Disadvantages of laser cutting

Category: ServicesThe use of lasers in industry has enabled innovative applications in all sectors. It offers many advantages over other processes, such as material savings, higher production speed, precise cutting and high quality results. In addition, this thermal separation process is flexible and easily automated.

This sheet metal and tube metal cutting technique uses the laser as the main tool, through a fully robotized drive. Mechanical pressure and contact on the material is eliminated, making highly precise cuts with a nozzle-directed laser. A precise system of mirrors and a focusing lens guides the light beam to the cutting head of the machine. Once it comes into contact with the surface of the workpiece, it heats it until it melts or vaporizes. The beam follows the chosen silhouette and separates the material, thus generating precise cuts.

How does laser cutting work?

Laser cutting is a type of thermal separation process. The laser beam strikes the surface of the material and heats it so strongly that it melts or vaporizes completely. Once the laser beam has completely penetrated the material at one point, the actual cutting process begins.

What are the benefits of laser cutting?

The advantages of laser cutting make it the best process for demanding results: High precision and level of detail: it can handle complex cutting profiles as well as very small bending radii. There are hardly any burrs, as the cuts are very clean.

What is the hourly rate for laser cutting?

Taking into account the process of operation of these laser cutting machines, the most logical for us is to charge the service by time of work of the machine, plus the consumed area of material in case it is required. For example, the service will be charged at $10 pesos per minute of work.

How laser cutting works

Laser cutting is the technique by which steel is separated or divided by heating it to melting temperature. This process is achieved through two simultaneous processes: the stimulated emission of radiation, and a stream of CO2 at very high pressure. The section of material thermally affected by the radiation is very limited, which avoids distortion of the material and changes in its physical properties.

The laser beam is a fast, clean and precise multifunctional tool that can machine the most diverse materials, cutting parts of simple or complex geometry. In addition, it allows us to offer agile responses to changing requirements and demands.

The precision of the cut and the lack of mechanical contact with the workpiece significantly reduce the occurrence of distortions and impurities. Burrs disappear and subsequent cleaning work is avoided.

Which is better, laser or plasma?

The quality of laser cutting is optimal in thicknesses of around 15-20mm. For thicker thicknesses, the quality of the cut decreases significantly. Plasma cutting allows high definition and cutting quality, guaranteeing high precision finishes.

What does the laser cutter cut?

Laser beam cutting (LBC) is a thermal cutting process that uses highly localized melting or vaporization to cut metal with the heat of a coherent beam of light, usually with the assistance of a high-pressure gas.

What type of gas is used in laser cutting?

The introduction of laser melt cutting in production is very recent. The material is melted by the laser beam and swept with a stream of non-reactive gas, which in most cases is usually nitrogen, although argon is also sometimes used.

Ultra-short pulse lasers evaporate almost any material so quickly that no thermal influence is noticeable. Thus, high-quality cut edges are generated without the appearance of casting. The lasers are therefore particularly suitable for the manufacture of intricate metal products such as stents in medical technology. In the display sector, ultra-short pulse lasers cut chemically hardened glass.

How does waterjet cutting work?

The water jet with abrasive is generated in the same way as the pure water jet, but before escaping through the cutting head, the Venturi effect generated in one of the parts of the cutting head drags the abrasive, which ends up mixing with the water jet.

How is cutting plasma generated?

The basis of plasma cutting is based on raising the temperature of the material to be cut in a very localized way and above 20,000 °C, taking the gas used to the fourth state of matter, plasma, a state in which the electrons are dissociated from the atom and the gas is ionized (becomes conductive).

How much does laser cutting cost per minute?

Cost and payment for laser cutting: – The cost is $3.00 per minute. – The cost is calculated based on the time timed by the equipment + the time spent correcting or modifying your file.

Laser cutting advantages and disadvantages

There is enormous competition in the market between different cutting technologies, whether for sheet metal, tubes or profiles. There are those that use mechanical abrasive cutting methods, such as water jet and punching, and those that use thermal methods, such as oxyfuel, plasma or laser.

However, with the recent irruption in the laser world of fiber cutting technology, this technological competition is being fought in high-definition plasma, CO2 laser and the aforementioned fiber laser.

Which is the most economical, the most accurate, for what type of thickness and material? In this post we are going to explain the characteristics of each one and be able to choose the one that best suits our needs.

This technology is the most suitable for carbon steel in considerable thicknesses (75mm). On the other hand, it is not effective for stainless steel and aluminum. It has a great portability, since it does not need a special electrical connection, and the initial investment is low.
