What are the parts of a metal laser cutting machine?

1.Fiber laser:

It is the core component of the metal laser cutting machine and the “power” for the metal laser cutting machine to realize the cutting operation. Compared with other types of lasers, fiber lasers have the advantages of higher efficiency, longer service life, less maintenance, and lower cost.

2.Cutting head:

The cutting head of the laser cutting machine is a laser output device, which is composed of a nozzle, a focus lens and a focus tracking system. The cutting head of the laser cutting machine will follow the set cutting track, but the height of the laser cutting head needs to be adjusted and controlled according to different materials, different thicknesses and different cutting methods.

3.Water chiller:

The chiller is the cooling equipment of the laser cutting machine, which can quickly and effectively cool the laser, spindle and other equipment. The current chillers all include input and output control equipment switches, as well as advanced functions of cooling water flow, high and low-temperature alarms, and their performance is more stable.

4.Servo motor:

Servo motor refers to the engine that controls the operation of the mechanical components in the servo system. It is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately and can convert the voltage signal into torque and speed to drive the control object. The high-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the laser cutting machine.

5.Air supply system:

The air supply system of fiber laser cutting machine mainly includes air source, filter device and pipeline. There are two sources of air: bottled air and compressed air.

6.Control system:

Mainly control the machine tool, realize the movement of X, Y, Z axis, and control the output power of the laser.


The bed, beam, worktable and Z-axis system of the laser cutting machine are collectively called the host. When the laser cutting machine performs cutting, first put the workpiece on the worktable, and then use the servo motor to drive the beam to control the movement of the Z axis. Users can adjust the parameters according to their needs.

How to choose a metal laser cutting machine

When choosing a fiber laser cutting machine, you need to consider your own needs, such as the thickness of the material to be cut, or the different materials that need to be cut will also affect the power of the purchased equipment. Generally, manufacturers will combine the needs of customers. To match. When purchasing a fiber laser cutting machine, you also need to pay attention to the selection of power. The higher the power means the cutting speed can be increased, and thicker plates can also be cut, but the power selection also needs to be combined with the operating scene.

Should pay attention to the core components, for the laser cutting machine, what will affect the quality of the laser is the chiller, the cutting head and the laser. Each different brand will have a difference in price. If you want to effectively reflect the stability and guarantee the after-sales service, you should first choose a professional manufacturer that can ensure high-quality quality. It is not easy to always malfunction in the later use, and it will not affect the normal use.

How much is a metal laser cutting machine

The fiber laser cutting machine has also analyzed the processing cost for everyone before. The processing cost per hour for the 850W solid laser cutting machine to cut 1mm stainless steel (using air) is about 50,000 US dollars, and the 500W fiber laser cutting machine cuts 1mm about 110,000 US dollars. The processing cost of stainless steel (using oxygen) is $3.

If there is a lot of business, we calculate it based on the non-stop operation 24 hours a day. The solid-state laser cutting machine costs US$112 per day, and the fiber laser cutting machine costs US$42 per day. The daily output value of the solid laser cutting machine can reach 1900 yuan, the fiber laser cutting machine can reach 52 US dollars, and the labor is 33 US dollars per day.

As the brand of Chinese laser cutting machines becomes stronger, the competition between products and enterprises is no longer a single price competition. Hidden elements such as quality, service, added value, channels, and enterprise development strategies are also the long-term development of enterprises and brands. An important aspect of a sustainable development competition.

Cutting machine cost recovery time: 133333/418≈281 days; the above is an ideal processing estimate, but according to the actual customer’s response and the business processing volume is relatively large, the cost recovery time of the 850W solid-state laser cutting machine is 1 About half to two years. The cost recovery time of 500W fiber laser cutting machine is about 2 to 2 years.

3 steps of laser cutting machine operation

In fact, the principle of increasing the capacitance to make the metal laser cutting machine more stable is that the capacitance between the capacitance sensing ring and the steel plate to be cut forms a capacitance between the two plates, and the size of the capacitance is related to the distance between the two. In order to compensate for the instability of height control when manually adjusting and cutting, the metal laser cutting machine is equipped with an imported follow-up capacitor height controller. No matter how thick the board is to be cut, the height can be kept consistent with the capacitive height-adjusting the cutting head.
The height of the laser cutting head needs to be adjusted and controlled. The distance between the cutting nozzle and the surface of the workpiece determines the cutting quality and cutting speed. In addition to selecting the appropriate cutting nozzle model and air pressure parameters according to the cutting situation, the metal laser cutting machine needs to increase or decrease the height between the cutting head and the steel plate according to the thickness of the cutting material. Different thickness steel plates use different parameters. At the same time, the cutting nozzle should be adjusted to the corresponding height.
Adopt the method of increasing the capacitance. However, we need to check the metal laser cutting machine as a whole before adjusting to see if there are any faults or problems and adjust according to the actual situation after confirming that there are no problems. These are all done by the professionals of the manufacturer, we still don’t make adjustments privately for safety.

Which materials can be cut by the optical fiber cutting machine, and which materials can not be cut?

The metal laser cutting machine will have a good effect when facing different metals, whether it is a non-ferrous metal or a stainless steel metal, even some highly reflective metals can all be cut, but now the thickness of the cut is basically The upper surface has reached about 100 mm, but what kind of board can be cut is also related to the power we choose. Therefore, it is recommended that you also need to pay attention when choosing. In addition, various types of wood are also very good. The effect, but some woods may have an ignition effect during the cutting process. It is recommended that everyone must be vigilant.

Optical fiber cutting machine can also effectively cut glass.

Glass has the characteristics of being easy to break. If we choose laser cutting machine, it is basically impossible to complete it. If we want to improve all the problems, it is best to choose optical fiber. The cutting machine can quickly achieve a good effect, but at the same time, we should also understand that not all materials can be cut, and there are some materials that he cannot cut.

The optical fiber cutting machine has already become common equipment in the current market.

It seems that it can cut many things, but it also has some taboos. We will find that most of the materials it can cut are made of plastic and steel. Or it is a wooden board. The main purpose is to effectively avoid safety hazards. Try not to choose to contact polyvinyl chloride. This is a toxic substance. During the cutting process, it will affect both the operator and the machine itself. Causes a certain amount of damage, so when we choose to run, these aspects should be paid attention to, it is best to choose the correct method to operate.

What is the difference between a fiber laser cutting machine and CO2 laser cutting machine?

At present, in the metal processing market, fiber laser cutting machines have gradually replaced CO2 laser cutting machines and traditional processing methods, becoming the mainstream equipment in sheet metal processing. What is the difference between fiber laser cutting machine and CO2 laser cutting machine, and what are the advantages?

  1. Different luminous media
    In the CO2 laser cutting machine, gas is the medium that generates the laser beam, and the beam is transmitted through the reflector. Fiber lasers are transmitted through diodes and fiber optic cables. Multiple diode pumps generate laser beams, which are then transmitted to the laser cutting head through flexible fiber optic cables instead of transmitting the beams through mirrors.
  2. The appearance of fiber laser cutting machine is more compact
    Due to the different laser transmission structure, the fiber laser cutting machine with the same power in appearance and size is more refined than the CO2 laser cutting machine, thus saving workshop space.
  3. The conversion efficiency of optical fiber laser cutting machine is higher
    With fiber laser complete solid-state digital module and single design, fiber laser cutting machine has higher electro-optical conversion efficiency than carbon dioxide laser cutting. The actual utilization rate of each power supply unit of CO2 laser cutting machine is about 8% to 10%, while for fiber laser cutting machine, this value is about 25% to 30%. The overall energy consumption of fiber laser cutting system is more than that of carbon dioxide cutting. The system is about 3 to 5 times less, which increases the energy efficiency to more than 86%.
  4. The processing effect of fiber laser cutting machine is better
    Fiber laser has the characteristics of short wavelength, which improves the absorption of the cutting material to the beam, and enables cutting such as brass and copper as well as non-conductive materials. When cutting materials up to 6mm thick, the cutting speed of a 1.5kW fiber laser cutting machine is equivalent to that of a 3kW carbon dioxide laser cutting machine.
  5. The maintenance cost of fiber laser cutting machine is lower
    The CO2 laser cutting machine uses gas as the luminous medium. Due to the purity of the CO2 gas, the resonant cavity will be polluted and needs to be cleaned regularly. The reflector needs to be maintained and calibrated, so the daily maintenance workload is greater. For a multi-kilowatt CO2 laser cutting machine, this item requires at least US$20,000 per year. In summary, fiber laser cutting is more environmentally friendly and convenient in the daily maintenance of equipment.

How to maintain the CNC metal laser cutting machine

Many companies are using fiber cleavers, but they don’t pay attention to the correct maintenance. No matter how perfect the equipment is, it’s extremely important to focus on inspection and maintenance, otherwise it may cause more failures, and you also need to pay attention to whether there is any In the case of deformation, if you do not pay attention to strength and correct operation during use, it is easy to deform due to violence, which will affect normal use. If there is no replacement in the first time, it will be invisible. It will increase the cost and also affect the quality of the cutting. There are also many products that may need to pass the second processing, which will affect the efficiency of the work. Therefore, when we use the process in normal times, basically every 1 Major maintenance should be carried out in ~3 months, and regular inspections should also be carried out after the work is over to see if there is a fault. If there is an abnormality, it should be repaired immediately.
