What is Laser Cutting? How Does It Work?

Laser Cutting refers to the process that is used to cut materials and objects using a high-powered and extremely focused laser beam. 

With lasers, different processes are carried out, including laser engraving, laser marking, laser cutting, and other processes that include physical alteration of materials. But cutting is a quite different process that cuts the materials into pieces. 

what is laser cutting

The laser beams with intense power are encapsulated in the laser module and consist of electromagnetic radiation of a certain wavelength which can be invisible to the naked eye, such as infrared radiation in a CO2 laser cutter.

The beams are then passed through several bending mirrors and reflectors before converging at a single spot having a diameter in fractions of a millimeter through a convex lens.

laser beam principle

Accompanied by a fast-moving gas, usually Nitrogen or Oxygen, the highly focused laser beams come out from a nozzle and are directed by computer numerical control (CNC), which makes the process also known as CNC laser cutting. The computer program moves the laser head/module according to the requirement.

When the laser beams land on the material, the temperature of the material increases within milliseconds, causing sublimation, a process in which a material changes from a solid to a gaseous state without passing through the liquid state. 

The material then vaporizes, and the laser beams penetrate the object to cut it into the desired shape. The process can be completed in one pass if the laser beams are powerful enough; otherwise, several passes are needed.

In summary, laser cutting is a highly precise and efficient process that utilizes a focused laser beam to cut materials. The process involves the use of a highly-focused laser beam and computer numerical control (CNC), which work together to achieve the desired result.

Advantages of Laser Cutting

As explained above, laser cutting uses a high-powered laser beam to cut various materials and is directed by computer numerical control software, which achieve numerous advantages over traditional methods.

Laser Cutting Produces High-qualtiy Resutls

Due to the small size of the laser spot, high energy density, and fast cutting speed, laser cutting can achieve good cutting quality - precise and clean cuts.

The highly-powered and focused laser beam produces a very narrow kerf (cutting width) that vaporizes the material being cut, resulting in minimal material waste and producing a clean and smooth edge, with a surface roughness of only a few tens of micrometers.

Laser cutting can even be used as the final process without the need for mechanical processing, and the parts can be used directly.

Additionaly, the width of the heat-affected zone is very small, the properties of the material near the cutting edge are almost unaffected, and the deformation of the workpiece is small.

Laser Cutting Machines Process Automatically and Quickly

Laser cutting is an automated process. After you upload the design to the software and adjust the optimal laser beam's power, speed and focus settings based on the material being cut, guided by the control software, the laser beam moves quickly and efficiently, which can make thousands of cuts per minute.

Laser Cutting is Incredibly Versatile

Compared to other conventional processing methods, laser cutting has greater adaptability. 

First, compared to other thermal cutting methods, as a thermal cutting process, other methods cannot act on a very small area like a laser beam, resulting in wide cuts, large heat-affected zones, and significant workpiece deformation.

In addition, laser can cut non-metallic materials, while other thermal cutting methods cannot.

Laser cutting can cut a wide range of materials. Besides, the laser beam can be adjusted to suit different thicknesses, making it a flexible process that can be used for a variety of applications. 

Additionally, laser cutting machines can be used to create complex shapes and designs, engrave logos or designs, and even create 3D structures. 

This versatility makes laser cutting a popular choice in many industries, from automotive and aerospace to jewelry making and gift making, you can even start a small business selling laser-made products. 

Laser Cutting is an Non-contact Process

When laser cutting, the material being cut is not touched by the laser cutting machine, which means there is little risk of deformation or damage to the material, making it ideal for applications where precision and quality are critical.

Choosing a Laser Cutting Machine

Types of Laser Cutting Machines

Understanding the different types of laser cutters is crucial because each type is suitable for specific materials. There are four main types of laser cutters: CO2, crystal, fiber, and diode.

CO2 Laser Cutting Machines

In the CO2 laser, the laser beam is produced inside a sealed gas tube that contains a mixture of gas. The higher proportion of the gas is CO2. 

The tube has two electrodes connected at the ends. When a high potential difference is created between the electrodes, the positive nucleus and electrons start to move in particular directions. 

Due to the release of high energy from atoms, laser beams are produced from the tube. The beams are then reflected using mirrors and reflectors and converged using a convex lens.

The radiation emitted from CO2 lasers is invisible as it is in the infrared region. It is ideal for cutting and engraving non-metals, such as wood, plastic, paper, and fabric. 

Fiber Laser Cutting Machines

Fiber laser cutters are more advanced than CO2 laser cutters as they are newer and equipped with the latest technology. Consequently, they are very expensive.

Fiber lasers are based on seed lasers, in which a laser is generated using a bank of diodes and then amplified. For amplification, fiber lasers use glass fibers, so the resultant laser beams are 100 times more intense than CO2 laser beams. 

Due to the intense and high energy of the laser beams, they can easily cut metals, such as stainless steel, copper, and aluminum.

Fiber laser cutters are very efficient. They are nearly four times more efficient than CO2 laser cutters. The reason behind high efficiency is the use of glass fibers that convert 75% of the power into laser beams and reduce the power loss. 

Thus, fiber laser cutters are more powerful and intense than CO2 lasers of the same rated optical power. They also cut materials at a faster rate.

Diode Laser Cutting Machines

Diode lasers are also called semiconductor lasers because diodes are made of semiconductors. As the name suggests, diodes are used to create laser beams in this type of laser.

The diodes used for producing lasers are a bit different from common diodes. They have a special intrinsic layer that gives off high-energy photons, which are then amplified into a laser.

The working of these lasers is pretty simple. The diode banks emit laser beams which are then reflected using a reflector. 

If there are multiple diode lasers in a module, all the beams are converged using a convex lens. Once they pass from the convex lens, they are highly directional and focused, then they are ready to cut and engrave objects.

Diode lasers are quite popular and widely used these days. They are widely used for DIY projects and creating various products. 

They are excellent for cutting wood, opaque acrylic, and a few other materials. They can engrave wood, steel, leather, glass, rubber, acrylic, cardboard, ceramics, etc.

The materials for cutting are limited because these are not as powerful as other laser types. Usually, the laser optical power is 10W or lower; however, we have introduced a 40W diode laser module, which is the world’s most powerful diode laser module.

Typically, these are not suitable for translucent and reflective materials, such as metals. You cannot use them for metal cutting. However, they are excellent for cutting wood and acrylic for small projects. Due to low power, the speed is also lower than other laser types.

Diode lasers are very compact and lightweight. They are much more affordable and have a longer lifetime than other types of lasers, which is why they are quite common and preferred for startups and small businesses.
