Fiber Cutting Laser Machine for Aluminum Processing

Laser cutting machines are widely used in the metal processing industry, including the cutting of aluminum alloy materials. Fiber cutting laser machines are widely used in cutting aluminum alloy materials.

1. Advantages of Laser Cutting Aluminum

Laser cutting of aluminum alloys is characterized by high precision, high efficiency and flexibility.

• Thin cutting seam: The cutting seam of laser cutting aluminum plates is generally 0.1mm-0.2mm.
• Smooth cutting surface: The cutting surface of laser cutting aluminum plates is free of burrs and slag.
• Small thermal deformation: The cutting seam is thin, the speed is fast, and the energy is concentrated, so the heat transferred to the cut material is small, and the deformation of the material is also very small.
• Save materials: Laser processing uses computer programming, and laser equipment can cut aluminum plate workpieces of different shapes into material sets, improve the material utilization rate of aluminum plates, and save a lot of material costs.
• How thick the aluminum plate can be cut depends mainly on the power of the laser generator. Generally, the thickest 6000W can be cut to 16mm, and 4500W can be cut to 12mm.

2. Application Industry

Aerospace: Cutting of structural parts, fuselages and other components of aircraft.
Automobile manufacturing: Cutting of aluminum alloy parts such as automobile bodies, chassis, interior trims, etc.
Electronics industry: Cutting of electronic equipment housings, radiators and other aluminum components.
Architecture and decoration: Cutting of aluminum alloy doors and windows, curtain walls, decorative panels, etc.

3. What is the Price of an Aluminum Fiber Cutting Laser Machine?

The price of a laser cutting machine suitable for cutting aluminum ranges from US$20,000 to US$100,000. The specific price needs to be determined according to the brand configuration, and the price is different for different cutting materials.
The following factors should also be considered when purchasing a laser cutting machine:
Configuration: Including the configuration of core components such as laser cutting head, laser, motor, machine tool, CNC system, laser lens, etc. In particular, the quality and quality of the laser largely determines the basic price of the laser cutting machine.
Software system: A good laser company will have a professional technical department to develop and upgrade the relevant software system. A better software system means a higher price, but it can be better compatible with the hardware, perfectly matched, and maximize the function.
Accessories and consumables: These are also factors that affect the price of laser cutting machines.

4. What Should be Paid Attention to When Laser Processing Aluminum?

Copper, aluminum and its alloys are not easy to process by laser cutting due to their own characteristics (high reflectivity). Special attention should be paid when using aluminum plate fiber cutting laser machines.

4.1 Check the Material

Check whether the material has a lot of oil stains and dust, etc. If there are oil stains and dust on the surface of the material, it will greatly affect the quality of laser processing. When we are feeding and cutting, be sure to check whether the surface of the material is clean.

4.2 Use a Fiber Cutting Laser Machine with Appropriate Power

The size of the laser power determines the range of materials that the equipment can process, but the higher the power, the better. When cutting aluminum, aluminum needs to choose the appropriate power because of its low boiling point, low laser absorption rate, high thermal conductivity, high expansion coefficient and other characteristics.

4.3 Set the Correct Cutting Parameters and Cutting Speed

The main parameters of laser cutting are: feed speed, cutting head height, laser pulse frequency. The correct cutting parameters can make the cutting burr-free, accurate and product quality better.

4.4 Use Appropriate Auxiliary Gas

The auxiliary gas has two main functions: one is to blow away the residual waste slag to achieve the best cutting effect; the other is to use the gas to chase the metal slag while protecting the lens to prevent the slag from sticking to the lens and affecting the cutting quality.

5. What Types of Laser Cutting Machines are used for Aluminum Material Cutting?

Fiber Cutting Laser Machine

Fiber laser cutting machine is one of the most commonly used laser cutting equipment at present, with the characteristics of high efficiency, high precision and low energy consumption. It can be used to cut thin to medium-thick aluminum plates, can achieve fast cutting, and the cutting surface is smooth.

Carbon Dioxide Laser Cutting Machine

CO2 laser cutting machine uses carbon dioxide gas as the laser medium and generates laser by exciting the gas through electric current. After the laser beam is focused by the mirror, it can produce a high-energy density beam to cut the material.

The price of carbon dioxide laser cutting machine is relatively low, and the laser generator has high power. Black light-absorbing material can be coated on the aluminum plate to prevent reflection from burning the lens or laser head.

Solid-State Laser Cutting Machine

Solid-state lasers can also be used for cutting aluminum materials, suitable for some specific applications. At present, the output power of most products is below 600 watts. Due to the low output energy, they are mainly used for stamping, spot welding and cutting thin plates. The advantage of solid-state lasers is their high energy density, which is suitable for certain special cutting needs.

Summary

Fiber cutting laser machines have significant advantages in aluminum processing and can meet the high requirements of modern manufacturing for precision and efficiency. Choosing appropriate equipment and cutting parameters can significantly improve production efficiency and product quality.
