Laser engraving is based on computer numerical control technology. First, you need to make a design of laser engraving file, then, open the file through laser software, and start CNC programing, the laser engraver machine will start working after the control system received the control command. The laser beam is reflected through laser mirrors, the laser focal point downward through laser lens, where the heat is most intense. Thus, the laser beam starts impinging on the material, the material will burn or evaporate, and the color will change as well, and make a contrast. After a while, a complete laser engraved project will be finished.

Laser engraving machines are widely used in various industries of Embroidery, Brand processing, Packaging and printing, Advertisement decoration, Architectural Models, Wood processing, Smartphones and Laptops, Laser knife mold, Crafts, Leather clothing, Shoes, Toys, Fablabs/Education, Medical Technology, Rubber Stamps industry, Watches industry, Architectural Models, Packaging Design, Automotive Industry, Mechanical engineering, J Awards and Trophies, Sign/Displays, Signage, Giveaways, Electronics Industry, Data plates, Jewelry industry, Ball bearing, Barcodes serial numbers, etc. With a laser engraving system, you can engrave different designs on different material surfaces. The laser beam will make the surface to vaporize. It is a good idea for someone who wants to customize or personalize something.

If you have an idea to buy a cheap laser engraver, you may wonder how much does it cost? how to get a fair price or final price? The laser engraving machine cost is composed of the following items: 1. spare parts. 2. software and system. 3. tax rates. 4. shipping costs. 5. customs clearance. 6. service and technical support. A fiber laser engraver cost is from $3,000.00 to 28,500.00. A CO2 laser engraver cost is from $2,400.00 to 70,000.00. An UV laser engraver cost is from $10,000.00 to 30,000.00.

Laser engraving is the application of CNC laser technology to make text or pattern on the object. While engraving, the surface of the object is still smooth, and the writing will not wear. The laser beam does not touch the surface of the material, is not affected by mechanical motion, and the surface does not deform, generally no need to be fixed. Laser etching is not affected by the elasticity and flexibility of the material, and is convenient for soft materials. Laser etching has high precision, high speed and wide application fields.

Laser engraving machines are divided into laser wood engraving machines (laser wood engravers), laser metal engraving machines (laser metal engravers), laser leather engraving machines (laser leather engravers), laser stone engraving machines (laser stone engravers), laser fabric engraving machines (laser fabric engravers), laser plastic engraving machines (laser plastic engravers), laser rubber engraving machines (laser rubber engravers), laser paper engraving machines (laser paper engravers), laser glass engraving machines (laser glass engravers), laser acrylic engraving machines (laser acrylic engravers) according to engraving materials. Laser engraving systems are divided into CO2 laser engravers, fiber laser engravers, and UV laser engravers according to laser source. Laser engraving tables are divided into mini laser engravers, handheld laser engravers, compact laser engravers, desktop laser engravers, portable laser engravers, 2x3 laser tables, 2x4 laser tables, 4x4 laser tables, 4x8 laser tables, 5x10 laser tables, large format laser tables according to table sizes. Laser engravers are divided into home laser engravers, hobby laser engravers, industrial laser engraving machines according to applications. Laser engraving machines are divided into laser jewelry engraving machines, laser pen engraving machines, laser iPhone engraving machines, laser gun engraving machines, laser ring engraving machines, laser signage engraving machines, laser art engraving machines, laser logo engraving machines, laser cup engraving machines according to industries. If you are working for cylinder engraving, a rotary laser engraver machine is the best solution.

1. First check whether the laser tube is damaged and whether any parts are loose.
2. Install the exhaust device, connect the exhaust pipe to the exhaust fan, and install the other end outdoors. The maximum distance between the exhaust fan and the outdoor air outlet is 2 meters. If it is caused by the local environment, if the exhaust pipe extends too long, you need to configure additional exhaust equipment.
3. Connect the ground wire (see the grounding position behind the machine, the grounding resistance should be ≤4 ohms).
4. Check the 220V power supply line for aging of the wireless circuit, loose connectors, poor contact, etc. The 220V AC voltage is normal. If necessary, a special power supply line and a regulated power supply (power ≥3000W) must be used.
5. This machine uses an external submersible pump circulating water supply cooling device. The user must prepare a capped bucket. The height difference between the engraving machine and the submersible pump should not be greater than 0.5 meters. The cooling circulating water must be clean, dust-free, and scale-free.
6. The water temperature of the circulating cooling water should be 5-25 ℃, otherwise it will affect the engraving depth. In the cold area, it should be ensured that there is no ice blockage in the tube, otherwise the laser tube will burst. It is best to drain the remaining water in the circulating water channel and tube when it stops working at night to prevent frost cracking.
7. If the laser tube is found to be short of water, it should be shut down immediately to stop working, cut off the power of the pump, and at least shut down for more than half an hour, wait for the laser tube to cool naturally before the water can be started to work.
8. Turn on the submersible pump, the cooling water should circulate normally, and the cooling water channel should be free from clogging and dripping.
Note: Do not connect the zero wire to the ground wire.

1. First turn on the main power switch, turn on the voltage regulator, and turn on the chiller (let the water in the laser tube fill up and cycle for 1-3 minutes). You should put antifreeze in the chiller in winter and snow days.
2. Turn on the power of the machine and reset the machine.
3. Turn on the fan power and air pump.
4. Turn on the laser switch (turn on the machine to emit light), and then turn on the lighting switch.
5. Press the burst button to detect whether the laser is emitted.
6. Turn on the computer (the computer's USB cable is connected to the machine interface), open the control software, click the software up, down, left and right buttons to check whether the machine is moving. The machine movement indicates that the computer is connected to the machine.
7. Put the workpiece and adjust the anxiety (in general, we only measure the distance from the cutting nozzle to the surface of the material), long focal length lenses for cutting thick materials, and short focal lengths for fine engraving machines.
8. Operate the computer to transfer files, position the machine, walk the frame (test whether the area of the cut file is within the effective range of the workpiece), and start engraving.

1. Different Definition.
Laser marking machine uses a laser beam to evaporate the surface material to expose the deep material, which leads to chemical changes in the surface material and physical changes to engrave marks, or to burn part of the material through light energy to show the desired etching pattern and text.
Laser engraving machine is a laser device that uses laser beam to engrave and cut the material that needs to be engraved. It is also called laser cutting machine, laser etching machine and more. Unlike mechanical engraving machine, it uses laser heat energy to engrave materials.
2. Different Application Material.
Laser engravers are generally used for engraving or cutting non-metallic materials. Laser marking machines are generally not used for deep engraving. It only needs to engrave the logo content. It can mark on most metal and non-metal materials.
3. Different Depth & Speed.
Laser engraving system can engrave on a large stroke size, and it can also cut, the engraving depth is far greater than that of the laser marking system; The speed of the laser marker is much faster than the laser engraver, and generally can reach 5000 mm/s - 7000mm/s.
4. Different Laser Generator and Price.
The optical path system of the laser engraver machine is composed of three reflective lenses and a focusing lens. The laser is generally a carbon dioxide glass tube. However, there are many types of laser generators in laser marking machines, including fiber laser generators, CO2 laser generators, UV laser generators, and so on.
The price of laser marking machine is different due to different models and materials, and the price ranges from tens of thousands to hundreds of thousands; Low-power laser engraving systems for cutting non-metallic materials are much cheaper than laser marking systems, but high-power laser is also more expensive.
