What is a Laser Cutter and How Does it Work?

Laser cutting technology is mostly used in the manufacturing sectors by engineers and designers although this is becoming increasingly popular amongst small businesses, schools and hobbyists alike. Laser cutters have a lot of benefits and applications and in this article, I would be talking about what a laser cutter is and how it does work.

What is Laser Cutting?

Laser Cutting is the process whereby a laser beam is used for cutting and piercing through materials so as to cut out complex shapes, patterns, and geometries that have been specified by designers. The materials that can be cut using a laser cutter range from light materials like clothes, paper, and wood to tougher ones such as metals and gemstones. Laser cutters help to deliver an accurate and smooth finish due to the high level of control that it offers.

Types of Laser Cutters

There are three main types of laser cutters; fiber laser cutters, CO2 laser cutters, and the crystal laser cutters.

Fiber Laser Cutter

Fiber lasers belong to the solid state group and are made from “seed laser” which is amplified using special pump diodes and glass fibers. These lasers are mostly employed in the laser marking processes. They can be used to cut both metal and non-metal materials such as plastics and metals. Fiber lasers are cheaper to maintain and they tend to last longer compared to other types.

CO2 Lasers

This type of laser is the most commonly used of the three types of lasers that we have, this is due to the fact that they are relatively inexpensive and they can be used to cut a wide variety of materials.

Crystal Laser Cutters

There are two types of lasers used in this process; the neodymium-doped yttrium aluminum garnet (nd: YAG) and the neodymium-doped yttrium ortho-vanadate (nd: YVO). These crystals have a wavelength of about 1.064mm which makes them suitable to cut both metals and non-metals. Crystal laser cutters are costly to maintain as they are made from expensive pump diodes which cost a lot to replace.

How Does a Laser Cutter Work?

Laser cutters can cut metal with high temperatures and make complex shapes but how do these lasers work exactly? Well, it starts with the use of two mirrors; a gain medium and a light source. Light enters the gain medium and excites the atoms inside to a higher state, after a while the atom would drop back down to the original state to emit a photon. The photon then creates a chain reaction which makes the other excited atoms emit their photons; soon we have a bunch of photons bouncing back and forth between these two layers. Since when the mirrors do not have a reflectivity of 100% some of the photons will pass through and create a laser. Now, that is a general concept of how lasers work.

Laser cutting is a very reliable and accurate cutting process and its benefits cannot be overemphasized. Laser cutters can cut precise shapes into metal with the use of laser beam machining in ways the traditional machining processes cannot that’s the beauty of lasers.…

How Does Laser Cutting Work? Why lasers are used for cutting

The laser cutter is used for most purposes. One of many ways they are used is for slicing metallic plates. On minor steel, stainless, and aluminum dish, the laser trimming process is highly correct, yields excellent lower quality has an extremely small kerf width and small heating affect zone, and makes it possible to cut very complicated figures and small openings.

Most people know that the term “LASER” is actually an acronym for Light Amplification by Stimulated Emission of Radiation. But how can light cut by having a steel plate?

How it laser cutter works?

The laser is a column of very high-intensity light, of a single wavelength, or color. In the case of a typical CO2 laser, that wavelength is in the Infra-Red area of the light spectrum, so that it is unseen to the eye. The beam is merely about 3/4 of the inches in diameter as it travels from the laser resonator, which creates the beam, through the machine’s beam path. It may be bounced in various directions by lots of mirrors, or “beam benders” before it is finally concentrated onto the dish. The focused laser beam undergoes the bore of any nozzle before it visits the dish. Also flowing during that nozzle bore is a compressed gas, such as Air or Nitrogen. Click here.

Why you need a laser cutter?

Focusing the laser beam can be done by a particular lens, or by the curved mirror, and this occurs in the laser beam cutting brain. The beam needs to be precisely focused so the shape of the concentrated spot and the denseness of the vitality in that place are perfectly round and reliable, and focused on the nozzle. By focusing the large beam right down to a single pinpoint, heat thickness at that location is extreme. Consider using a magnifying glass to focus natural sunlight onto a leaf, and how that can start an open fire. Now think about concentrating 6 KWatts of energy into a single spot, and you may imagine how hot that spot will get.

Burning up the process?

The high-power thickness results in immediate home heating, melting and partial or complete vaporizing of the material. When cutting gentle steel, the heat of the laser cutter is enough to begin a typical “oxy-fuel” burning up the process, and the laser slicing gas will be natural oxygen, just like an oxy-fuel torch. When slicing stainless or lightweight aluminum, the laser cutter beam simply melts the material, and high-pressure nitrogen can be used to blow the molten metallic out of the kerf.

  • On the CNC laser cutter, the laser cutting head is moved on the metal plate in the condition of the required part, thus reducing the part from the dish.
  • A capacitive level control system maintains a very appropriate distance between your end of the nozzle and the plate that is being sliced.
  • This distance is important since it determines where in fact the center point is in accordance with the top of the plate.
  • Lower quality can be damaged by elevating or cutting down the center point from right above the surface of the plate, at the top, or just below the top.

There are many, many other guidelines that affect slice quality as well, however, when all are managed properly, laser cutting is a stable, reliable, and incredibly accurate clipping process.
