What is a laser engraving machine?

Brief introduction:

A laser engraving machine is the equipment that uses the thermal energy of laser to engrave the suitable materials. It mainly contain three parts, i.e. the laser, the controller and the working table.

The laser engraving machine is different from the mechanical engraving machine and other traditional manual engraving methods. The laser engraving machine adopts computer numerical control technology as the basis and takes laser as the media of processing. And it uses laser beams to make permanent marks on the surface of various materials. The materials melt and vaporize physically under the laser engraving irradiation, resulting in engraving marks. As it is non-contact processing, the laser engraving machine will not cause mechanical deformation or damage on the work-piece.

How does a laser engraving machine work?

The tool of the laser engraving machine lies in the laser and laser beam. The laser will generate a laser beam, and the optical mechanism will transmit such a laser beam and make it focus on the surface of the material. The material is quickly vaporized to form pits, with the action of the high-energy-density laser beam.

  1. The laser engraver uses a computer to control the X, Y, and Z axes to drive the laser head to move, and control the laser to switch as required. The image information processed by the software is designed previously and stored in the computer.
  2. When the laser engraver reads design information from the computer in sequence, the laser head moves back and forth from left to right and up to down along the design route. And finally, it forms a full piece of graphics or text, realizing the automation of carving.
  3. The laser processing technology belongs to non-contact processing. The tool of mechanical engraver carves through direct contact with the material. But laser engraving machine does not change the internal elements of the material. It relies on the high density of laser energy and has strong laser engraving operation performance.

Its features include a wide range of processing materials, and smooth cutting edges without secondary polishing. And it will generates no dust, and achieve fast processing speed, and high precision, less waste, and high efficiency.

Laser engraving machine types

According to the laser sources, the laser engraving machines can be roughly divided into CO2 laser engraving machines and fiber laser engraving machines. But Blue Elephant also supplies the laser machines specially for some materials.

  • CO2 laser engraving machine

Mainly used for the processing of non-metal materials, such as wood, acrylics, paper and leather;

  • Fiber laser engraving machine

Mainly for the marking processing on metal materials, and some resin and plastics;

  • Glass engraving machine

Specially designed for glass marking and engraving;

  • Laser engraving machine for metal

Specially designed for copper, aluminum and stainless steel, etc.;

  • Mini laser engraver

Specially for marking or cutting small-sized work-piece.

Generally speaking, compared with mechanical engraver, the laser engraving machine has a wider range of use. And the engraving accuracy is higher, and the engraving speed is faster.

Moreover, compared with the traditional manual engraving method, the laser for engraving can also achieve very detailed and lifelike engraving processing effects. This is not inferior to the level of hand-carving by experienced craftsmen at all.

How to use a laser engraving machine?

The users need to follow the instructions of the laser engraving machine for safe operation. And it needs to start the laser engraving machine strictly in accordance with the laser start-up procedures. The operators must accept the training for technology and operation and are familiar with the structure and performance of the machine. They need to master relevant knowledge of the operating system.

  1. Before starting the machine, the operators should wear labor protection equipment as required. They must also wear protective glasses that meet the requirements near to the laser beam.
  2. After turning on the machine, the operators manually drive the machine along X and Y axes at low speed. This is to check whether there is any abnormality.
  3. Input the program for a new work-piece; and then, it needs to do a test run first and check the operation status.
  4. After the test run is Ok, the operators can place and fix the work piece on the working table, and start up the operation.
  5. During the process of working, the operators need to pay attention to observe the operation of the machine tool. This is to avoid accidents caused by the engraving machine beyond the effective travel range or collisions.
  6. During the operation, it needs to keep the laser, working table, and the surrounding area clean, orderly, and free of oil pollution. The work-piece, plates, and waste materials need to be stacked as required. Keep the fire extinguisher within easy reach. Do not place paper, cloth or other flammable materials near the unprotected laser beam.
  7. If there is any abnormality appears during processing, the operators must shut down the laser engraving machine down immediately. And then it needs to eliminate the fault or report to the supervisor.

 

Note: Before processing a new material, the operators need to make it clear whether the laser engraver can process it. This is to avoid the potential hazards of smoke and vapor.

After starting up the equipment, the operator shall not leave the position or ask others to supervise the operation without authorization. If it is necessary the operators have to leave for a while, the operator should stop the machine or turn off the power switch.

How to maintain a laser engraving machine?

 

  1. It shall maintain the laser engraving machines regularly, in order to increase the service life, save costs, and create greater benefits.
  2. When the laser engraving machine finishes processing, it needs to turn off the power of the machine and computer. And the operators also need to cover the cap of optical lens. This is to prevent dust polluting the optical lens.
  3. The circuit is in a high voltage state when the laser engraver is at work. It needs to prohibit the unqualified staffs to maintain the laser engraving machine.
  4. If the engraving effect is not good, please carefully check if any contamination on the surface of the focusing lens.
  5. Sometimes, the laser engraver is working continuously for many hours. And the lower surface of the focusing lens will absorb the dust in the air. It will affect the engraving effect. Therefore, it needs to clean the focusing lens after long-time operation.
  6. The users need to clean the cooling fins of the water chiller regularly to avoid excessive dust affecting the work. It also needs to replace the distilled water in the water tank every four months. Tap water or purified water should not be used.
  7. The first-stage filter of blower on the side of the optical lens of the reflector path must be checked at any time. There must be no water or oil, otherwise the lenses will be contaminated. The users must improve the air source to make it reach the standard.
  8. Check the protective gas of the external light path, freezer, cooling water circuit and air compressor once every week. And drain off the filter once a week.
The impact of laser engraving machine accessories on the laser engraving machine price

The accessories of the laser engraving machine directly affect the service life and overall processing performance of the engraving machine. Of course, the engraving machine parts are different, and the price of the engraving machine varies greatly. Normally, the higher the configuration of the engraving machine, the higher the price of the engraving machine. But it is not that the higher the configuration of the machine is suitable for us. We should choose the laser engraving machine according to our own processing needs.

The influence of the brand on the laser engraving machine price

The brand is the added value of a product. Products of well-known brands are often more secure in terms of product quality, assembly, production technology, and after-sales service. Therefore, the laser engraving machine is the same. For example, for the same functional laser engraving machine, the laser engraver price with a greater brand power will be slightly higher.

The performance and the laser engraving machine price.

There are many types of laser engraving machines, and their performance varies greatly. Therefore, processing performance is also one of the main factors affecting the laser engraving machines price. Normally, the processing is relatively complicated, and the laser engraving machine with finer processing requirements is more expensive.

How does the processing material affect the laser engraving machine price

The processing material mainly involves the properties of the material and the processing thickness. Generally, the thicker the processed material, the greater the power requirement of the laser engraving machine. Therefore, the price of the laser engraving machine is higher. In addition, for some special processing materials, auxiliary gas is required to complete the ideal processing of the material. Therefore, the overall price of the laser engraving machine is relatively higher.

How to buy a laser engraving machine?

There are various kinds of laser engraving machines on the market, so how to choose the most suitable one? The following points may help you:

  1. Firstly, the users may investigate the market, and see what machine that others in the same industry are using. They can also judge the processing method or technology through the finished products.
  2. Secondly, please determine what materials to engrave mostly. As mentioned above, the CO2 laser machine is mainly for the processing of non-metal products, and the fiber laser machine focuses on metal materials.
  3. Thirdly, the users may consider the size of the materials for laser processing. It is about the choice of the size of the working table of the laser engraving machine. But the users should notice that the large size of the machine is not necessarily good. Because the large-size equipment is of course more expensive. 

If the work-piece is small, and the working table is large, the laser output some laser machines may become unstable. It will result in irregular depths on the same working table. Therefore, it is better to choose the most appropriate working table in combination with the size of the work-piece.

  1. Power of laser tube: The users can select appropriate laser tube wattage according to the material and the content of the engraving. For example, the engraving of acrylic and double-color boards do not require too large power. But the wood and stone engraving and cutting will require a higher-power laser tube. 
  2. After-sales maintenance service: After-sales maintenance service of the laser engraving machine is very important for the users. Some customers may purchase the laser engraving machine for the first time. And they may encounter operation questions or doubts during the operation process. If the suppliers offer good technical after-sales service, it will be very helpful for the continuity and efficiency of processing.
