Laser plate cutting machines feature high-powered and highly accurate laser beams that are designed to produce precision cuts and clean etches on a wide gamut of materials. These machines are usually used to cut materials in industrial manufacturing applications such as structural and piping materials along with metal plates. The laser beams on laser cutting machines are responsible for burning, vaporization, or melting excess material, resulting in precision-quality cuts.
How a Laser Plate Cutting Machine Works
In laser cutting, a part is placed onto a bed, where material is then etched or cut from a sheet using a laser. Here is a simple overview of the laser cutting process:
Power is adjusted based on the material being cut and the thickness of the sheet. A typical laser beam has a diameter of 0.1 - 0.3mm (power of 2-3kW.)
A CAD drawing is converted into a series of commands that can be interpreted by the laser cutting machine. This is usually done by the machine operator based on its standard working procedure.
A sheet of material is then cut to size, placed on the machine's bed workpiece is clamped onto the bench, making sure that the orientation is straight (not slanted).
The material is now cut or scored by the laser. The light is emitted from a resonator; this is an airtight glass tube composed of two facing mirrors and filled with diode activated gases. It's then emitted from the cutting head, where light from the resonator is focussed onto a curved lens, where it is focused into a single beam).
Multiple parts can be cut from the same sheet and will run on the same program.
The Main Advantages of Laser Plate Cutting Machine
Good Cutting Quality
The slit width is narrow (typically 0.1-0.5mm), high precision (general hole center distance error 0.1-0.4mm, contour size error 0.1~0.5mm), the surface roughness of the slit is good (general Ria is 12.5~25μm). And the slits are generally welded without secondary processing.
Cutting Speed is Fast
For example, the cutting speed of carbon steel with 2kw laser power, a thickness of 8mm is 1.6m/min; the cutting speed of stainless steel with a thickness of 2mm is 3.5m/min, and the deformation is extremely small.
Clean, Safe and Non-polluting, Greatly Improving the Working Environment of the Operators
Laser cutting is a non-contact optical thermal processing, known as the "universal tool that never wears out. "The workpiece can be tightly nested or nested in any form to make full use of the raw materials. Moreover, due to the non-contact processing, the distortion of the machined parts is minimized and the amount of wear is reduced.
Comparison of Laser Cutting and Punching
Previously, the sheet metal processing industry used traditional punching machines for stamping and later developed into CNC turret punch presses and composite machine tools. With the advancement of society, laser cutting technology has also been introduced into the metal processing industry, and it has become an advanced processing method for industrial plate cutting.

Components of Laser Plate Cutting Machine
Laser Generator
The laser generator is the heart of the laser-cutting machine. It generates the laser beam used for cutting and carving materials. Generators use laser media (such as gas mixtures or crystals) that are excited to higher energy states. When the laser medium returns to its normal state, it will emit photons and generate a laser beam. The quality of the laser beam (its power and focus) mainly relies on the design and quality of the generator.
Cutting Head
The cutting head is the place where the laser beam is emitted from the machine and interacts with the materials to be cut. It contains a focusing lens that can concentrate the beam to the point onto a small point on the surface of the material. The strong energy produced by the focusing laser beam makes the material evaporate, thus forming a notch. The cutting head usually is equipped with a height follower system that maintains a constant and optimal distance between the cutting head and the material.
CNC Controller
The CNC controller is the brain of the laser-cutting machine. It explains CAD (computer assistant design) data and transforms it into accurate mechanical movement. This makes laser-cutting machine cut and engraves complex shapes precisely. The CNC controller also manages other machine parameters, such as power output, cutting speed, and auxiliary gas flow rate.
Assist Gas System
Assist gas system plays an important role in laser cutting process. It transports airflow (usually oxygen, nitrogen, or compressed air) at the cutting point. Assist gas is beneficial to blow away melted materials, cool the cutting area and impacts the quality of cutting edge. The choice of assist gas and its pressure depends on the type of materials being cut.
Material thickness and type
Consider the thickness and type of material that needs to be cut. Some laser plate cutting machines can only handle thin materials, while others can cut thicker materials up to 30mm or more. Also, some machines are better suited for cutting certain types of materials, such as metals or plastics.
Laser power
The power of the laser is an important factor in determining the speed and precision of the cutting process. Generally, the higher the wattage of the laser, the faster it can cut through materials.
Cutting speed
The cutting speed of the machine should also be considered. Faster cutting speeds can significantly improve production rates, but may come at a higher cost.
Bed size and capacity
The bed size and capacity of the machine will determine the maximum size and weight of the materials that can be cut. It is essential to choose a machine with a bed size that can accommodate the size of the materials you need to cut.
Accuracy and precision
The accuracy and precision of the machine are also crucial factors to consider. The machine should be able to cut intricate designs with precision and accuracy without creating any distortions or rough edges on the final product.
Ease of use
Choose a machine that is user-friendly and easy to operate. The software should be intuitive and easy to navigate. The cutting process should also be easy to set up, quick, and efficient.
Maintenance and support
Consider the maintenance requirements of the machine and the level of support provided by the manufacturer. Ensure that there is a reliable service team that can quickly address any issues that may arise.
How to Use Laser Plate Cutting Machine
Step 1: Safety precautions
Make sure you wear appropriate personal protective equipment (PPE), such as safety glasses and gloves, before operating the machine. Additionally, ensure that the machine is placed in a well-ventilated area to prevent any hazardous fumes.
Step 2: Prepare the material
Place the material on the cutting bed. Adjust the position and secure it in place using clamps or magnets to prevent it from shifting during the cutting process.
Step 3: Set the laser focus
Adjust the height of the laser nozzle to obtain the desired focus distance. The focus distance depends on the thickness of the material and the cutting requirements.
Step 4: Program the machine
Program the machine using the computer software to define the desired cutting path, including start and end points, cutting speed, and power. It is essential to select the correct material settings to ensure the laser provides accurate and clean cuts.
Step 5: Run the machine
Once the program is set up, ensure the machine is in the correct mode, i.e. cutting. Press the start button, and the machine will begin cutting the material according to the defined path and parameters.
Step 6: Remove the cut material
Once the machine has finished cutting, carefully remove the cut material from the bed. Use caution when handling the material, as the cut edges may be sharp.
Step 7: Clean the machine
After use, clean the machine thoroughly, removing any debris or residue on the lens, nozzle, and cutting bed. This helps to maintain the machine's performance and longevity.
