What is CNC Fiber Laser Cutting Machine
CNC (Computer Numerical Control) laser cutting is a laser cutting technology that utilizes a high-power laser beam guided by computer instructions to cut or engrave materials.
Benefits of CNC Fiber Laser Cutting Machine
Higher quality edges
The non-contact nature of laser cutting reduces the chance of mechanical distortion, resulting in cleaner edges with little to no burring.
Narrower kerfs
Compared to traditional cutting methods, CNC laser cutters produce a much smaller cut width (kerf), which allows for intricate cuts and maximizes material usage.
Smaller heat-affected zone (HAZ) and less material distortion
As lasers produce a smaller HAZ, there is less chance of thermal distortion of the material.
Less contamination and waste
The precision of the CNC laser cutter results in less waste material, and since it’s a contactless process, there’s reduced risk of material contamination.
Less maintenance required
CNC laser cutters often require less maintenance than their mechanical counterparts due to their non-contact nature.
Less repair costs
Fewer mechanical parts mean there are fewer components that can wear out or break, thus reducing repair costs.
Greater operator safety
The operation of a CNC laser cutter is generally automated and enclosed, reducing risks to the operator compared to manual cutting methods.
Types of CNC Fiber Laser Cutting Machine
Carbon dioxide (CO₂)
CO2 laser cutters are some of the most common and versatile types of CNC fiber laser cutting machines. They use a gas mixture with a high concentration of carbon dioxide, electrically stimulated to produce a powerful laser beam. These machines are great for cutting, engraving, and boring a wide range of materials, including most metals and non-metals.
Fiber
Fiber laser cutters use solid-state lasers with an optical fiber infused with rare-earth elements as the lasing medium. Fiber laser cutting is known for its efficiency, precision, and excellent beam quality. Fiber lasers are particularly effective for cutting metals and are often used in industrial applications.
Neodymium-doped yttrium aluminum garnet (Nd:YAG, or YAG)
YAG laser cutters utilize a crystal as the lasing medium, doped with neodymium (Nd). These lasers are effective for engraving and cutting metals and ceramics, and can be used for welding as well. The YAG laser can generate high-power beams and can operate in both pulsed and continuous modes.
Based on axis
The axis of a CNC machine refers to the number of directions the cutting tool can move in. More axes allow for more complex shapes and intricate cuts.
● 2-Axis CNC laser cutting
A 2-axis CNC laser cutter operates in a flat, 2D plane. This machine can move its laser head horizontally (X-axis) and vertically (Y-axis), which is optimal for cutting flat sheet materials like metal and wood.
● 3-Axis CNC laser cutting
In addition to the capabilities of the 2-axis machine, a 3-axis CNC laser cutter can move its laser head up and down (Z-axis), providing a greater depth of cut. This is especially useful for engraving applications.
● 4-Axis CNC laser cutting
A 4-axis CNC laser cutter can perform all movements of a 3-axis machine, but also rotates the workpiece around one axis, usually the X or Y-axis. This additional rotation allows for the creation of complex geometries and shapes.
● 5-Axis CNC laser cutting
5-axis CNC laser cutters offer even more flexibility, with the ability to rotate the workpiece around two separate axes simultaneously. This offers a great deal of control and precision in creating multi-dimensional, intricate shapes.
● 6-Axis CNC laser cutting
The 6-axis CNC laser cutter is the most advanced, featuring all the capabilities of the 5-axis machine plus another rotational axis. This allows the machine to cut from almost any angle, delivering extremely complex and precise cuts.

How Does CNC Fiber Laser Cutting Machine Work
Here’s a generalized explanation of the CNC laser cutting process:
● A design is created using CAD (Computer-Aided Design) software.
● The CAD design is then converted into a CNC program using CAM (Computer-Aided Manufacturing) software.
● The chosen material is prepared and placed on the CNC machine’s work surface.
● The machine is then set up according to the specific cutting requirements.
● The CNC machine guides the laser beam along the programmed path, cutting through the material.
● As the laser cuts, the material is cooled to prevent overheating and aid solidification.
● After cutting, the parts are inspected for quality, and post-processing steps may be performed if required.
Process of CNC Fiber Laser Cutting Machine
Design and CAD/CAM programming
The process begins with designing the desired shape or pattern using computer-aided design (CAD) software. Once the design is complete, it is converted into machine-readable code using computer-aided manufacturing (CAM) software. This code contains the instructions that will guide the CNC machine during the cutting process.
Material preparation
The material to be cut, such as metal sheets, wood, acrylic, or other materials, is prepared and placed on the CNC laser cutting machine’s work surface.
Machine setup
The CNC machine is set up for the specific material and thickness to be cut. This includes adjusting the focal length of the laser, selecting the appropriate cutting parameters (e.g., power, speed, and gas pressure for assist gases), and ensuring the correct alignment of the material.
Laser cutting
Once the setup is complete, the CNC machine begins the cutting process. The focused laser beam is directed onto the material’s surface, rapidly heating it to the point of melting or vaporization. The high-energy laser cuts through the material along the programmed path, guided by the CNC instructions.
Material removal
As the laser beam moves along the programmed path, it melts or vaporizes the material. The molten or vaporized material is expelled from the kerf (the cut path), leaving behind the desired shape or pattern.
Cooling and solidification
As the laser cuts through the material, it generates a significant amount of heat. Cooling mechanisms, such as water or air jets, are often employed to prevent the material from overheating and to aid in solidification.
Quality inspection
After the cutting process is complete, the cut parts are inspected for accuracy and quality. Any imperfections or deviations from the intended design are assessed, and adjustments can be made if necessary.
Post-processing (optional)
Depending on the application, the cut parts may undergo additional post-processing steps, such as deburring, surface treatment, or assembly.
What Types of Materials Can be Cut Using a CNC Fiber Laser Cutting Machine
CNC fiber laser cutting machines are exceptionally versatile tools, capable of cutting a wide range of materials with a high degree of accuracy and repeatability.

● Composites: Composites like fiberglass and carbon fiber can be cut with a CNC laser, though special care is needed due to the risk of harmful particles.
● Stone: Laser cutters can engrave stone but cutting through is usually not possible due to the high thickness and hardness.
● Glass: Like stone, laser cutters are more commonly used to engrave glass rather than cut it.
Components of CNC Fiber Laser Cutting Machine
Fiber laser source
It is the most core component of fiber laser cutting machine, and it is also the “power source” for fiber laser cutting machine to realize cutting operation. Compared with other types of lasers, fiber lasers have the advantages of higher efficiency, longer service life, less maintenance, and lower cost.
Laser cutting head
The cutting head of the laser cutting machine is a laser output device, which consists of nozzle, focus lens and focus tracking system. The cutting head of the laser cutting machine will travel according to the set cutting track, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses, and different cutting parameters.
Servo motors
Servo motor refers to an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The high-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the laser cutting machine.
Water chiller
The chiller is the cooling device of the laser cutting machine, which can quickly and efficiently cool the laser source, laser head and other devices. The current chillers all contain input and output control device switches, as well as advanced functions of cooling water flow, high and low temperature alarms, and their performance is more stable.
Air cutting system

Air cutting is ecocomical than other gas cutting, the reason to use air cutting is to save gas consumption cost comparing to Nitrogen.
Host
The bed, beam, table, and Z-axis system of the laser cutting machine are collectively referred to as the host. When the laser cutting machine performs cutting, first put the workpiece on the bed, and then use the servo motor to drive the beam to control the movement of the Z axis. The user can adjust the parameters according to their own needs.
Control system
It mainly controls the machine tool, realizes the movement of X, Y, Z axis, and also controls the output power of the laser.
Stabilizer
Connected between the laser, CNC machine tool and the power supply system. Mainly play a role in preventing external grid interference.
