As the laser, reflector and focusing mirror of the laser engraving machine are the core components of its mechanical equipment, each part is indispensable and interacts and cooperates within the laser engraving machine. Therefore, regular inspection and maintenance must be arranged to ensure that they are in good working condition. Although there are many variables that affect the service life of the laser engraving machine, in general, most lasers provide relatively trouble free service in the first five years of operation. If most engraving machines can be maintained regularly and operate normally, there is no problem in using them for 7-8 years. First of all, we need to understand the service life of the main parts of engraving machine and how to maintain the machine to extend its service life, so as to maximize the engraving efficiency.
The laser tube is the consumable of the laser engraving machine, so the service life has become the most important purchase index for users. How long can the laser tube work continuously? Many users use the machine for 8 to 10 hours a day. In fact, the damage to laser tubes and other key components is very large. The laser tube that should have been used for more than one year was scrapped after half a year. The general life of the laser tube is 5000-10000 hours. When the current ratio is relatively small, the laser tube can emit light continuously for 4 hours without major problems, and it will not cause too much damage to the laser tube itself. However, when the laser tube works continuously for more than 4 hours, the temperature in the laser tube will gradually increase. When the temperature rise rate exceeds the heat dissipation rate of the laser tube, the load of the laser tube will increase, and the laser tube will work continuously under high temperature conditions, and its life will decline rapidly. Although the water chiller of the laser tube can take away the internal temperature and dissipate heat to the laser tube in time, the heat dissipation effect is often not enough for continuous use for a long time. This is the case with many appliances. After a long time, it will be too late for heat dissipation and continuous heating. There is something wrong with the laser tube and the high temperature is intolerable. Therefore, it is recommended to turn off the power supply for a period of time after four hours of continuous operation, about half an hour. In addition, when the laser tube works continuously for more than 4 hours, the burden of the laser power supply will increase and the control board will be damaged to some extent.
As time goes on, the laser tube will deteriorate and the output power will decrease. For example, the original output power may drop to the normal power after 5 years, and it may be lower if the mirror and lens are also degraded. As the power drops, the speed setting will have to be lowered to compensate for the reduced wattage. This will cause you to spend more time carving a work that can be completed in a short time. When your laser has been aged for more than 5 years, especially about 7 or 8 years, it is not uncommon for the failure to occur due to the failure of main components. These three fairly common components will frequently fail, including the laser tube, power supply and motherboard.
We have summarized the idea of most experienced laser owners that it is better to replace the aging laser purposefully when it is still running, rather than wait until it is completely dead. If you have a busy shop and you only have one laser, this is particularly true. Adding a second laser allows you to have two fully operable lasers instead of one. This provides a built-in backup plan if any of the lasers fail. You are still operating your small business, even if you are not running at full capacity.
There is no specific time for the lens life, which may be one year or two years, or one minute. Pay attention to the protection to avoid damage. Wipe the lens frequently, do not get dirty, and handle it carefully. During the replacement of the lens of the laser engraving machine and the placement, detection and installation of the lens, attention should be paid to the lens not to be damaged or polluted. After installing a new lens, it needs to be cleaned regularly. This process is quite simple. Correct operation will effectively prolong the service life of the lens and reduce the cost. On the contrary, it will shorten the service life. When the laser machine is working, the optical components in the laser tube will inevitably contact the suspension. When laser engraving, cutting, welding and heat treating materials, the working surface will release a lot of gas and splash, which will damage the lens. When pollutants fall on the surface of the lens, it will absorb the energy of the laser beam, thus producing a thermal lens effect. If the lens does not generate thermal stress, the operator can remove it and clean it. Of course, some methods should be used to avoid damage to the lens and further pollution.
The ambient humidity for machine operation has certain requirements, generally 5 ℃ - 40 ℃ is preferred. If some special environments must be operated below freezing point, the following points should be paid attention to: Prevent the circulation in the laser tube from icing. Once the machine is stopped, the water must be drained. In case of cold or wet weather, it is necessary to start the machine for a few minutes to preheat, remove the moisture and then apply high pressure. When starting, the laser current must be preheated for more than 5 minutes before operation. In addition, in a humid environment, the laser power supply needs a longer preheating time, and only after the moisture is exhausted can the high voltage be applied to prevent damage to the high voltage circuit.
To prevent impurities from entering the machine, clean and oil the core part guide rail in the laser engraving machine guide rail regularly to maintain its flexibility, so as to maintain the processing accuracy at the original value. The guide rail is also the core component of high precision. After each work is completed, it must be cleaned and kept clean and lubricated. The bearing should also be regularly oiled to make the drive flexible, the processing accurate, and extend the service life of the laser engraving machine. Cleaning and maintenance are necessary for normal operation.
The purpose of this is to ensure the normal operation of the laser power supply, to protect the laser tube to a greater extent, and to prevent the circuit from being burned due to poor high-voltage discharge. Ensure the normal operation of the laser power supply, extend the service life of the laser tube, prevent the machine tool from bouncing due to external interference, and prevent accidental circuit damage caused by high-voltage discharge. We must have a good foundation. Keep away from equipment with high power and strong vibration. Strong power interference can sometimes lead to machine failure. Although this is rare, it should be avoided as much as possible. Therefore, large electric welding machines, giant electric mixers, large power transmission and transformation equipment should be kept away from. It goes without saying that the vibration caused by strong vibration equipment, such as forging presses and motor vehicles traveling close to each other, and the obvious shaking of the ground are very harmful to precision carving.
If the heat generated by the laser tube during operation is not controlled, it will cause tube explosion and power supply damage. This is necessary to keep the cooling water smooth, which is also a part of the regular check. Whether tap water or circulating pump is used for stable cooling water, the water must keep flowing. The cooling water takes away the heat generated by the laser tube. The higher the water temperature, the lower the optical output power (15-20 ° C is the best). When the water is cut off, the tube end will break or even damage the laser power supply due to the heat accumulation in the laser cavity. Therefore, check whether the cooling water is unblocked at any time. When the water pipe has a hard bend (dead bend) or falls off, and the water pump fails, it must be repaired in time to avoid power failure or even damage to the equipment.
Generally, buildings are equipped with lightning protection devices. In addition, if the grounding work does well done, there is basically no big problem. As long as the building lightning protection measures are reliable. The item "good grounding" is also helpful for lightning protection. Prompt: In areas with unstable power grid (such as voltage fluctuation exceeding 5%), please install a regulated power supply with a capacity of at least 3000W or above to prevent sudden voltage fluctuation from burning the circuit or computer.
Do not use the computer for special purposes except for installing necessary graphic design software. The computer is equipped with a network card and an anti-virus firewall, which will seriously affect the speed of the laser machine. Do not install an antivirus firewall on the controller. If you need a network card for data communication, please disable the network card before starting the laser engraving machine.
Large amount of dust will be produced by processing materials during the guide rail movement. Maintenance method: wipe the original lubricating oil and dust on the guide rail with a cotton cloth, and then apply a layer of lubricating oil on the surface and side of the guide rail. Maintenance period: 7 days.
After the fan works for a period of time, a large amount of dust will accumulate in the fan and exhaust pipe, affecting the exhaust efficiency of the fan, resulting in a large amount of smoke and dust can not be discharged. Maintenance method: Loosen the hose clamp connecting the exhaust pipe and fan, remove the exhaust pipe, and clean the dust in the exhaust pipe and fan. Maintenance period: 30 days.
After the movement system works for a period of time, the screws at the movement joints will be loosened, which will affect the stability of mechanical movement. Maintenance method: Use the provided tools to tighten the screws one by one. Maintenance period: 30 days.
After the machine works for a period of time, due to the influence of the working environment, the lens will be covered with a layer of ash, which will reduce the reflectivity and transmissivity of the lens, and ultimately affect the working power of the laser. Maintenance method: gently wipe the lens surface clockwise with absorbent cotton dipped in ethanol to remove dust.
]]>A crystal is made up of materials that have been arranged in a particular order by atoms, molecules, or ions. The lattice that develops is three-dimensional. Crystals have distinct structures because of the repeating components. Flat sections or faces, as well as well-defined angles, can be seen in large crystals. Euhedral crystals have well-defined flat faces, whereas anhedral crystals lack distinct faces. Quasicrystals are crystals made up of organized arrays of atoms that aren't always periodic. The term "crystal" is derived from the Ancient Greek word krustallos, which means "rock crystal" as well as "ice."
Crystal gift laser engraving and engraving machine adopts high-performance laser and numerical control technology, mainly composed of optical system, control system and computer software. The energy density of the crystal gift laser engraving and engraving machine must be greater than a certain critical value, or threshold value, which can damage the glass. The high concentration of the laser beam in space and time can reduce the spot diameter to the micron level to obtain a high power density. The smaller the spot, the greater the energy density. Through proper focusing, the energy density of the laser can be made. The laser generates pulses in a very short time. Its energy can instantly heat and break the crystal gift, thereby generating extremely small white spots. Not only can the predetermined shape be carved in the glass, but also the rest of the crystal gift remains intact. Crystal is a crystalline form of silica, while glass is just a molten mixture containing silica. The unit price of crystal is several times or even dozens of times higher than that of glass.
Crystals may be created in a variety of methods. When pressurized molten carbon cools fast, certain crystalline crystals form. Diamonds are produced in this manner. When a solution's liquid evaporates, other crystals develop. This is how amethyst, a purple quartz crystal, is made. Amethyst is made up of a highly concentrated silicon dioxide (SiO2) solution with traces of iron. This solution becomes trapped within a lava bubble. The silicon and oxygen ions gently organize themselves to form a crystal when the water evaporates. The purple color of amethyst is due to the presence of iron. Crystals, on the other hand, cannot form in the center of a liquid. Therefore, they require a beginning place to develop. Once a nucleus is formed, the crystal can begin to expand. A seed crystal is another name for a nucleus, and nucleation is the name for this process. Amethyst crystals grow on the interior of lava bubbles in the case of amethyst. As the lava bubbles cool, stones with crystals on the interior develop. A geode is a name given to such a structure like this.
The term "laser cut" refers to stones that have been cut in a unique form by skilled gem cutters. In truth, there was no laser-cutting machine that could cut stones completely until more recently. Lasers are used in gem-cutting factories to give raw diamonds a preforming rough shape, making the gem cutter's job easier. However, most natural stones are still carved by hand to some extent or another. This will not continue long, as technological advancements will allow gem-cutting techniques to be automated in a short period, and that is where the Monport laser machine comes into play.
Cutting a crystal is relatively straightforward; you start by pressing commands into a computer to specify the regions you need cut and reshaped. Then, the computer will accurately follow the instructions that you give it.
Once you are done typing in the required dimensions, the laser machine will do the rest. The laser beam will cut the lattice at the exact position you commanded the computer to cut. This makes for a more stress-free and contactless process before handing it over to a gem cutter.
Maybe you are interested in selling trophies to sports teams, or selling high-end awards to the corporate market, or maybe selling Engravable gifts to the public. Regardless of your business direction, have you considered selling crystal products? One of the great advantages of the similarity between crystal goods and glass goods is that it can be skillfully integrated into any other similar glass materials used to make prizes and gifts: glass, crystal and optical crystal. Or all these market channels may even become one of your best-selling product lines. According to most people, crystal products are still popular in the field of awards and gifts in the industry. The flash, gloss and smoothness of these products make them high-end attractive and attractive to customers with large budgets (such as those in the enterprise market). Industry suppliers provide a variety of glass and crystal products, from trophies and plaques to vases, photo frames and office desk accessories. Innovation makes crystal carving produce qualitative changes. You can do a lot of things with crystal and glass. Crystal awards and gifts have incomparable attraction to other products. Compared with low-end glass, crystal is more elegant and shiny than glass, especially after personalization. Crystal will certainly attract many markets. If you want to increase your products and income, you should consider adding it to your business.
If you are going to sell crystal gifts and prizes, you need a way to personalize these products. The three methods currently used in this industry are sand carving, laser engraving and mechanical carving. As more and more shop owners buy laser engraving equipment, more and more people begin to study etching glass. CO2 laser is an excellent choice for engraving glass. Laser engraving is highly praised for its simplicity. Laser engraving machine is widely used in two-dimensional crystal photo engraving, personalized crystal inner carving gift customization, high-precision reading crystal products batch processing.
Because this is a non-contact process, the only thing that contacts the crystal is a beam of light, so you don't have to worry about clamping or water cooling the crystal as you do when rotating engraving or preparing photoresist masks or stencils. Since there is no need for fixing except for cylindrical objects, laser engraving provides faster setup and faster processing time than the other two methods. Moreover, everyone in the industry knows that time is money. If mass output is important to you, laser engraving is definitely an option.
Laser etching can be used to mark various glass and crystal gifts and prizes. For example, if you plan to laser engrave cylindrical objects, such as crystal balls, Monport will provide a rotation axis to help you solve this problem easily. Laser engraved glass looks very different from glass marked by other personalized methods. You can get high-quality carving results, but it does look different. You can't get any significant depth. In most cases, the CO2 laser works by evaporating the surface of the material being engraved. However, in the case of glass, the laser will smash or break the surface under the microscope, which may leave very tiny flakes or fragments, and may cause uneven appearance of the filled area. When this happens, sometimes very fine sandpaper can be used to grind it to make it smoother.

CO2 laser was invented in Bell Lab in 1964, also known as glass laser tube, which is a laser product with high continuous output power. It is widely used in textile, medical treatment, material processing, industrial manufacturing and other fields, especially in packaging spray code, non-metal material engraving, medical beauty and other industries with unique applications.
CO2 laser technology was basically mature until the 1980s and was widely used in industrial processing in the next 20 years, including metal engraving, various materials carving, as well as welding, melting processing in automotive, shipbuilding and aerospace. Nowadays, any plucky individual or group of ambitious people can buy a CO2 laser machine and start their own artisan engraving business.
Laser, in English is the abbreviation of Light Amplification by Stimulated Emission of Radiation, laser is generated by atomic excitation radiation, so it is a single frequency, polarized light source, which has been widely used in many fields of people's social life.
During the engraving process, gas is emitted. For lasers to work, the material must absorb the emitted heat. With metals, a large portion of the light is reflected back. Therefore, a powerful laser is needed to generate the necessary heat for engraving despite reflection. The light that bounces back can harm the machine. Some types of metal, like copper alloys and certain aluminium grades are too reflective for CO2 lasers. This is a limitation that hampers different use-cases.
Laser engraving is nothing more than a tool. Unlike other tools, he uses a laser focusing on the small area, somewhat similar to a magnifying glass placed in the sun that sets things in his focus on fire. Compared to other uses of laser power, the laser engraving machine is not very powerful, due to ease of operation and safety considerations, laser engravers are designed to be manufactured into an integrated fully enclosed equipment.
The laser beam in the glass tube is sealed and filled with C02. A high current is sent through the tube, which creates a reaction with the CO2, increasing the energy of the gas particles so that they produce light. When the light reaches this level of brightness, the byproduct is intense heat, which is strong enough to melt materials with enormously high melting points.
There are three reflecting mirrors throughout the optical structure. The first one is beside the laser tube, the second one is above the Y-Axis gantry, and the last one is above the laser head. Light is reflected through the three mirrors backward and forwards across the length of the tube. The mirrors are to intensify the light so that it can gasify most materials.
The role of the focus lens is to refine the laser’s pathway so it’s focused on an exact spot. This extra focusing process is what makes a CO2 laser machines able to produce such precise and clean finishes on a broad range of materials.
The machine also houses a computer numerical control system that allows it to position the laser head in all directions over the work bed. This works alongside the mirrors and focus lens so the beam can create different shapes without losing accuracy or power. The laser can switch on and off at an incredible speed, allowing the operators to engrave beautiful, intricate designs.
There are three main functions you can perform using a carbon dioxide laser engraving machine: engraving, engraving and marking.
In simplest terms, laser marking is a permanent process that uses a beam of concentrated light to create a lasting mark on a surface. Laser marking can be automated and processed at high speeds, while leaving permanent traceability marks on a range of materials, including steel, titanium, aluminum, copper, ceramic, plastic, glass, wood, paper, and cardboard.
Laser engraving is a process that vaporizes materials into fumes to engrave permanent, deep marks. The laser beam acts as a chisel, incising marks by removing layers from the surface of the material. The laser hits localized areas with massive levels of energy to generate the high heat required for vaporization.
Laser cutting is completely remove and separate the material from the top surface to the bottom surface along a designated path. Laser cuts tend to be extremely clean and precise, although it does depend on the material you’re using. For instance, wooden edges tend to have a darker finish than the original color of the wood. One of the best materials for laser cutting is acrylic, which has a lovely glossy and smooth finish, with no discoloration.
Our Monport 60W and 80 W can reach up to 500mm/s, which brings you high efficiency. We Monport set a variety of processing methods in one: bitmap marking cutting hollowing completed once, humanized design makes it more fast and convenient.
The special control software can be compatible with Auto CAD, Corel DRAW, Inks cape and other software output, can realize the automatic arrangement and modification of text symbol, graphic image, bar code, QR code, serial number automatic increase, supports PLT, PCX, DXF, BMP, JPG and other file formats, and can directly use TTF word library.
The beam never actually touches the surface of the material you’re working with. Rather, it causes the material to melt because of the high heat emitted by the laser. This means the materials are less prone to damage — but it also means that the main appendage on the laser machine doesn’t wear down over time.
It is a safe way of marking, engraving or engraving because it doesn’t use a blade or any other sharp implement. Our Monport laser machines adopt fully closed optical path and multiple protection control design, to ensure the overall stability of equipment.The laser beam is tightly sealed in glass, so as long as you carefully follow the safety instructions, there’s practically no risk of injury.
The results you can produce with your Monport are extremely precise and accurate. Extreme heat and intensity from the light of the laser beam melt away the material in the design you enter into the computer. The finish is smoother and cleaner than you’d be able to produce by hand.
Some materials must not go anywhere near a CO2 laser cutter machine. Some of these include halogens, phenolic resins, epoxy, beryllium oxide, Teflon, PVB, PVC, carbon and any artificial or real leather containing chromium. Here’s a table of materials that are generally effective and safe for use with a laser engraving machine.
