II. Fundamentals of Laser Cutting Technology

1. Principles of Laser Cutting Technology

Laser cutting technology uses a focused beam of high-energy laser light to irradiate the workpiece. This process rapidly melts, vaporizes, ablates, or burns the material, while a coaxial stream of high-speed gas (known as assist gas) blows away the molten or vaporized material, achieving precise thermal cutting.

2. Advantages of Laser Cutting

Laser cutting technology's advantages are not only reflected in its efficiency and multi-material compatibility, but also in its significant reduction of production costs. You can further compare the performance characteristics of different models by downloading our Brochures.

III. Comparing Features and Specifications

1. Types of Laser Cutting Machines

(1) Laser Source Classification

1) CO2 Laser Cutting Machines

CO2 lasers use a mixture of carbon dioxide gases as the active medium. Through gas discharge, the laser is generated, focused into a powerful spot to melt or vaporize material, and assist gas removes the resulting debris. The wavelength is typically 10.6μm, which is better absorbed by non-metal materials.

The purchase cost is lower than that of fiber lasers, but the photoelectric conversion efficiency is only 10%-15%. They also require regular replacement of laser gases and frequent maintenance and calibration of mirrors, leading to higher operational and upkeep costs.

2) Fiber Laser Cutting Machines

Fiber lasers use rare earth-doped fibers, such as ytterbium, as the gain medium. A semiconductor pump generates the laser, which is focused into a highly concentrated spot that instantly melts metal. High-pressure assist gas then removes the molten material for a clean, precise cut. The wavelength is about 1.06μm, which metals absorb more readily.

Although the initial investment is higher, fiber lasers typically offer a photoelectric conversion efficiency above 30%—and can reach up to 50%. They require no laser gases, have a maintenance-free optical path, consume less electricity, and have lower operating and maintenance costs.

If you are considering purchasing a fiber laser cutting machine, you can browse the Single Table Fiber Laser Cutting Machine to view specific models and their performance characteristics.

3) Solid-State Laser Cutting Machines

Nd:YAG Laser Cutting Machines:

These early solid-state lasers use neodymium-doped yttrium aluminum garnet crystals as the gain medium and operate at a wavelength of 1.064μm. Traditionally used for metal marking and thin sheet cutting, they have lower efficiency, beam quality, and reliability compared to modern fiber lasers and are being gradually phased out.

Disk Laser Cutting Machines:

These use thin-disk crystals (such as Yb:YAG) as the gain medium and operate at a wavelength of about 1.03μm. They combine some advantages of CO2 lasers’ beam quality with fiber lasers’ suitability for metal cutting. However, their complex structure and higher cost mean they hold a much smaller market share compared to fiber lasers.

For your reference, the following table summarizes these options:

In short, for metal cutting, a fiber laser cutting machine is the top choice, while for non-metal materials, a CO₂ laser cutting machine is preferred. Although fiber laser cutting machines require a higher upfront investment, they offer lower maintenance costs, making them a smart long-term choice.

(2) Classification by Mechanical Structure

1) Gantry-type Laser Cutting Machine

The crossbeam is supported at both ends by rails on either side, providing excellent rigidity. This design is ideal for large-format, high-precision, and heavy-duty cutting tasks.

2) Cantilever-type Laser Cutting Machine

Here, the crossbeam is supported on just one side, resulting in a compact structure and a smaller footprint. This type is suitable for medium-format processing and environments where space is limited.

3) Hybrid-drive Laser Cutting Machine

An optimized version of the gantry type, the key improvement lies in the X-axis drive: the cutting head’s movement along the crossbeam (X-axis) is handled by an independent drive system, separate from the Y-axis movement of the crossbeam.

For selecting the right model, refer to the table below:

2. Key Parameter Influences

(1) Laser Power

Laser power is the primary indicator of a laser cutting machine’s capability, directly determining the types of materials it can cut, the maximum thickness, and the cutting speed.

Generally, higher laser power means faster cutting speeds for the same material and the ability to cut thicker sections.

For example, here is a reference table showing the required power for processing various metal materials:

(2) Worktable Size

Laser cutting machines are typically identified by a combination of numbers, with common models including:

• Model : Effective work area of mm (length) x mm (width), suitable for standard sheet metal applications.
• Model : Effective work area of mm x mm, ideal for larger sheets or processing more parts in a single batch.
• Other common models: ( mm x mm), ( mm x mm), and so on.

The size of the worktable impacts both processing capability and efficiency. When selecting a worktable, consider two main factors: the machine must accommodate the largest workpiece you plan to process, and there must be enough space for the equipment itself and any auxiliary devices (such as exchange tables or loading/unloading systems).

(3) Cutting Precision

Cutting precision involves both positioning accuracy and repeatability.

• Positioning Accuracy: The error between the machine’s actual position and the target position.
• Repeatability: The consistency when the machine returns to the same target position multiple times.

Laser cutting offers much higher precision compared to traditional methods. Typically, fiber laser cutting machines provide greater accuracy than CO₂ laser models, making them the go-to option for high-precision work. Refer to the table below for positioning accuracy:

(4) Assist Gas

The most common assist gases in laser cutting are oxygen, nitrogen, and compressed air.

• Oxygen (O₂): An active gas that heats the material through a chemical reaction, enabling fast cutting speeds for thick carbon steel, though it will oxidize the cut edge.
• Nitrogen (N₂): An inert gas that prevents oxidation, producing bright, clean edges on stainless steel and aluminum—ideal for high-quality cuts and welding applications, but more costly.
• Compressed Air: The most economical choice, with results that fall between oxygen and nitrogen; there may be slight oxidation on the cut edge, making it suitable for applications where edge quality is less critical.

The general rule is: the thicker the material, the higher the required gas pressure.

(5) Degree of Automation

Automation in laser cutting machines refers to the integration of technologies such as automatic loading and unloading, intelligent control, and robotic collaboration, enabling unmanned, highly efficient, and low-intervention production processes. The degree of automation varies among different grades of laser machines, but mainstream automated laser cutting systems are mainly composed of the following:

1) Automatic Loading and Unloading Systems

These systems enable automated material handling, precise positioning, sorting, and conveying, significantly reducing manual labor.

2) CNC Control Systems

Modern laser cutting machines are typically equipped with CNC systems that automatically control the X, Y, and Z axis movements of the cutting head, ensuring high precision and repeatability in cutting paths.

CNC systems also allow for automatic adjustment of laser power, cutting speed, gas flow, and other parameters, enabling full-process automation.

3) Material Library and Production Line Integration

Automated laser cutting systems can be integrated with raw material warehouses, finished goods storage, and conveyor lines, achieving end-to-end automation from raw material input to finished product output.

This level of automation reduces labor costs, delivers excellent repeatability, and minimizes waste.

2. Comprehensive Consideration of Budget and Total Cost of Ownership (TCO)

Calculating Total Cost of Ownership (TCO)

When evaluating total costs, it's not enough to focus solely on the initial purchase price. A comprehensive TCO perspective should be adopted, encompassing:

• Initial Investment: Equipment price, shipping, installation, and commissioning fees.
• Operating Costs: Electricity, auxiliary gas, consumables (nozzles, protective lenses).
• Maintenance Costs: Routine servicing and potential repair expenses.

Total Cost of Ownership (TCO) is a financial model for evaluating all direct and indirect costs over the equipment's entire lifecycle, with the basic formula:

TCO = Initial Cost + Operating Expenses + Additional Cost – Resale Value

For equipment pricing and calculation details, refer to Laser cutting machine Pricing Guide.

An initially more expensive machine that operates efficiently, with low failure rates and long-lasting key components, may have a lower TCO than a cheaper unit with high ongoing costs.

Ⅴ. Purchasing Process and Final Recommendations

1. Clarify Core Requirements

Before purchasing a laser cutting machine, it is important to understand the parameters and clearly define your core requirements:

2. Brand Selection

International and domestic brands each have their advantages.

Foreign laser cutting machines feature mature technology, high precision, leading automation and intelligence, and stable operation. They are ideal for large-scale, high-precision, and complex processes, offering easy maintenance and long service life.

However, they come at a higher price, with significant initial and maintenance costs, and require substantial capital.

Domestic machines offer high cost performance, relatively affordable pricing, and are suitable for SMEs or batch production needs. They provide a wide product range, large processing formats, compatibility with various metals, fast after-sales service, and low maintenance costs.

However, there may be gaps in high-end technologies, extreme applications, and some core components compared to top international models. Their experience in ultra-high power, precision, or automation integration is somewhat limited, with slightly lower stability in some cases.

Selection advice:

• For scenarios demanding high precision and automation, international equipment is preferable—budget permitting.
• For those prioritizing cost-effectiveness, routine batch processing, or custom production, domestic machines are more suitable.

3. Supplier Evaluation Criteria

When choosing a laser cutting machine supplier, it is recommended to conduct a thorough evaluation based on four major aspects: technical capability, production capacity, after-sales service, and brand reputation:

4. Testing and Validation Process

(1) Insist on On-Site Sample Cutting

On-site sample cutting is the test of a laser cutting machine’s true processing capabilities. Relying solely on the “perfect” samples sent by the manufacturer is insufficient, as these are typically produced under ideal, optimized conditions using the best possible materials. It is essential for you to be present and conduct tests using the actual materials you use in your daily production.

Reasons:

1) Material Variability: Different suppliers and even different batches of the same metal can have subtle differences in chemical composition, surface condition (such as oil, rust, or oxidation), and internal stresses. These variations can directly affect the laser’s absorption rate and cutting performance, often requiring parameter adjustments.

2) Process Window Validation: By testing with your own materials, you can assess the equipment’s ability to adapt to material variations—effectively, the width of its “process window.” A high-quality machine should maintain stable cutting quality through simple adjustments, even when material properties fluctuate slightly.

3) Simulating Real Production Conditions: The testing process should closely replicate your actual production scenarios, including continuous cutting of plates with varying thicknesses, to evaluate the machine’s stability and consistency under real-world loads.

Key Indicators:

(2) Optimize the Demonstration Process

A device demonstration should be more than passive observation; it’s an invaluable opportunity to actively gather crucial data and gain a deeper understanding of the machine’s performance limits. Shift your role from that of a “spectator” to a “test engineer.”

Before the demonstration, clearly communicate your specific testing requirements to the manufacturer. Request that the operators program and cut using your own drawings and materials, rather than simply running their pre-set, flawless demo routines. During the demonstration, engage proactively with the on-site engineers and voice any questions you may have.
