In the past, aluminum parts were cut using traditional methods: plasma cutting, water jet cutting, or even using old-fashioned hand tools. Although still used by some fabricators, these methods are slow and outdated and are not precise enough for many modern aerospace and military applications.

Laser cutting has changed the game. Modern laser-cutting equipment is “strikingly effective” and offers superior precision and efficiency over traditional cutting methods. If you’d like to learn more about how laser cutting works and its significance in modern manufacturing, you’ve come to the right place.

In this guide to laser cutting aluminum, we will: 

  • Break down traditional methods
  • Explain laser cutting
  • Dive into the advantages this method brings.

Overview of Traditional Aluminum Cutting Methods

In the past, traditional methods such as mechanical and manual processes were used to cut aluminum parts. Mechanical methods included sawing, drilling, and grinding, while manual processes involved using hand tools such as hammers, chisels, and files. These methods were widely used because they were affordable and required minimal investment in equipment and technology.

However, these methods had several disadvantages. They were time-consuming, imprecise, and often resulted in the waste of material. Additionally, they could only be used for simple shapes and designs, limiting their versatility and usefulness for complex aerospace and military applications.

Despite these limitations, these methods remained popular because they were established and trusted. Manufacturers and fabricators were used to working with these methods and did not want to invest in new and expensive technology. It was only with the advent of laser cutting technology that traditional methods were replaced by a more precise and efficient method.

What is Aluminum Laser Cutting?

Laser cutting is a fabrication process that uses a high-powered laser beam to cut through metals and other materials. This technique is highly precise and efficient, making it a common choice for industrial applications that need high levels of accuracy.

The process of aluminum laser cutting involves directing a high-powered laser beam onto the surface of the metal. The intense heat of the laser beam causes the metal to melt and vaporize, creating a clean, precise cut. This method is highly versatile, allowing for the creation of complex shapes and intricate designs with ease.

One of the primary benefits of laser cutting aluminum is its precision. The laser beam can focus to a very small point, which allows highly accurate and precise cuts that are error-free. Therefore, resulting in higher production rates, faster turnaround times, and less room for error.

Here at New Age Metal Fabricating (NAMF), we have been utilizing this technology for years thanks to its superior results. That is the reason we invested in sophisticated laser-cutting machines. They allow us to deliver higher levels of precision and quality. This reduces prototyping time and saves costs so that you can get the parts you need for your products.

Comparing Aluminum Laser Cutting with Traditional Methods

When it comes to cutting aluminum, laser cutting and traditional cutting techniques differ significantly in terms of accuracy, efficiency, cost-effectiveness, and environmental impact. Traditional methods like plasma cutting, water jet cutting, and hand tools are slow, imprecise, and can result in material waste.

On the other hand, laser cutting can create precise complex shapes and intricate designs, making it efficient. It is also faster than traditional cutting methods, resulting in higher production rates and faster turnaround times.

While laser cutting equipment can be expensive, it can ultimately save costs eventually by reducing prototyping time. Furthermore, laser cutting is a more environmentally friendly option, as it produces less waste and uses less energy than traditional cutting methods. The power of laser cutting is how our team of professionals here at NAMF has been able to deliver high-quality parts to the engineering, aerospace, and military fields.

The Advantages of Laser-Cutting Aluminum

Laser cutting has several advantages, including a high level of accuracy. It can cut aluminum with a precision of up to 0.003 mm, which is impossible to achieve using traditional techniques. Moreover, laser cutting is more cost-effective and efficient than traditional cutting methods. It eradicates the need for expensive tools, and reduces waste.

Hence, making laser cutting an environmentally friendly process. These advantages enable us to provide our clients with high-quality, accurate, and cost-effective aluminum-cutting solutions that meet their specific needs. Our cutting-edge laser technology and our knowledgeable workforce enable us to consistently deliver exceptional results.

Challenges and Solutions in Laser Cutting Aluminum

While laser cutting aluminum is a highly precise and efficient process, there are still some challenges that can arise during the cutting process. One common challenge is ensuring that the aluminum material is thoroughly prepared for cutting. This involves ensuring that the material is clean, flat, and free from any surface contaminants that could interfere with the laser-cutting process.

Another challenge is selecting the right laser-cutting parameters. Choosing the wrong laser power, cutting speed, or focus could be disastrous for both the part and the machine. These parameters can have a major impact on the quality of the cut, so it’s essential to decide the right settings for each specific application.

At New Age Metal Fabricating, we overcome these challenges by using advanced laser cutting equipment and highly skilled technicians. We work closely with our customers to figure out what they need and adjust our cutting methods to fit their needs.

If you’re considering laser cutting services, it’s essential to select a reputable provider with experience in cutting aluminum.
