What Advantages Does Laser Cutting Have Over Other More Conventional Cutting Methods?

Laser cutting offers a huge number of benefits over other more conventional forms of cutting:

  1. laser cuttingLaser cutting is a non-contact process, and so there is minimal damage caused to the material you are working with and associated moving parts
  2. Laser cutting has low maintenance costs and only needs inexpensive replacement parts
  3. The laser cutting process helps to dramatically reduce material wastage
  4. One laser cutting setup is capable of working with multiple materials and applications
  5. It is much safer using laser cutting than other processes as the beam is enclosed within a light box
  6. You are offered total control with the beam intensity, heat output and duration when undertaking a laser cutting process, making this a highly reliable process

These are just some of the many advantages of laser cutting. These benefits have led to laser cutting being used in numerous industries, including the automotive, aerospace, electronics, semi-conductor and medical industries.

WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF LASER CUTTING?

WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF LASER CUTTING?

Laser cutting, as the name may suggest, is the process of cutting a material using a laser beam. This can be done to either trim down a material or to help cut it into complex shapes that more conventional drills would struggle with. Now, let’s see some of the advantages and disadvantages that comes with this technology.
laser cutting1. Advantages Of Laser Cutting
1) It is easier to keep the work-piece in the right position.
2) Short obtained by laser cutting doesn’t take long and are extremely accurate. The whole cutting process is easily achieved in less time compared to traditional scissors.
3) As the section is produced, there isn’t direct contact of the work-piece with a cutting tool, lowering the risk of contaminating material.
4) In traditional separation process, the heat generated during the process of cutting usually melts the material. In laser cutting, the heat area is very small, reducing the possibility of material deformation.
5) The laser cutting machines require less energy for cutting sheet metal.
6) The laser cutting technology can be used to cut wide range of materials like wood, ceramics, plastic, rubber and certain metals.
7) Laser cutting is amazingly versatile technology and can be used to cut or burn simple to more complex structures in one piece.
8) One or two cutting machines are able to be used in the work of several other cutting machines.
9) Laser cutting process is easily controlled by computer programs, which makes it very precise while saving considerable amount of work.
10) Because the laser cutting machine doesn’t require human intervention, except for inspections and repairs, the frequency of injuries and accidents is very low.
11) Laser cutting machine has high level of efficiency and required design replicas are exact copies of each other.
laser cutting2. Disadvantages Of Laser Cutting
1) Efficiency and power consumption depends on the type of section that need to be carried out and nature of the laser. Usually, laser cutting have high energy consumption.
2) Laser cutting of plastic components can be expensive because when exposed to heat, plastic emits gas. For this reason, the laser cutting service provider should have well-ventilated room, which is quite expensive. Also, the gases released during the process of cutting plastic can be harmful and toxic.
3) Not all types of metals can be cut with laser cutting. For example, metals like copper and aluminum can’t be cut using this technology.
4) Production rate isn’t consistent. All depends on the type of material used, the thickness of the work-piece and the nature of laser cutting.
5) Setting of the temperature and the distance laser can lead to the combustion of some materials.
6) Human intervention is required just in case of repairs and trial runs. While these actions, worker comes in close contact with the leaser beam, which can cause burns.
The difference between  CO2 laser cutting machine and UV laser

The difference between CO2 laser cutting machine and UV laser

Definition of CO2 laser cutting machine:

CO2 laser cutting machine is a gas laser using CO2 gas as working substance. The discharge tube is filled with CO2, helium, nitrogen, hydrogen and xenon, mainly CO2 and others. High voltage on the electrode and discharge in the discharge tube have laser output on the germanium mirror.

The advantages of CO2 laser cutting machine:

There are abundant spectral lines, and there are dozens of spectral lines near the 10 micron laser output. The output beam has high optical quality, good coherence, narrow line width and stable operation. With relatively large power and relatively high energy conversion efficiency, the energy conversion efficiency can reach 30 to 40%, which is also higher than that of general gas lasers.

The working principle of CO2 laser cutting machine:

Principle of laser generation: The discharge tube of CO2 laser is filled with a mixed gas of CO2, N2, He, etc., and the ratio and total pressure can be varied within a certain range. CO2 lasers use the vibration between the CO2 molecules and the transition between the energy levels to generate laser light.

The applicable object of CO2 laser cutting machine:

CO2 laser cutting machine is mainly used for cutting non-metallic materials, such as cloth, the jeans we wear, some holes or old colors are processed through this CO2 laser cutting machine. There are also leather, plastic, acrylic and other can also use CO2 laser cutting machine. If the power is high, CO2 laser cutting machine can also cut metal. But the accuracy is generally not too high, and can not cut too thick. Compared with optical fiber laser cutting machine is still relatively inadequate, so the use of metal cutting is less.



Definition of UV laser:

Ultraviolet laser cutting machine is a cutting system using ultraviolet laser. It utilizes the characteristics of ultraviolet light and has higher precision and better cutting effect than traditional long wavelength cutting machine. The use of high-energy laser sources and precise control of the laser beam can increase processing speeds and achieve more accurate machining results.

Advantages of UV lasers:

High-performance UV lasers have short wavelengths, high beam quality, and high peak power. Reduce the size of the focused spot to ensure the processing accuracy, different thickness, different materials, different graphics can be cut.

The working principle of UV laser:

Except for free electron lasers, the basic working principles of various lasers are the same. The indispensable condition for generating laser light is that the ion number is reversed or the gain is greater than the loss, so the indispensable components of the device are the excitation (or pumping) source and the working medium with the metastable energy level. Excitation is the excitation of the working medium to excite the excited state, creating conditions for achieving and maintaining the population inversion. The incentive methods include optical excitation, electrical excitation, chemical excitation and nuclear energy excitation.

The applicable object of UV laser cutting machine:

UV laser is especially suitable for cutting and marking of hard plate, soft and hard joint board, soft plate and its accessories.
