Safety Tips to Follow When Using CNC Laser Machine

Due to their increased shop productivity, CNC cutting sheet through laser machines is becoming increasingly popular. High-tech is very user-friendly and simplifies the lives of the employees. However, if someone doesn’t know what they are doing, they risk hurting themselves. Every worker should know the following safety precautions while CNC sheet cutting via CNC laser machine.

How does CNC laser cutting work?

CNC laser cutting is a thermal-based, non-contact method. A CNC laser cutter has a laser head with a nozzle and a laser focusing lens. This head and lens assembly focus a laser beam-column of extremely intense light through the nozzle onto the workpiece, melting and cutting it to the desired shape. Compressing gas is used in CNC lasers to cool the focusing lens and expel the evaporated metal from the workpiece while also passing through the nozzle that ejects the laser beam.

The heat density at a location on a metallic surface that is the focus of a strong laser beam increases, causing fast heating and partial vaporization of that point on the metal. Creating the appropriate customs forms and features is supported by CNC technology that coordinates the movements of this laser head and beams in the work area.

Five Safety Tips to Follow

Safety is of utmost importance when operating CNC laser machines as they can be very damaging if safety measures are not followed. Here are a few safety tips that should be followed while operating a CNC laser machine.

  • Never Leave Your Laser Unattended When Firing

Never Leave Your Laser Unattended When Firing

A laser cutter uses strong lasers that could catch fire in an accident or catastrophe. Accidents can occur when people use the cutter carelessly. The operator should monitor the operation whenever the machine is firing. There should be more than two operators working the machine because smaller projects take less time to complete, and larger ones can take several hours. If the first operator needs a break, the other operator can step in to continue inspecting the machine while it is firing. If you leave the laser cutter alone while firing, serious harm is dangerous.

  • Never Cut Material with Unknown Properties

Never Cut Material with Unknown Properties

The qualities of different materials vary so greatly that a laser cannot cut on all sorts of materials. For instance, some lasers are designed specifically for use with paper and wood, while others work well with toles and PVC. Avoid using the machine to cut just any material because doing so could harm or cause fumes to fill your workplace.

A ventilation system is included with laser cutting machines to ensure a smooth operation. Cutting materials like PVC and other polymers without a ventilation system can produce dangerous fumes that are fatal if inhaled. 

  • Always Keep A Clean Workshop

Always Keep A Clean Workshop

Laser cutting safety and cleanliness go hand in hand to reduce the danger of injury. Even though the material cut by laser cutters is entirely dissolved, there is still a risk of fire if the remaining scrap is allowed to remain in the catch-bin. The majority of people are unaware that little particles of chopped materials, like sawdust, in the air can catch fire and explode. The likelihood of accidents and other major laser cutting safety issues is decreased by maintaining a tidy and clutter-free workspace.

  • Be Informed


The operator should always know how to operate a laser cutter and engraver before using one safely. Before utilizing any equipment, the worker should read the user manual carefully to comprehend all safety considerations.

Knowing your equipment and reading its handbook can help you determine whether, for instance, eye protection is needed to operate your specific laser cutter safely. That being said, workplaces should display warning signs to alert people to safety hazards and adequately designate safety gear, such as fire extinguishers and eyewash stations close to the area with lasers. 

  • Be Alert


When using any gear, including lasers, it’s crucial to keep safety in mind constantly. Utilize best practices daily by emphasizing safety before beginning a project and avoiding carelessness when operating your laser cutting equipment. Be mindful of your surroundings and regular working routines. You can always contact the technical support of your supplier and conduct a check before using the laser. If there is ever any risk involved regarding the security of a specific substance or aspect of your machine’s operation, you should always have an emergency plan and look for potential safety hazards.

What is a CNC Laser Cutting? How it Works, Types & Advantages

A CNC laser cutter is a chunk of machinery that employs a concentrated, powerful laser beam to mark, chop, or engrave a material to design certain forms. Particularly when cutting delicate forms and tiny holes, its distinct design, and operation make it extremely accurate.

How does CNC Laser Cutting Works?


A CNC laser cutter has a laser head with a nozzle and a laser focusing lens. This head and lens assembly direct a laser beam—a column of extremely intense light—through the nozzle onto the workpiece, melting and cutting it to the required shape. Compressed gas is used in CNC lasers to cool the focusing lens and expel the evaporated metal from the workpiece while also passing through the nozzle that ejects the laser beam.

Types of CNC Laser Cutter


The sorts of lasers used in the machines account for the variations in CNC metal cutting laser cutters, and the type of laser affects the types of materials that the laser can cut and the thickness of those materials. Typically, a powerful laser is best for business purposes.

  • Gas Lasers/C02 Laser Cutters

CO2 that has been electronically stimulated is used to cut. Other gases like nitrogen and helium are included in the mixture that creates the CO2 laser.

Due to their effectiveness, low cost, and ability to cut and raster various materials, CO2 lasers are the most used laser cutters. These lasers can produce a smoother finish when used to cut thicker materials. A CO2 laser’s wavelength is 10.6 mm, and compared to a fiber laser of the same power, a CO2 laser has more energy to cut through thicker materials.

  • Crystal Laser Cutters

Beams made of nd: YVO (neodymium-doped yttrium ortho-vanadate) and nd: YAG is produced by crystal laser cutters (neodymium-doped yttrium aluminum garnet). They have shorter wavelengths than CO2 lasers, meaning they have a higher intensity, allowing them to cut through thicker and stronger materials. However, because of their enormous strength, their parts deteriorate quickly.

  • Fiber laser cutters

Fiberglass is used in this instance for cutting. The family of “solid-state lasers” includes disc lasers, and nd: YAG includes fiber lasers. The “seed laser” is the source of the lasers, which are then amplified using specific fibers. 

Fiber lasers are two to three times more energy-efficient than gas lasers, have no moving parts, and can cut reflective materials without caring about back reflections. Despite being roughly comparable to neodymium lasers, fiber lasers need less upkeep. Consequently, they provide a less expensive and durable option than crystal lasers. Both metal and non-metal materials are compatible with these lasers.

What Are the Advantages of Laser Cutting?


  • Flexibility

With laser cutting, there is no requirement to switch out tools for every cut. A similar setup can be used to cut numerous different forms from the same material thickness. Furthermore, complex cuts provide no issues.

  • Precision

Accuracy is one of the main benefits of laser cutting compared to other thermal cutting techniques. One can attain high precision without post-treatment with an accuracy of +/-0.1 mm. Such a high quality typically negates the need for further tolerances.

  • Repeatability

Parts nearly duplicates of one another are guaranteed with +/- 0.05 mm.

  • Speed

The laser cutter’s capability ultimately determines the precise advantage point. Compared to conventional mechanical cutting techniques, laser cutting is much faster, particularly when it comes to trickier cuts. Up to a thickness of around 10 mm, the laser outperforms conventional thermal cutting techniques like plasma or flame cutting in terms of speed.

  •  Automation 

Modern laser cutting technology is highly automated; thus, the job requires little human labor. While an expert machine operator still contributes significantly to the end product’s quality, the cutting speed and minimal manual labor requirement lead to cheaper costs than those associated with other cutting techniques. Even feeding systems and follow-up conveyors are standard equipment on many machines. Of course, such configurations result in a more expensive laser cutting machine.

  • Quality

Laser cutters only leave a little burr when properly set up. In many cases, it is not even essential to remove it. Yes, the material, its thickness, and other elements play a role. Having a limited heat-affected zone is an additional benefit. A narrower HAZ area produces more predictable and dependable parts as the microstructure and the HAZ change.

  • Contactless Cutting

Only the laser beam touches the material when cutting with a laser. Since there is no mechanical friction, tools won’t become worn out.

  • Versatility

One of the most significant features of laser cutting’s excellence is this. There are two ways adaptability shows up. Many different types of materials can be sliced using laser technology. Various metals, acrylic, MDF, wood, paper, and other materials are among them. We can configure different tasks onto a single computer. Of course, the power of your machine will determine your capacity to cut some of these materials.

Many laser cutters can do more than just cut things. Another application for these devices is laser branding. Additionally, there are numerous uses for marking when creating common products. The technique is also appropriate for a range of profiles.


CNC Cutting metal sheet services, whether it be steel, aluminum, brass, or nickel, are one of the most popular uses for lasers because they produce precise cuts and finishes. Laser cutting is widely used in the semiconductors, electronics, medical, aircraft, and transportation sectors. Lasers are also used to cut silicon, ceramics, and non-metals.
