Laser Cutting Machine
What is a laser cutting machine?
The laser cutting machine is a kind of CNC laser equipment. It uses CO2 laser or fiber laser beam to cut metal and non-metallic materials into 2D or 3D shapes and contours. CNC laser cutters are widely used in industrial manufacturing, school education, small businesses, home businesses, small shops, home shops, hobbyists, and craftsmen. The kits and parts of the CNC laser cutter includes a controller, frame, laser generator, power supply, laser tube, laser head, lens, laser mirror, chiller, motor, drive, cylinder, air compressor, air tank, Cold filter, dryer, dust collector, numerical control software and numerical control system. Laser cutting machine is also called laser engraving machine, CNC laser cutter, CNC laser cutting machine, laser CNC machine, laser cutter engraver, laser cutter and engraver, and laser cutter near me.
Compared with the traditional metal cutting machines or acrylic cutting machines, the laser machine belongs to non-contact processing. The laser head has no contact with the workpiece. And it will not scratch the surface of the workpiece during work. The wood laser cutter near me or the metal laser cutter uses an invisible laser beam to replace the traditional mechanical knife. Therefore, it has the characteristics of high precision, fast cutting, smooth cut, and low processing cost.
How does a laser cutting machine work?
The laser beam is a kind of light, which is produced by the transition of atoms (molecules or ions). However, the laser only relies on spontaneous emission for a short time. The subsequent process is completely determined by the excitation radiation. Therefore, the laser has a very pure color with no divergence direction. And it has extremely high luminous intensity and high coherence.
Under the control of the computer, the laser is discharged through pulses. Then the pulsed laser beam is transmitted and reflected through the optical path and is focused by the focusing lens group. A tiny, high-energy-density light spot is formed on the surface of the workpiece, and the focus is located near the surface of the workpiece. The workpiece melts or vaporizes at an instant high temperature. As a result, each high-energy laser pulse immediately sputters a small hole on the surface of the object. Under the control of the computer, the laser processing head dotting according to the pre-drawn graphics, thereby processing the object into the required shape.
As the laser beam moves relative to the workpiece, the material is finally cut to achieve the purpose of cutting. Different laser power can process different workpieces with different thicknesses. Generally speaking, thicker workpieces require higher laser power.
How about the main process method of the laser cutting machine?
1. Laser vaporization cutting
In the laser vaporization cutting process, the surface temperature of the material rises quickly, which can avoid melting. So part of the material vaporizes into steam and disappears, and the other part is blown away by the auxiliary gas flow from the bottom of the slit. To prevent material vapor from condensing on the slit wall, the thickness of the material must not greatly exceed the diameter of the laser beam. This processing cannot be used for materials that are not in a molten state, such as wood and certain ceramics.
2.Laer fusion cutting
In this method, the workpiece is partially melted and the molten material is sprayed out by airflow. Because the transfer of the material only occurs in its liquid state, the process is called laser fusion cutting. Laser fusion cutting can get a higher cutting speed than laser vaporization cutting. In laser fusion cutting, the laser beam is only partially absorbed. The maximum cutting speed increases with the laser power increasing and decreases with the thicknesses of the sheet and melting temperature rising.
The material is ignited under the irradiation of the laser beam and undergoes a fierce chemical reaction with oxygen. Next, it generates another heat source to further heat the material, which is called flame cutting. Its cutting rate is higher than that of laser fusion cutting. However, the incision is rough and the slit is wide, which is not conducive to processing precision models and sharp corners.
4.Control fracture cutting
For brittle materials that are easily damaged by heat, high-speed and controllable cutting is performed by laser beam heating, which is called controlled fracture cutting. The cutting process is: the laser beam heats a small area of the brittle material, causing a large thermal gradient and severe mechanical deformation in this area. Then it leads to the formation of cracks in the material. As long as a stable heating gradient is maintained, the laser beam can make cracks in any desired direction.
The Difference between Laser Cutting Machine and Traditional CNC Cutting Near Me
|Method ||Slit ||Precision ||Speed ||Deformation ||Cost |
|Laser cutting ||Very narrow ||higher ||slow ||Very small ||expensive |
|Plasma cutting ||wide ||high ||fast ||large ||cheap |
|Flame cutting ||Very narrow ||higher ||slower ||Smaller ||Very expensive |
|Water cutting ||wide ||high ||fast ||small ||expensive |
|Fusion cutting ||Very wide ||low ||slow ||Very large ||cheap |
From the above comparison table, we can see that the CNC laser cutter has the advantages of a narrow slit, high precision, and small deformation. And in the 1950s and 1960s, flame cutting was used as the main method for cutting medium and thick plates. After the 1970s, precision flame cutting and plasma cutting were promoted. To reduce the manufacturing cycle, CNC nibbling and electrical machining technology have been developed.

3 popular laser machine cutters recommendation
According to laser generators, the most common CNC laser cutting machine includes the fiber laser cutting machine, and CO2 laser cutting machine. The following is an introduction to the characteristics of the two CNC laser cutters and their respective market positioning.
Fiber laser cutting machine
A fiber laser cutter transmits the laser beam through the optical fiber. It has the features of high flexibility, fewer failure points, convenient maintenance, and fast processing speed. In addition, the photoelectric conversion rate of the fiber laser cutter is as high as 25%. So the advantages of fiber laser cutters are quite obvious in terms of electricity consumption and supporting cooling systems.
The wavelength of the fiber laser cutting machine is 1.064um, which is easily absorbed by metals. So it is also known as metal cutting machines, or metal laser cutting machines. As an emerging laser technology, a fiber laser cutting machine is far less popular than a CO2 laser cutter.

Features of laser cutting machine compared with traditional cutting methods
In the field of cutting, traditional cutting methods mainly include the blanking press or turret punch. The blanking press has a special cutting tool for each shape. While the turret punch has many small tools to punch out parts by cutting a limited number of hole sizes and some linear blades for the outer edge. However, the laser engraving machine for sale uses the laser beam to melt the materials in a non-contact manner. Therefore, laser equipment has many advantages compared with other cutting processes.
1.Low energy consumption.
A general blanking press or turret punching machine consumes a total of 50kW of power. It is equivalent to a 4kw laser system that usually uses a total of 10kW.
The blanking press has a large blade that can move up and down quickly to cut. It does not necessarily have a safety function to prevent the hand from getting stuck. Due to the high level of automation, laser wood or metal cutting machines can complete sheet or tube cutting automatically. It greatly decreases the human intervention during the cutting process and effectively protects the operator’s safety. Besides, the laser equipment with a protective cover can protect not only the operator’s safety but also the environment.
3.Save raw materials.
The so-called saving of raw materials is a more efficient use of materials. Since the cutting tool needs to cut the materials on both sides, at least a 12.7mm frame is left. For the laser cutting machine, if the parts have a common profile, they can be cut with a single cut without waste.
The blanking die can only be cut by exceeding the maximum tensile strength of the material. While the CNC laser cutting machine near me can cut any strength material at a high speed and high precision.
Blanking presses or turret punches have very expensive parts. And maintenance and replacement of such parts require a lot of costs. However, the laser sheet metal cutting machine or engraving laser machine requires less maintenance.
The traditional production line is equipped with a fixed design tool for each part. If the nature of the part changes, the design change is limited to the available tools. Otherwise, you must buy new tools and replace the available slots on the turret. The CNC laser equipment near me adopts programming technology, and the processing is very flexible and convenient. You can use the metal fiber laser cutting machine or CO2 laser to engrave and cut various kinds of products without changing any mechanical parts.
7.Fast processing speed and high production efficiency.
The blanking press takes 30 minutes to switch between cutting different parts because of changing dies. Laser CNC machines can change the program in a short time. This saves time and allows to run smaller production to reduce costs.
Why choose the laser cutting machine?
(1)Good cutting quality
Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can obtain better cutting quality. Especially for small and exquisite cut products, the wood laser cutter near me is always the first choice. It is the best laser cutter for small business.
(2)High cutting efficiency
Because of the transmission characteristics of the laser, the entire cutting process can be fully controlled. During operation, you only need to change the numerical control program to apply the cutting of parts of different shapes. The laser engraving machine for sale can realize consistent two-dimensional cutting or three-dimensional cutting and engraving automatically in a long term. Without manual operations, the laser engraving cutting machine increases cutting efficiency greatly.
High precision is one of the greatest benefits that the best laser cutter and the best laser engraver bring. Laser cutting allows for highly accurate cuts that leave a clean cut and a smooth finish. This has helped products, components, and devices to become much smaller, and greatly reduces material wastage.
There is no contact between the laser head and the workpiece during laser cutting. And the heat-affected area is small. This minimizes the damage to the material surface. It also avoids the costly repair and maintenance schedules for moving parts that contact the materials. To process parts of different shapes, we just need to change the part design and the laser output parameters. The laser cutting process has the features of low noise, low vibration, and no pollution.
(5)Work with many materials
The laser cutting machine can cut various materials down in size or help to create complex and intricate shapes. For metals and alloys, we have metal laser cutting equipment, steel laser cutter, tube cutting laser machines, etc. As for non-metals and composite materials, we have the wood laser cutter near me, laser fabric cutter, leather laser cutter, laser paper cutter, and laser engraving machine for wood.
How much does a laser cutting machine cost?
As we all know, the laser cutting machine price will be more expensive than traditional CNC cutting near me. The cost of a laser cutting machine is mainly composed of the following parts:
- Parts and accessories
- Laser cutting system and laser cutting software
- Freight fees and tax
- Customs clearance fees
- Service and technical support fees
Generally, the cost of a fiber laser machine ranges from $2,500.00 to $300,000.00. The cost of a CO2 laser cutting machine ranges from $1,500.00 to $8,000.00.
4 Factors affecting the laser cutting machine price
Generally speaking, the price of a metal laser cutter is far more expensive than a CO2 one. The factors affecting the price of laser cutters for sale are mainly as follows:
We all know that brand is an added value of any product. The same goes for the laser cutting machine. The brand effect is reflected in the machine quality, kits/parts, performance, and after-sales service. Generally speaking, the cutting and engraving laser machines of big brands will have higher prices than those of small factories.
With the same other configurations, the price of large-sized laser cutting machines is higher than that of small-sized ones. The price of the customized best laser engraver for wood is higher than that of the regular-sized ones.
For example, the home laser cutter machine usually has a working size of less than 600*600mm. You may only pay several hundreds of dollars to buy such a laser cutter engraver. However, some metal laser tube cutting machines are in large sizes to process large-sized metal sheets. For instance, 3000*1500mm and 2000*4000mm. Such a laser CNC machine could cost you over $20,000.
In addition, if you want a custom-size CO2 laser engraver, you may have to pay a bit more than that in a similar regular size.
3.Laser generator brand and power
As we all know, the laser is the core optical component of the laser cutting machine. As for different laser generators, the laser beam quality is also distinctive. At present, imported lasers are superior to domestic lasers in terms of stability and beam quality. The price of imported brand lasers is also higher than that of domestic lasers.
For the same brand laser generator, the greater the laser power, the higher the laser cutting machine price. The CO2 laser wood cutting machine or laser engraving machine for wood usually adopts small power, like 130W and 150W. While the metal engraving and metal sheet or tube cutting machine adopt large laser power, like over 500W. So the price of the laser engraving machine for metal is far more expensive than a CO2 laser engraver for wood.
4.Other key laser CNC machine components
Other key components mainly include guide rails, rack, and pinion, motor, water chiller, etc. Their brand and quality are also the reasons for the price difference. Imported or famous brand parts and components will cost you much.
In conclusion, many factors affecting the price of fiber laser machines and CO2 laser machines. This includes brand awareness, core configuration, optional functions, processing requirements, manufacturers’ service, etc.

How to use the laser cutting machine?
Firstly, we need to check whether all the connecting parts of the laser cutting machine are inserted correctly. Secondly, we should check whether all parts of the laser cutting machine can move freely. Then check whether there are processing materials under the processing table. Next, make sure that the work area and optical components are clean. In addition, check the exhaust system and start the cooling system if necessary. Finally, turn on the main power of the laser cutting machine and the CNC laser cutter starts to run.
1. Put the raw materials on the laser cutting machine table steadily
2. According to the material and thickness of the material, adjust the system cutting parameters of the laser cutting machine.
3. Choose suitable nozzles and lenses, and check whether their appearance and cleanliness are intact.
4. Debug the CNC laser cutter repeatedly to adjust the focus of the cutting head to a suitable position.
5. According to your processing needs, select the appropriate laser cutting gas and check the jet.
6. Draw and typeset the graphics to be cut, and Import them into the cutting system.
7. During the operation, staff are required to observe the cutting condition of the laser cutting machine on site. In case of emergency, the brake button must be pressed quickly.
8. When the laser engraving machine for sale is stopped, clean the guide rails, wipe the equipment rack, and often apply lubricating oil on the guide rails to ensure that there is no debris.
How to maintain a laser cutting machine?
The laser cutting machine price is not very cheap, so as far as possible to extend the service life of the laser cutting machine to better save production costs and win greater benefits. It can be seen that the daily maintenance of the laser cutting machine is very important. The following is mainly explained from six aspects:
1.Water tank cleaning:
Before the machine works, make sure that the laser tube is filled with circulating water. The circulating water quality and temperature directly affect the service life of the laser tube. Therefore, we should regularly replace the circulating water and clean the water tank. This is best done once a week.
Long-term use will accumulate a lot of dust in the fan, and make the fan a lot of noise. Besides, it is not conducive to exhaust and deodorization. When the fan suction is insufficient and the smoke is not smoothly exhausted, the fan must be cleaned.
The reflector and focusing lens are easily stained with dust or other contaminants, which can cause the loss of laser or damage to the lens. So clean the lenses every day. Firstly, the lens should be gently wiped, and the surface coating should not be damaged. Secondly, the wiping process should be handled gently. Thirdly, when installing the focusing lens, be sure to keep the concave surface down.
4.Guide rail cleaning:
During the operation of the laser cutting machine, a large amount of corrosive dust and smoke will be generated. This smoke and dust will be deposited on the surface of the guide rail for a long time, which will have a great bad impact on the processing accuracy of the equipment. And it will also form corrosion points on the surface of the guide rail, shortening the service life of the laser cutting machine. Therefore, the laser CNC cutter guide rails should be cleaned every half a month. Remember that the laser cutting machine should be turned off before cleaning.
5.Fastening of screws and couplings:
After the motion system has been working for a long time, the screws and couplings at the kinematic connection will loosen, which will affect the stability of mechanical motion. Therefore, during the operation of the laser cutting machine, it is necessary to observe whether there are abnormal noises or abnormal phenomena in the transmission parts. At the same time, the laser cutting machine should use tools to tighten the screws one by one after a while. The first firming should be about one month after the equipment is used.
6. Lightpath inspection:
The light path system of the laser cutting machine is completed by the reflection of the mirror and the focus of the focusing mirror. The mirror is fixed by the mechanical part, and the possibility of deviation is high. Although there is no deviation under normal circumstances, it is recommended that the user check whether the optical path is normal before each work.
Precautions that we should pay attention to
The matters needing attention in operating the laser cutting machine are as follows:
1. Bear in mind the safe operation regulations of the cutting machine. Strictly follow the laser start procedure to start the laser, adjust the light, and test the machine.
2. The operator must be trained to be familiar with cutting software, equipment structure, performance, and the operating system.
3. Wear labor protection equipment according to the regulations, and must wear protective glasses when nearing the laser beam.
4. Do not process material before it is clear whether it can be irradiated or cut by laser to avoid the potential hazards of smoke and steam.
5. When the equipment is started, the operator shall not leave the pot or transfer it to someone who is not familiar with the laser cutter for sale. If you must leave, you should stop the machine or cut off the power switch.
6. When an abnormality is found during the processing, the laser cutter engraver should be shut down immediately. And then the fault should be eliminated or reported to the supervisor in time.
7. Keep the fire extinguisher within easy reach. Turn off the laser or shutter when not processing. Do not place paper, cloth, or other flammable materials near the unprotected laser beam.
