They use CO2 gases as a laser medium and generate lasers through electric current excitation. CO2 laser cutters are suitable for non-metal materials, like wood, plastic, and acrylic, and they also cut metals. Their wavelengths are about 10.6μm.

Motors are commonly used as drive devices, capable of precisely controlling the movement of the laser head in the X and Y directions.

Laser source directly decides the cutting performance and costs. Common laser sources include CO2 laser, fiber laser, and diode laser. CO2 laser cutters are suitable for non-metal cutting, fiber laser can handle metal cutting. When choosing a fiber source, you should consider laser power. The higher the power, the stronger the cutting speed and the handling capacity for material thickness.

The beginning of this article elaborates on the definition of laser cutting machines, their working principles, and detailed classifications to help you understand this machine and enhance your comprehension of the following content.

Controlled by the computer, laser beams can focus on a small area of the surface to melt and evaporate the materials and then use high-pressure gases to blow them off. In this way, the cutting is finished. Laser cutters, by virtue of high speed, accuracy and efficiency, are widely used in manufacturing.

Generally speaking, laser cutting machines by virtue of their high accuracy and efficiency and wide application secure a place in modern manufacturing. The invention of personal laser cutters brings new opportunities for laser cutter hobbyists and small enterprises.

They use a solid-state laser source, with its laser medium typically being neodymium-doped yttrium aluminum garnet (Nd: YAG). This machine is primarily used for cutting metal materials and is especially suitable for processing thinner metal sheets.

Motion system includes servo motor, guide rails, transmission devices, etc. It drives the cutting head to move along the designed paths. The accuracy and stability of the motion system directly decide the cutting quality and efficiency.

Laser cutting machines must be equipped with protective covers so as to avoid lasers damaging eyes and skin. The cover material, such as glass and acrylic, can block the working wavelength's laser. The protection requirements for 455nm blue diode lasers are lower than those for 10.6μm CO2 lasers.

Personal laser cutting machines offer unprecedented convenience and creative possibilities for DIY enthusiasts and small-scale manufacturers.

As the mind of a laser cutting machine, the control system accepts the cutting instructions and patterns inputted by the user and controls the output of the laser source and the movement of the motion system to achieve accurate cutting. The control system includes a CNC control system and dedicated software.

During cutting, the laser is fixed while the workpiece is moving. They are suitable for large materials or heavy industry.

CO2 laser tubes are the most commonly used light source for laser cutting machines, with a power range generally between 20-180W and a wavelength of 10.6μm. They are suitable for cutting non-metal materials such as wood, acrylic, fabric, etc. CO2 laser tubes have a relatively long lifespan but are large in size and require water cooling.

The size of cutting area decides the physical size of the machine, which also influences the storage location and workspace requirements. So you need to determine the maximum cutting area so as to choose the appropriate machine. Larger cutting area require more powerful laser source to ensure accuracy.

Diode laser modules have developed quickly in recent years, with power reaching 40w and a wavelength of 445-455nm. They are cheaper than CO2 laser tubes, smaller, and can be cooled by air. However, they are only suitable for cutting thin materials, and their speed is also slower than that of CO2 laser tubes.

Laser cutters produce small heat-affected areas, narrow silts, and high-quality cuts, which is a kind of contactless cutting method.

During cutting, the cutting heads controlled by CNC system will move along with the designed pathes, and at the same time, the cutting gases will spray out from the nozzle to blow the melt out so to form the cutting silts.

Before my introduction, I’d like to share a video with you to have an intuitive learning so as to digest the abstract concepts.

A focusing lens concentrates the laser beam onto a single point on the surface of the material to be cut, with zinc selenide being a commonly used material. The focal length of the lens generally ranges from 2-5 inches, with an aperture of 18-25mm^3. Diode lasers typically do not require mirrors; only a focusing lens is needed.

All in all, CO2 laser tubes cut faster and are suitable for production batches, but they require higher costs and high stand maintenance. While diode laser modules are cheaper and portable yet limited in cutting performance, so they are suitable for small batches of production and thin material cutting, which are favoured by laser cutting machine hobbyists.
