What factors determine the price of FPC UV laser cutting machine?
FPC laser cutting machine for small and large enterprises have an indispensable importance.
Large enterprises with a large amount of one-time investment, often more than 10 units, although there is no shortage of money, but consider the cost of the problem, the price of a cutting machine also appears to be important for small and medium-sized enterprises to consider the problem will be more.
So what are the factors that determine the price of the FPC ultraviolet laser cutting machine?
The structure of the FPC laser cutting machine is an integrated device of optical, mechanical and electrical components, the price of the device determines the price of the hardware cost of the FPC laser cutting machine.
1.Laser
Laser is the core device of the FPC laser cutting machine, because the ultraviolet laser belongs to the cold light source, heat-affected area is small, and the spot is small, the cutting edge of the carbonization phenomenon is light, cut the processing speed, can be used for 24 hours of mass production, the mainstream laser on the market at present are used in the ultraviolet laser cutting.
Another part of the manufacturers use domestic ultraviolet laser, relatively speaking, the price difference is very large.
When the shortcomings of domestic lasers is the stability of the power decay faster, so in the case of high-volume processing needs generally use imported lasers.
2. Laser scanner( Galvanometer)
Vibrating mirror can also be collectively referred to as marking head or cutting head, currently imported and domestic price difference is very obvious, almost 10 times the price.
3. Lens
Lens is also known as the field mirror, according to different customer needs, the configuration of different processing width of the lens, generally speaking, the configuration of the lens size of 60 * 60mm or 40 * 40mm lens, and the difference between the traditional marking machine lens is that the FPC ultraviolet laser cutting machine lens for telecentric lens, focusing spot is smaller, the thermal impact of the smaller, and in the cost of telecentric lens are from imported products, and the cost of domestic lenses Compared with the cost of domestic lenses, the price difference is also very large.
4.CCD positioning camera, linear motor
The same positioning camera, linear motor is an important indicator of cutting accuracy, here almost most of the FPC laser cutting machine manufacturers are using imported motors and positioning systems, the price is more or less different, but the difference is not great.
5. Cabinets, marble platforms
Generally speaking, cabinets and marble platforms are customized according to the FPC laser cutting machine manufacturers of their respective standards of production, depending on the width of the processing, but also according to the demand for customized specifications, here there is also a certain price difference, but again, the difference is not large.
6. Control card, industrial computer
FPC laser cutting machine control card are the manufacturers of their own software development, according to customer demand configuration, combined with automation needs design, belongs to the conventional configuration. The industrial control machine is almost the same as the computer, the difference is that it needs to be connected to the device, to be able to control the overall operation, this according to the needs of each company, the price is different, the same is not a decisive factor in the price difference.
From the above you can see that the price determinants of FPC laser cutting machine is closely related to the structure of the FPC UV laser cutting machine, especially the price of the laser and the price of the galvanometer, lens, the price difference is large, so often customers in the purchase of the FPC UV laser cutting machine and then go back to buy to find a big difference in the price, the main reason for the difference is also from this.
The above are the main factors that affect the price of FPC UV laser cutting machines. Of course, there are also other factors, such as the labor costs of various companies. At the same time, we need to be careful not to blindly pursue low-price strategies. In this era, you get what you pay for. When buying equipment, you still have to consider issues such as service life, accuracy, quality, etc. The price is too low. Manufacturers can only make a fuss about spare parts.

What are the precautions for operating a laser marking machine?
1. It is strictly prohibited to start the laser power supply and Q-switching power supply when there is no water or the water circulation is abnormal.
2. The Q power supply is not allowed to operate without load (i.e., the output terminal of the Q power supply should be left floating).
3. In case of any abnormal phenomenon, first turn off the galvanometer switch and the key switch, and then conduct a check.
4. It is not allowed to start other components before the krypton lamp is lit to prevent high voltage from entering and damaging the components.
5. Pay attention to leaving the output terminal (anode) of the laser power supply suspended to prevent sparking and breakdown with other electrical appliances.
6. Keep the internal circulating water clean. Regularly clean the water tank and replace it with clean deionized water or pure water.

What should we do when laser intensity decreases and the marking is not clear enough?
1. Turn off the machine and check if the laser resonant cavity has changed; Fine-tune the resonant cavity lens. Make the output light spot the best;
2. The acousto-optic crystal is offset or the output energy of the acousto-optic power supply is too low;
Adjust the position of the audio-visual crystal or increase the working current of the audio-visual power supply;
3. The laser entering the galvanometer deviates from the center: Adjust the laser;
4. If the current is adjusted to around 20A but the light sensitivity is still insufficient: the krypton lamp is aging. Replace it with a new one.

How to maintain a UV laser cutting machine?
1. It is required to carry out regular cleaning every day, remove debris from the countertop, limiters and guide rails, and spray lubricating oil on the guide rails
2. The waste materials in the collection box should be cleared regularly to prevent excessive waste from blocking the exhaust port.
3. Clean the chiller once every 15 days, drain all the internal water, and then fill it with fresh pure water.
4. The reflector and focusing lens should be wiped with a special cleaning solution every 6 to 8 hours.
When wiping, use a cotton swab or cotton swab dipped in the cleaning solution to wipe from the center to the edge of the focusing lens in a counterclockwise direction.
At the same time, be careful not to scratch the lens.
5. The indoor environment can affect the lifespan of the machine, especially in damp and dusty conditions.
A damp environment is prone to causing rust on the reflective lenses and also easily leading to short circuits, discharge and sparking of the velvet laser.

What accidents might be caused by the laser emission when using a laser cutting machine?
(1) A fire was caused by the laser coming into contact with flammable materials.
Everyone knows that the power of laser generators is very high, especially when it comes to high-power laser cutting machines, the temperature of the emitted laser is extremely high. The possibility of a fire being caused when a laser beam comes into contact with flammable objects is very high.
(2) Harmful gases may be produced when the machine is in operation.
For instance, when cutting with oxygen, it undergoes a chemical reaction with the cutting material, generating unknown chemical substances or fine particles and other impurities. After being absorbed by the human body, it may cause allergic reactions or discomfort in the lungs and other respiratory tracts. Protective measures should be taken when conducting work.
(3) Direct laser exposure to the human body can be harmful.
The damage caused by lasers to the human body mainly includes damage to the eyes and skin. Among the harms caused by lasers, the damage to the eyes is the most severe. Moreover, damage to the eyes is permanent. So when doing homework, you must pay attention to protecting your eyes.

Precautions for laser cutting machines to process various metal materials?
Copper and brass:
Both materials have high reflectivity and excellent thermal conductivity.
Brass with a thickness of less than 1mm can be processed by nitrogen laser cutting.
Copper with a thickness of less than 2mm can be cut. The gas used for laser cutting processing must be oxygen.
Copper and brass can only be cut when a "reflective absorption" device is installed on the system. Otherwise, reflection will damage the optical components.
Synthetic materials:
Processable synthetic materials include: thermoplastics, thermosetting materials and artificial rubber.
Aluminum:
Despite its high reflectivity and thermal conductivity, aluminum materials with a thickness of less than 6mm can be cut, depending on the type of alloy and the capacity of the laser.
When cutting with oxygen, the cutting surface is rough and hard.
When nitrogen is used, the cutting surface is smooth.
Pure aluminum is extremely difficult to cut due to its high purity.
Only when a "reflection and absorption" device is installed on the fiber laser cutting machine system can aluminum materials be cut.
Otherwise, reflection will damage the optical components

What should be paid attention to when laser cutting stainless steel?
Laser cutting processing of stainless steel requires the use of oxygen, under the condition that edge oxidation is not a concern.
If nitrogen is used to achieve an edge free of oxidation and burrs, no further processing is required.
Coating an oil film on the surface of the sheet will achieve a better perforation effect without reducing the processing quality.
