How Does A Laser Engraving Machine Work? - Working Principle

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.

What Are The Advantages And Benefits Of Laser Engraving?

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.

1. The precision workbench can be used for fine micromachining;

2. Use a microscope or camera system to observe or monitor the condition of the engraved surface;

3. It can pass through light-transmitting materials (such as quartz, glass) to engrave its internal parts;

4. It can process most metal or non-metal materials;

5. The laser beam is very thin, so that the consumption of the engraved material is small;

6. During laser etching, X-rays will not be generated like electron beam bombardment and other engraving methods, and will not be interfered by electric and magnetic fields;

7. It can mark the surface of "millimeter-level" parts;

8. The laser uses non-mechanical "tools" for engraving, which does not produce mechanical extrusion or mechanical stress on the material, has no "tool" wear marks, is non-toxic, and rarely causes environmental pollution;

9. The prism and mirror system can be used to focus the beam on the inner surface or inclined surface of the workpiece for etching;

10. The operation is simple, the use of numerical control technology can realize automatic engraving, can be used for high-speed and high-efficiency engraving of parts on the production line, and can be used as a part of the flexible machining system.

How To Setup And Install A Laser Engraver? - Beginner's Guide

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 Engraving Machine? - Basic Operation Guide

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.

What Are The Differences Between Laser Engraving Machine And Laser Marking Machine?

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 engraver kit 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.
