This guide will provide an in-depth look into the world of laser metal cutting machines, covering their types, materials, technical parameters, applications, cost factors, safety guidelines, innovations and trends.
Types of Laser Metal Cutting Machines
Laser metal cutting machines are widely used in the field of metal processing and can be divided into several different types according to different laser emission media and working principles.
Below, we will introduce four common types of laser metal cutting machines: fiber laser cutting machines, CO2 laser cutting machines, YAG laser cutting machines, and solid-state laser cutting machines.
Fiber Laser Cutting Machines
What is a fiber laser cutting machine? A fiber laser cutting machine is a kind of metal processing equipment that uses a fiber laser as a cutting tool.
It uses a fiber laser as the laser emission source. By focusing the laser beam onto the surface of the workpiece, it generates a high temperature on the surface of the workpiece, thereby achieving the cutting of metal materials.
Fiber laser cutting machines have high precision and efficiency. On one hand, because the fiber laser cutting machine uses laser technology, it has high positioning accuracy and cutting accuracy, and can achieve precise cutting of metal materials. On the other hand, fiber laser cutting machines have fast cutting speed and high work efficiency, and can meet the needs of mass production.
They are suitable for high-speed cutting of thin plates and are widely used in metal processing, electronic equipment manufacturing, and other fields.
CO2 Laser Cutting Machines
CO2 laser cutting machine is a device that uses a laser beam generated by a CO2 gas laser to cut materials. It focuses the laser beam onto the workpiece surface through an optical system, causing local melting or vaporization of the workpiece surface to achieve cutting of metal materials.
CO2 laser cutting machines have the characteristics of fast cutting speed, good cutting quality and large cutting thickness. They are suitable for cutting various metal materials (including stainless steel, aluminum alloy, copper, etc.), and can also cut some non-metal materials (such as plastic, wood, etc.).
They are suitable for cutting medium-thick plates and are widely used in metal processing, automobile manufacturing, electronic equipment, and other fields.
YAG Laser Cutting Machines
YAG laser cutting machine is a device that uses the laser beam generated by the solid YAG (Yttrium Aluminum Garnet) laser to cut materials.
The YAG laser transmits the laser beam to the cutting head through the optical system, and then focuses the laser beam onto the workpiece surface through the lens, causing local melting or vaporization of the workpiece surface to achieve cutting of metal materials.
YAG laser cutting machines have the advantages of high cutting precision, fast cutting speed, and good cutting quality. They are suitable for fine cutting and engraving of metal materials, such as stainless steel, aluminum alloy, copper, etc.
Solid-State Laser Cutting Machines
Solid-state laser cutting machines are efficient and accurate metal cutting equipment. They use laser beams generated by solid-state lasers to cut metal materials (including stainless steel, aluminum alloys, copper, etc.).
Solid-state lasers produce a high-energy laser beam by converting electrical energy into light energy, which can generate high temperatures on the metal surface, thereby melting or vaporizing the metal material for cutting purposes.
Due to the high energy conversion efficiency and stability of solid-state lasers, solid-state laser cutting machines usually have higher cutting speeds and lower energy consumption. They can handle high speed cutting of thick plates.
In general, different types of laser metal cutting machines have certain differences in working principles, cutting speed, cutting quality, etc. Therefore, when choosing a laser metal cutting machine, users should choose the appropriate type according to their needs.
The Versatility of Materials in Laser Metal Cutting Machines
Laser metal cutting machines use high energy density laser beams to cut metal materials. They have the advantages of fast cutting speed, high cutting quality, and easy operation.
Laser metal cutting machines can handle a variety of metal materials, including but not limited to the following common materials:
Stainless Steel
Stainless steel is a commonly used metal material. It has the advantages of corrosion resistance, high temperature resistance and high strength. Stainless steel is widely used in various fields because of its excellent properties.
Laser metal cutting machines cut stainless steel very well. Why say that? Because they can achieve high precision and smooth cutting edges. Moreover, the use of laser cutting can avoid material deformation or damage while maintaining the flatness and accuracy of the cutting edge.
The most important thing when cutting stainless steel is to control the cutting speed and focus position. Because the cutting speed is too fast, the cutting edge burrs or burns will be caused, and the focus position is not appropriate, which will affect the cutting quality and speed.
Therefore, when cutting stainless steel, it is necessary to adjust the cutting parameters reasonably according to the thickness and type of the material to ensure the cutting quality and efficiency.
Carbon Steel
Carbon steel is a common structural material composed of elements such as carbon and iron and has good workability and mechanical properties.
Laser metal cutting machines can cut carbon steel with high speed and high precision. By adjusting parameters such as laser power, cutting speed and focus position, precise cutting of carbon steel plates of different thicknesses and shapes can be achieved.
Whether it is for thinner carbon steel sheets or thicker sheets, laser cutting machines can provide high-quality cutting results. This flexibility makes laser cutting technology widely used in carbon steel processing.
Aluminum
Aluminum is a lightweight metal material with good thermal conductivity. Laser cutting of aluminum materials is one of the very common applications.
Due to the high thermal conductivity of aluminum, a high-power laser is required during laser cutting to ensure the cutting effect. This is mainly because high thermal conductivity will cause the laser beam to be affected by greater thermal diffusion during the cutting process. Therefore, it is necessary to use higher power lasers to increase energy density and achieve better cutting results.
The laser cutting machine has a very good cutting effect on aluminum and can achieve high-speed and high-precision cutting. It is suitable for aluminum plates of various thicknesses (thin, medium-thick, and thick aluminum plates) and shapes (curved aluminum plates, special-shaped aluminum plates, etc.).
Brass
Brass is a yellow metal alloy consisting primarily of copper and zinc. It has excellent electrical and thermal conductivity, as well as good processing properties.
Due to the material properties of brass, laser cutting brass may require some special cutting parameters and techniques. For example, proper adjustment of laser power, cutting speed, and gas assist can result in high-quality cuts in brass.
Titanium
Titanium is a metallic material with excellent corrosion resistance and strength-to-weight ratio.
The main reason why laser metal cutting machines can cut titanium is that the high energy density of the laser is compatible with the characteristics of titanium. Titanium has a high melting point and thermal conductivity, requiring a high-power laser to cut effectively.
The non-contact and high-precision nature of laser cutting makes it one of the ideal processes for cutting high-strength, high-temperature metals such as titanium.
In addition to the above common metal materials, laser metal cutting machines can also cut some special metal alloys and materials, such as tungsten, cast iron, nickel alloys, etc., with strong adaptability and versatility.
Key Technical Parameters of Laser Metal Cutting Machines
Laser metal cutting machine is an important equipment in the field of modern metal processing. Key technical parameters have a great influence on the performance and efficiency of laser metal cutting machines, including cutting thickness, cutting speed, laser power and working area, etc.
Below, we will introduce these four key technical parameters of laser metal cutting machines in detail:
Cutting Thickness
The cutting thickness of the laser metal cutting machine refers to the maximum thickness of the metal material that it can effectively cut.
The cutting thickness of low-power laser metal cutting machines is typically in the range of a few millimeters to roughly twenty millimeters, making them appropriate for thin metal materials. Thick metal materials can be processed using high-power laser metal cutting machines, with cutting thicknesses up to tens of millimeters.
It should be noted that the cutting thickness is not thicker, the better. Why say that? This is due to the possibility of decreased cutting speed and lowered cutting quality as metal sheet thickness rises.
Therefore, when choosing a laser metal cutting machine, it is necessary to choose the appropriate model and power according to the actual cutting needs and material thickness.
Cutting Speed
The cutting speed of a laser metal cutting machine refers to the cutting length that the cutting machine can complete per unit time, usually expressed in millimeters per minute.
Cutting speed is affected by many factors, including laser power, type and thickness of metal material, gas assist conditions, etc. For example, for the same laser power, thinner metal materials will be cut faster, while thicker metal materials will be cut slower.
Therefore, in practical applications, these factors need to be considered comprehensively according to the specific situation to determine the appropriate cutting speed and other process parameters.
Laser Power
Laser power is a very critical parameter for laser metal cutting machines. Because the laser power determines the energy density of the laser beam. And this will directly affect the speed and quality of cutting.
Typically, higher laser power means faster cutting speed and greater cutting depth. On one hand, fast cutting speed can improve the production efficiency of products, which is very important for mass production and applications that require high efficiency.
On the other hand, a greater cutting depth means that the laser cutting machine is able to cut thicker metal materials. This gives it a wider range of applications in industry.
Therefore, when selecting a laser metal cutting machine, it is necessary to select the appropriate laser power according to the processing requirements and material thickness to achieve the best cutting effect and production efficiency.
Working Area
The working area is the largest working area that the laser metal cutting machine can cut. It is usually expressed in terms of length and width. For example, a laser metal cutting machine with a working range of 1500mm×3000mm can handle workpieces 1500mm long and 3000mm wide.
The size of the scope of work is also a critical factor. Because it will directly affect the application range and processing capabilities of the laser metal cutting machine. For example, if the machine has a larger working range, it means that larger workpieces can be processed. This can increase processing flexibility.
Therefore, when choosing a laser metal cutting machine, you need to choose the appropriate working range based on the expected workpiece size and processing needs.
