What is a Laser Engraving Machine?

Laser engraving machine is a kind of laser equipment with CNC (Computer Numerical Control) system that adopts Fiber/UV/CO2 laser beam to engrave 2D/3D letters, numbers, texts, patterns, photos, pictures, signs or logos on the surface of Metals (steel, copper, brass, aluminum, gold, silver, alloy, iron), Acrylic, Delrin, Glass, Rubber, Wood, Fabric, Plastic, Leather, Paper, Stone, Textiles.  A laser engraver machine is composed of machine frame, CNC controller, laser generator, laser engraving head, laser power supply, laser tube, laser lens, laser mirror, servo motor or stepper motor, gas storage tank, gas cylinder, water chiller, dust extractor, air cooling filer, dryer, air compressor, laser engraving software and system. Laser engraving machine is also called as laser engraver, laser engraver machine, laser engrave machine, laser etching machine, laser etch machine, laser etcher, laser etcher machine, laser stippling machine, laser engraving system, laser engraving table, laser engraving equipment, laser engraving tool, laser branding machine, laser printing machine.

How Does a Laser Engraving Machine Work?

Laser engraving is based on computer numerical control technology. First, you need to make a desigh of laser engraving file, then, open the file through laser engraving 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 engraving project will be engraved.

What is a Laser Engraver Used For?

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.

How Much Does a Laser Engraver Cost?

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

Technical Parameters

What are the Advantages and Benefits of Laser Engraving?

Laser engraving is the application of 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 engraving is not affected by the elasticity and flexibility of the material, and is convenient for soft materials. Laser engraving has high precision, high speed and wide application fields.

How Many Types of Laser Engraver?

Laser engraving machines are divided into laser wood engraving machines (laser wood engravers), laser metal engraving machines (metal laser engravers), laser leather engraving machines (leather laser engravers), laser stone engraving machines (stone laser engravers), laser fabric engraving machines (fabric laser engravers), laser plastic engraving machines (plastic laser engravers), laser glass engraving machines (glass laser engravers), laser acrylic engraving machines (acrylic laser engravers) according to engraving materials. Laser engraving systems are divided into CO2 laser engraving systems (CO2 laser engravers), fiber laser engraving systems (fiber laser engravers), UV laser engraving systems (UV laser engravers) according to laser source. Laser engraving tables are divided into small/mini laser engravers, handheld laser engravers, tabletop/desktop laser engravers, portable laser engravers, 2x3 laser engraving tables, 2x4 laser engraving tables, 4x4 laser engraving tables, 4x8 laser engraving tables, 5x10 laser engraving tables, large format laser engraving 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.

How to Setup and Install a Laser Engraver?

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.

How to Use a Laser Engraver Machine?

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.
