FAQ Topics
Basic Questions
What is laser cutting and how does it work?
Laser cutting is a non-contact cutting process that uses a focused high-density laser beam to melt, burn, or vaporize material along a programmed cutting path. In metal fabrication, the laser beam is guided by a CNC system to create narrow, accurate cuts with smooth edges and minimal mechanical force on the workpiece.
What is a fiber laser?
A fiber laser is a high-power laser system that uses optical fiber as the active gain medium. The beam is generated and transmitted efficiently through fiber, making it suitable for industrial metal cutting applications that require high energy density, stable output, and efficient operation.
What is a fiber laser cutting machine used for?
A fiber laser cutting machine is mainly used to cut metal sheets, tubes, and profiles. It can also be used for creating patterns, holes, contours, and certain engraving effects on metal surfaces when configured with the correct CNC program and cutting parameters.
Accuracy, Thickness & Service Life
How accurate is a fiber laser cutting machine?
Fiber laser cutting can achieve high cutting accuracy with a narrow kerf and clean edge quality. Actual accuracy depends on machine structure, servo system, cutting head, material type, thickness, nesting program, and process parameters. For precision sheet metal fabrication, fiber laser cutting is widely used because it can produce consistent and repeatable results.
How thick can a fiber laser cut?
Cutting thickness depends mainly on laser power, material type, assist gas, cutting speed, and required edge quality. Higher-power machines can cut thicker metal sheets, while lower-power machines are more suitable for thinner sheet metal and precision parts. For an accurate recommendation, the material grade, maximum thickness, and production target should be confirmed first.
How long does a fiber laser cutting machine last?
Fiber laser systems are known for long service life and relatively low maintenance requirements. The actual machine life depends on laser source quality, working hours, cooling system condition, dust control, operator practice, and maintenance schedule. A well-maintained machine can support long-term industrial production.
Materials & Applications
What materials can a fiber laser cutting machine cut?
Fiber laser cutting machines are mainly used for metal materials, including carbon steel, mild steel, stainless steel, aluminum, copper, brass, galvanized steel, and other conductive metal materials. The cutting result depends on material thickness, reflectivity, surface condition, and machine power.
Can a fiber laser cutting machine engrave metal?
Yes. A fiber laser cutting machine can create engraved patterns or markings on metal surfaces when the machine is programmed for engraving or low-depth marking operations. However, for dedicated marking applications, a fiber laser marking machine may be more efficient.
Can a fiber laser cut wood?
Fiber laser machines are not normally recommended for cutting wood. Fiber lasers are designed mainly for metal processing, and the high-energy beam may burn or char organic materials. For wood cutting, a CO2 laser machine is usually a better choice.
Can a fiber laser cut plastic?
Fiber laser cutting is generally not recommended for plastic. Plastic can melt, burn, deform, or release smoke during laser processing. For plastic, acrylic, wood, leather, and many non-metal materials, CO2 laser systems are usually more suitable.
Operation & CNC Control
How does a laser cutting machine work step by step?
First, the material is placed on the machine worktable. Second, the cutting drawing is imported into the control system. Third, the operator sets the cutting parameters according to material and thickness. Fourth, the machine follows the programmed path and cuts the material automatically. Finally, the finished parts are removed and inspected.
How does a CNC fiber laser cutting machine work?
CNC means Computer Numerical Control. In a CNC fiber laser cutting machine, the cutting pattern is created in CAD/CAM or nesting software and then sent to the machine control system. The CNC system controls the motion of the cutting head and worktable according to the programmed path.
Can a fiber laser cutting machine cut complicated patterns?
Yes. With CNC control and proper nesting software, a fiber laser cutting machine can cut complex shapes, holes, slots, curves, decorative patterns, and custom sheet metal parts. This is one of the main reasons fiber laser cutting is widely used in modern fabrication.
Machine Selection
How do I choose the right fiber laser cutting machine?
Start with the materials you cut most often, the maximum thickness, sheet size, required cutting speed, production volume, budget, local voltage, and factory layout. For industrial users, it is also important to consider machine bed strength, laser source power, cutting head quality, control system, after-sales support, and spare parts availability.
What laser power should I choose?
The right laser power depends on your material and thickness range. Thin sheet metal can usually be processed with lower power, while thicker carbon steel, stainless steel, and aluminum require higher power for stable and efficient cutting. HALDEN can recommend a configuration after reviewing your cutting requirements.
Where can I buy a fiber laser cutting machine?
Fiber laser cutting machines can be purchased from professional laser equipment manufacturers and industrial machinery suppliers. HALDEN provides fiber laser cutting machine solutions for sheet metal processing, tube cutting, plate cutting, and customized metal fabrication applications.
Comparison & Advantages
Why are fiber laser cutting machines becoming more popular?
Fiber laser cutting machines are popular because they offer high speed, high precision, clean cutting edges, low noise, non-contact processing, lower consumable use, and broad metal compatibility. They are especially effective for modern sheet metal manufacturing and high-efficiency fabrication workshops.
What are the main advantages of fiber laser cutting?
The main advantages include fast cutting speed, high accuracy, clean edges, low maintenance, low consumable cost, CNC flexibility, and the ability to cut reflective metals such as aluminum, copper, and brass when the system is properly configured.
What is the difference between CO2 laser and fiber laser?
Fiber lasers are generally better suited for metal cutting, especially thin to medium-thickness metal sheets. CO2 lasers are often better for non-metal materials such as wood, acrylic, leather, and some plastics. Fiber lasers usually offer higher electrical efficiency, lower maintenance, and better performance on reflective metals.
What is the difference between fiber laser and YAG cutting machine?
Fiber laser cutting machines generally require less maintenance and offer better energy efficiency than many traditional YAG laser systems. Fiber laser systems are now more widely used in industrial metal cutting because of their stability, efficiency, and lower operating cost.
Limitations & Safety
What are the disadvantages of fiber laser cutting?
The main disadvantages are the higher initial machine investment and the need for correct configuration based on material and thickness. Fiber lasers are excellent for metal processing, but they are not the best choice for many non-metal materials such as wood, acrylic, leather, or plastic.
What are the risks of using a fiber laser cutting machine?
Fiber laser cutting involves high-power laser radiation, high temperature, assist gases, fumes, moving mechanical parts, and electrical systems. Operators must use proper safety procedures, protective eyewear, ventilation, machine enclosure, grounding, and regular inspection. Direct exposure to laser radiation can be dangerous, especially to the eyes.
What are the overall pros and cons of laser cutting?
The main pros are high precision, fast processing, clean edges, CNC flexibility, low mechanical stress, and the ability to cut complex shapes. The main cons are higher equipment cost, safety requirements, and the need to choose the correct machine type for the material being processed.
