Custom laser cutting machine

Types of Custom Laser Cutting Machines

Custom laser cutting machines are sorted into two main types, the CO2 laser cutting machine and the fiber laser cutting machine. Each of the two types has unique features, strengths, and applications. They are described as follows:

• CO2 Laser Cutting Machine:

The CO2 laser beam is generated within the laser resonator using a mixed gas that comprises carbon dioxide, helium, and nitrogen. The laser beam is then delivered to the cutting head through a system of mirrors, which focuses it onto the material to be cut. The focused laser beam heats, melts, and vaporizes the material, creating a clean and precise cut. CO2 laser cutting machines are ideal for cutting non-metal materials such as wood, acrylic, glass, leather, and plastic. They offer high precision and can cut through thick materials. CO2 laser cutters are also available in two types, the galvanometer-based (galvo) laser and the gantry-based laser. The galvo-based laser is usually more efficient and faster than the gantry-based laser but has a limited work area, while the gantry-based laser is suitable for cutting large materials like metals.

• Fiber Laser Cutting Machine:

Fiber laser cutting machines use a solid-state laser generator to produce a laser beam that is delivered through a fiber optic cable to the cutting head. The laser beam is then focused onto the material to be cut, where it heats and melts the material, creating a precise and clean cut. Fiber laser cutting machines are mainly used for cutting metal materials such as steel, aluminum, brass, and copper. They are known for their high-speed cutting capabilities, precision, and efficiency. Fiber laser cutters are available in different power levels to suit various cutting applications. The lower power options are suitable for thin materials, while the higher power options can cut through thicker metals. Fiber lasers are also available in different configurations, such as open-bed machines, tube cutting machines, and compact fiber lasers.

Specifications and maintenance of custom laser cutting machines

The following specifications of custom laser cutting machines can be used to meet the unique demands of different industries and materials.

• Working area

It is the maximum dimension of the material that a laser cutting machine can process. The working area of a laser cutting machine is usually presented in length by width, such as 1300mm x 2500mm. Custom machines can be designed with working areas tailored to specific material sizes and industry needs.

• Laser power

Laser power is the amount of energy released by the laser beam, affecting cutting speed and thickness. Laser cutting machines use different units of power, usually ranging from tens to hundreds of watts. For example, cutting machines with 300W or 500W laser powers are suitable for precise cutting of thin materials, while those with 1000W or higher laser powers are better for thick materials. The laser power of a custom laser cutting machine can be adjusted to suit specific material types and thicknesses.

• Cutting speed

The cutting speed of a laser cutting machine refers to how quickly the laser beam moves across the material during the cutting process. It is usually measured in millimeters per minute. The cutting speed of the machine can vary depending on the material being cut and the thickness of the material. For instance, a typical laser cutting machine may have a speed of 1000 to 4000 mm per minute for metal, depending on the type and thickness of the metal. The cutting speed of a custom laser cutting machine can be fine-tuned to achieve optimal cutting results for specific materials.

• Positioning accuracy

Positioning accuracy refers to the ability of a laser cutting machine to precisely locate the cutting point on the material. It is usually measured in millimeters and indicates the machine's level of precision. The positioning accuracy of a laser cutting machine is determined by the control system and optical components. Typical laser cutting machines have a positioning accuracy of +/- 0.03 mm. Custom machines can be designed with higher accuracy to meet specific precision requirements.

• Maintenance

Proper maintenance is essential to ensuring the functionality and longevity of a custom laser cutting machine. Regular maintenance includes but is not limited to the following items.

• Optical system

Check the optical components, including mirrors and lenses, for any damage or contamination. Clean the optical surfaces with a gentle, non-abrasive cleaner to remove any debris or residue that may affect the laser beam's quality.

• Gantry and guide rails

Inspect the gantry system and guide rails for any dirt, debris, or build-up. Wipe them with a clean, dry cloth and then lubricate the guide rails to ensure smooth movement and precise positioning.

• Laser tube and power supply

Examine the laser tube for any signs of damage or wear. Check the power supply connections and cables for loose connections or damage. Calibrate the laser power and energy settings, and ensure that the cooling system is functioning correctly to maintain proper temperature and humidity.

• Safety precautions

Always follow safety guidelines when performing maintenance on a laser cutting machine. Ensure the machine is powered off before conducting any maintenance. Use appropriate personal protective equipment, such as safety glasses and gloves, to prevent injuries.
