevents debris from interfering with the laser beam. For high power laser such as 12KW, it can cut 10mm mild steel at 6m/min, which is about 200% faster than cutting with oxygen.

4. What materials can be cut with a laser cutting machine?

Laser cutting machines can cut through a wide range of materials, including metals (such as steel, aluminum, and brass), wood, acrylic, plastic, fabric, leather, and more. The specific capabilities may vary depending on the power and type of laser used.

5. What are the advantages of using a laser cutting machine?

Some advantages of laser cutting machines include high precision, versatility, minimal material wastage, fast cutting speeds, the ability to create intricate designs, and the capability to cut a wide range of materials. They also offer non-contact cutting, which reduces the risk of material distortion or damage.

6. What industries use laser cutting machines?

Laser cutting machines are used in various industries, including manufacturing, engineering, automotive, aerospace, architecture, jewelry making, signage, textile, and packaging. They are suitable for both industrial-scale production and small-scale applications.

7. What factors should be considered when choosing a laser cutting machine?

Important factors to consider include the type and thickness of materials you plan to cut, the desired cutting speed and precision, available power options, the size of the working area, maintenance requirements, and the reputation and support provided by the manufacturer.

8. What are the main types of laser cutting machines?

The main types of laser cutting machines are CO2 lasers, fiber lasers, and Nd:YAG lasers. CO2 lasers are commonly used for cutting non-metallic materials, while fiber lasers are more suitable for cutting metals. Nd:YAG lasers are versatile and can be used for both non-metallic and metallic materials.

9. What is the typical accuracy or precision of Alpha laser cutting machines?

The accuracy or precision of laser cutting machines can vary depending on factors such as the machine’s design, power, and the material being cut. Generally, laser cutting machines can achieve high levels of precision, with tolerances often ranging from 0.2mm to 0.05mm

10. Can laser cutting machines cut thick materials?

Yes, laser cutting machines can cut thick materials, especially when using high-power lasers. Fiber lasers, in particular, are known for their ability to cut through thick metal sheets with ease. However, the maximum thickness that can be cut will depend on the power of the laser and the type of material. Such as 12KW laser, it can cut up to 40mm mild steel, 30mm stainless steel and 25mm aluminum.

11. What is the maintenance required for laser cutting machines?

Maintenance requirements can vary depending on the specific laser cutting machine and its components. Regular maintenance will be done by machine operator, typically involves cleaning the optics, replacing consumable parts (such as nozzles and lenses), checking and aligning the laser beam, and ensuring proper ventilation and cooling. Annual maintenance will be scheduled and done by our service technicians.

12. What file formats are compatible with laser cutting machines?

Laser cutting machines commonly accept vector-based file formats such as DXF (Drawing Exchange Format) ,AI (Adobe Illustrator) and standard G code NC program . These file formats preserve the geometry and curves of the design and are easily translated into cutting paths for the laser cutting machine.
