What Is Laser Marking Machine?
A laser marking machine, also called laser engraving machine, laser printing machines, laser etching machine, laser markers, laser mark machines, laser marking systems, laser stippling machines, laser labeling machines and laser marking tools, is an advanced device designed to create permanent marks on a wide range of materials with exceptional precision and durability. The equipment utilizes a focused laser beam that operates through an opto-mechanical integration system that combines optical, electronic and mechanical components and an automatic control system. The marking process involves evaporating the surface material to expose the substrate, resulting in fine patterns, logos and text. There are several types of laser marking machines including CO2, fiber, semiconductor and YAG types, each of which can process different materials. These machines excel in industries with demanding processing requirements such as electronics, automotive manufacturing, jewelry, medical devices and construction materials. The precision machining process makes them a must-have tool for complex and high-quality engraving needs.
How Does A Laser Marking System Work? – Working Principle
A laser marking system consists of a power supply system, a laser source, a cooling system, an optical scanning system, a Q-switch and a focusing system. The AC power supply powers the computer, the Q-switch power supply, the cooling circulating pump, the laser power supply, and the laser light source, respectively. Here is how a laser marking machine works:
- Emission of laser light: The laser source is powered by the power supply, and then the laser beam is generated by the resonant cavity formed by the reflector and the YAG condenser.
- Pulse Modulation: The Q-switch modulates the beam into high power pulses of a specific frequency, suitable for precise marking.
- Optical Scanning and Focusing: The pulsed laser passes through an optical scanning system that controls the path and speed of the laser. A focusing device ensures that the beam is centered on the surface of the workpiece and can be adjusted to keep it in the focal plane.
- Marking Execution: A computer-controlled scanning system guides the laser to mark text or patterns and automatically corrects for image distortion to ensure processing accuracy.
- Cooling System: Deionized water in the cooling unit regulates the temperature of critical components, such as the Q-switch and condenser, to prevent overheating and enhance the machine’s ability to keep working.
- Positioning aid: An auxiliary laser beam indicates the marking position for calibration and adjustment prior to processing.
With the cnc system, the machine’s components are precisely coordinated to achieve high-quality, repeatable laser marking on a wide range of materials.

How to Maintain Laser Marker?
Laser marking machine is a high-tech product that integrates laser technology, optical technology, precision machinery, electronic technology, computer software technology, and refrigeration. If laser marker always maintains stable performance and longer service life, it needs to be effectively maintained and maintained to ensure the normal function of the machine and improve the work effect. TPLASER introduces you how to maintain and maintain the laser marking machine
- Control system: mainly composed of scanning galvanometer, computer, control software (board card), etc. If the computer crashes or the software does not respond, you should turn off the galvanometer switch immediately; delete some junk files and unnecessary software regularly; organize the hard disk regularly to ensure that the hard disk data is organized and speed up the software operation; don’t be unclear about the future The files and software added to the system, so as not to be affected by the virus, to ensure that the system works in a non-toxic environment.
- Cooling system: mainly divided into air-cooled and water-cooled, the cleaning methods of the two are different.
①The air-cooled machine, that is, the fan, will accumulate a lot of dust in the fan for a long time, which will cause the fan to produce a lot of noise, and it is also not conducive to exhaust and deodorization. When the wind of the fan is insufficient and the exhaust is not smooth, we need to turn off the power first to remove the dust in the fan.
②Water cooling requires the use of purified water, deionized water or distilled water. Tap water, mineral water and other liquids containing higher metal ions or other minerals should not be used. Pay attention to the replacement of the circulating water, usually once a week. The water tank is cleaned. It is necessary to ensure that the machine dissipates smoothly, and at the same time, no external heat is allowed to blow directly to the machine.
- Optical path system: working by the reflector and focusing mirror. In the laser marking machine, whether the focusing mirror position is normal or not will directly lead to the spread of the optical path. Therefore, the optical path system must be checked at all times to ensure the machine’s performance. working normally.
- Lens system Lens: Generally speaking, the lens system of a laser marking system is composed of several objective lenses. Before cleaning them, laser marking machine should be shut down, and the lenses should be removed in order and wiped gently. Remember: Do not damage the surface coating. The lens is a fragile item. Please handle with care, and install the lens correctly.
- Laser marking system working environment: ①In the hot summer, when we get into the air-conditioned room because we are afraid of the heat; in the cold winter, when we get into the air-conditioned room or burn fire or heat because of the cold, you need to know the laser marking machine is also afraid of heat and cold, so under high temperature or cold weather, it is necessary to do a good job in the maintenance and maintenance of laser marker. The working environment temperature of the machine should be kept at 15-30℃, and the humidity should be 45-75%. UV laser marking machine has a slightly higher requirement for the working environment, the temperature should be kept at 16-28℃, and the humidity should be 45-75%.
②Don’t put it next to the equipment with large vibration of machine tools such as stamping;
③The environment of the processing site must be smoke-free and dust-free, and do not work in a polluted environment.
- The fluctuation of the power supply grid should be less than 10%. If it cannot be guaranteed, a voltage stabilizer must be installed.
- Laser marker is exposed to the air for a long time due to its own characteristics, and it is easy to accumulate dust on the circuit board after a long time, and it is easy to cause a short circuit if it is not cleaned for a long time. The cleaning method is to turn off the power of the controller, open the outer cover of the box, and blow out the dust inside. Pay more attention to the dustproof work on the outside of the chassis.
- Don’t turn on and off frequently, at least 3 minutes after turning off the machine before turning on the machine.
- When not in use for a long time, keep the working area dry to prevent the optical lens from being damp and moldy.
