What Are the Disadvantages of Laser Cutting

Although CNC metal laser cutting machines improve production efficiency and save labor for the industrial market, they also have some disadvantages. This article will provide an informative description of them.

The disadvantages of metal laser cutting in the convenience of cutting technology

Cutting limitations:

Do not cut too thick plates, because different power has a certain cutting limit. For enterprises that cut more thick plates, it may be necessary to purchase 2-3 laser cutting equipment to meet demand.

The cost is high:

The higher the power, the greater the thickness of the cutting, and the higher the cost, which is a significant expense for some enterprises.

Material limitations:

For highly reflective copper or aluminum, special fiber lasers are required.

Environmental factors:

Affected by the surrounding environment, consumables such as focusing mirrors require regular maintenance.

Safe operation:

Operators need to strictly follow the operating instructions and receive professional technical training, as lasers can damage people’s eyes and require goggles and protective masks.

Harmful gas

When laser cutting plates, harmful gases are generated, causing certain environmental pollution. Additionally, a delayed dust removal device is required, which increases the cost.

Professional technology

The operators of the production enterprise cannot operate the laser equipment by themselves, and the laser equipment factory needs to arrange professional technicians for professional and systematic technical training.

Health hazards

The harm caused by the laser cutting machine to people may cause skin or eye damage. Sparks are usually produced during use, which can irritate the eyes, cause stinging, and affect normal vision. During use, it can also cause skin damage and easily lead to a decrease in tissue repair function.

Long-term use will produce a large amount of dust, causing damage to the lungs and respiratory system, and easily causing breathing difficulties or lung lesions.

Personal care should be taken during use, and glasses and masks are usually required to reduce harm.

  1. The new contact laser cutting machine likes to stare at the cutting head. Sparks from cutting can cause eye damage and sting if you look at them for a long time. The optical refractive medium is focused on the retina to form an image, and compared with the incident energy density on the cornea, the energy density on the retina is increased by 104 to 105; the laser has good monochromaticity and small fundus chromatic aberration. Resulting in extremely low laser energies that can cause corneal or retinal damage. Eye protection or a protective shield should be worn.
  2. It usually causes damage to the skin or eyes. Sparks are generally produced during use, which can cause eye irritation and stinging, and can also affect normal vision. It can also cause skin damage during use, which can easily lead to a decrease in tissue repair function. At the same time, long-term use can produce a large amount of dust, which can cause damage to the lungs and respiratory system, and can easily cause breathing difficulties or lung lesions.
  3. During the processing process, the characteristics of the laser emitted by the laser cutting machine can make the energy highly concentrated in space and time. It is focused on the retina through the refractive medium of the eye to form an image. The energy density on the retina is increased by 104 to 105 compared with the incident energy density on the cornea. The laser has good monochromaticity and small chromatic aberration in the fundus. The above characteristics result in extremely low laser energy irradiation that can cause damage to the cornea or retina. During use, personal care must be taken, and glasses and masks are generally required to reduce damage.

The occurrence of fiber laser cutting machine accident

Many laser operators cause fiber laser cutting machine accidents due to improper operation or non-human factors, so Laser Cutter Safety needs to be strictly observed.
