What is Tube Cutting and How Does it Work?

What is Laser Tube Cutting?

Laser tube cutting involves using high-powered lasers to perform precision cuts, pattern detailing and custom shapes and designs on tubes made from various metals including aluminium, copper and stainless steel.

How Does Laser Tube Cutting Work?

Tube cutting can be achieved with two different types of laser technology – CO₂ powered and fibre lasers.

CO₂ lasers: For tube cutting, CO₂ lasers use a mixture of gas excited by electricity to generate a powerful infrared beam. These are suitable for most metals, but may have trouble with reflective materials.

Fibre lasers: Offering high precision for tube cutting, fibre lasers are ideal for reflective metals like aluminium and copper but are also suited for other metals too. Fibre lasers offer faster and more energy-efficient tube cutting than CO₂ machines and work by using optical fibres to amplify a laser beam.

Both types of machines and laser cutting techniques are utilised by our team at Central Profiles, meaning all manner of cutting requirements are facilitated.

The Laser Cutting Process – Step-by-step breakdown

The answer to what is tube cutting can be helped explained by the actual process.

1. Tube Placement and Alignment

The tube is securely positioned using advanced automation and rotary chucks to ensure proper alignment and prevent movement during cutting. More advanced machines will use sensors and cameras to detect position irregularities and for optimal accuracy.

2. Laser Beam Generation

A CO₂ or fibre laser generates an intense, focused beam directed through a nozzle. A CO₂ laser uses a gas medium, while the beam of a fibre laser is transmitted by optical fibres. Both machines will ensure clean and precise cuts, with the beam precisely controlled to focus on the cutting area.

3. Cutting and Material Removal

According to a programmed cutting path, the laser will melt, burn or vaporise the material and high-pressure assist gases, such as nitrogen or oxygen, will help remove any molten material. This results in a smooth edge and allows for intricate shapes, patterns and high-speed production with minimal distortion.

4. Cooling and Finishing

To prevent warping, the tube will undergo cooling after cutting; other finishing processes, such as surface treatments, can be applied to improve edge quality and prepare the tube for further welding fabrication or assembly.

Automation and CAD Integration

You wouldn’t build a new home or craft a structural component without an established design, so why would cutting tube profiles be any different? Before any laser cutting or finishes like powder coating take place, state-of-the-art software is utilised to achieve the desired finished cut product businesses are after.

This is known as computer aided design (CAD) or computer aided manufacturing (CAM) software. This innovative software is seamlessly integrated with laser tube cutting machines and processes, allowing for precise, automated production. Even the most detailed, intricate tube designs and patterns are designed in CAD software and then converted into laser machine-readable, automated instructions by CAM systems. With integrated software for laser tube cutting, the benefits include rapid prototyping, reduced setup times and minimal material waste.

Automation also extends to loading and unloading to further streamline production, and advanced nesting algorithms optimise material usage, while real-time monitoring enhances accuracy. Combining laser tube cutting with CAD and CAM software, manufacturers will achieve improved consistency, faster turnaround times and greater design flexibility.

What Are the Methods of Tube Cutting?

Each with its own advantages and limitations, tube cutting can be achieved via lasers and more traditional methods such as saw cutting, abrasive cutting and shearing. Laser cutting has emerged as the most popular and efficient out of these options, especially when working with metal alloys and materials. Let’s explore the other methods of tube cutting to see how they compare.

Laser Tube Cutting vs. Other Methods

Saw Cutting

One of the oldest and most traditional methods, saw cutting, involves utilising band saws or circular saws. This method is ideal for simple, straight cuts but is much slower than laser tube cutting and produces rough edges which often require secondary finishing. While tube cutting with lasers is low maintenance, saw blades will wear out over time, leading to higher maintenance and replacement costs as well as inconsistent cutting results.

Abrasive Cutting

Suitable for harder materials but generating excessive heat and debris, abrasive cutting uses high-speed grinding wheels to cut through metal tubes. This cutting method can lead to warping and high material loss, and it lacks the precision for intricate shapes many tube profiles require.

Waterjet Cutting

Able to handle various metal and non-metallic materials, waterjet cutting uses high-pressure (typically ranging from 30,000 to 90,000 psi) mixed with abrasive particles to cut tubes. While this method is great for cutting without thermal distortion, it is typically slower and less cost-effective compared to laser cutting technology.

Shearing and Punching

High-volume and repetitive cutting processes benefit from shearing and punching. Tubes are cut to a desired length using a shearing machine, and then holes are created using a punch tool. However, both these methods are often limited to straight cuts and basic shapes, not offering the flexibility and high-precision laser tube cutting brings to the table
