Brief Introduction to Laser Cutting Machines

In recent years, metal cutting was done using specialized saws and traditional methods, which were very time-consuming and exhausting. Today, with technological advancements, laser cutting machines are used, making the work much easier. Working with these machines has increased work speed, minimized errors, and allowed for more complex designs. With the advent of laser cutting machines, the quality of work has greatly improved, and the cleanliness of the cuts has also increased, eliminating sharp edges and extra cut sections.

Types of Laser Cutting Machines

There are various types of laser cutting machines, but the most common ones are:
CO2 Lasers: This type of laser uses carbon dioxide gas to generate the laser beam. CO2 lasers are suitable for cutting a wide range of materials, including acrylic, wood, fabric, and plastic.
Fiber Lasers: This type of laser uses an optical fiber core to generate the laser beam. Fiber lasers are highly efficient for cutting metals and can cut thicker materials than CO2 lasers.
Nd:YAG Lasers: This type of laser uses a yttrium aluminum garnet crystal doped with neodymium to generate the laser beam. Nd:YAG lasers are suitable for cutting a wide range of materials, including metals, plastics, ceramics, and organic materials.
Ruby Lasers: This type of laser uses a synthetic ruby crystal to generate the laser beam. Ruby lasers are suitable for cutting metals and other hard materials.

Here are some additional tips for choosing a laser cutting machine:

Laser Power: Laser power is measured in watts. Higher laser power allows you to cut thicker materials or cut materials faster.
Cutting Area: The size of the laser cutting area is measured in inches or millimeters. The cutting size determines how large the materials you can cut in one go.
Table Type: There are various types of laser cutting tables. The table type you choose depends on the type of materials you want to cut and the size of the materials.
Additional Features: Laser cutting machines can come with a range of additional features such as fume extraction systems, autofocus systems, and automatic loading and unloading systems.
When choosing a laser cutting machine, it is important to consider your needs and budget. Laser services in metals are used in industries for designing and engraving on metals such as gold, silver, brass laser cutting, aluminum, platinum, copper, and others.

These machines, like other devices, have advantages that have made them popular for use, which are as follows:
Fast project delivery
Accurate and orderly metal cutting
Delivering work with no defects
Increased work speed
Hassle-free cutting of various iron, aluminum, copper, and steel sheets
Very little burr production during cutting
Less waste produced
Can perform complex cuts on various metals in the shortest time.

To perform metal laser cutting, the laser beam is first prepared. Initially, the raw materials used for laser generation are placed in the machine's laser generator, and then they are stimulated using electrical current or other methods. The laser-generating materials are stimulated through electrical current or a lamp's radiation, and the generated beam is reflected using mirrors in the machine to acquire the necessary energy for cutting. The beam is then focused on the target point through a lens located at the device’s head, which can shrink the beam to a size as small as 0.23 mm.

This cutting process allows you to achieve smooth, flawless cuts without any burrs. To cut metals using laser, materials such as CO2, ND, and ND-YAG are used, and the appropriate material should be chosen based on the type of work you intend to do. CO2 is used for cutting metals, while YAG is used for both cutting and engraving. To prevent the heat generated from damaging the machine, a cooling system is used, transferring the heat outside the machine and reducing the internal temperature through water cooling.

History of Laser Cutting

Laser cutting was first introduced in 1965 by creating holes in diamond molds for use by artisans. The first laser machine was developed by the Western Electric Engineering Research Institute. This early machine was a CO2 type, which had limitations in its structure, preventing it from cutting metal sheets, metallic objects, or steel.
The initial design of this machine was intended for industries working with leather, textiles, decoration, wood, and plastic. In CO2 laser cutting, the thermal conduction process was not powerful enough for cutting metals, so it could only be used for objects where thermal conduction did not occur when the laser beam was applied. These limitations do not mean that CO2 lasers were completely impractical, as they are still widely used in industries such as wood, MDF, plastic, plexiglass, leather, and fabric.

Evolution of Laser Cutting Machines

In 1967, the United Kingdom took measures to overcome these limitations and designed and produced the first machine using oxygen jet technology. This machine was capable of cutting metals. This invention led to a revolution in industries working with metals and helped increase the speed and quality of metal part production.
Laser cutting technology made significant progress in manufacturing parts for various industries, such as aerospace, automotive, electronics, pharmaceuticals, production engineering, and the military. In the early 1970s, oxygen jet cutting technology was used to cut titanium metal in the aerospace industry. This allowed for rapid adoption in various industries, and it became a standard practice. What was once limited by technological constraints is now available with the highest quality and speed, allowing producers to significantly increase their output.
Today, no car can be found that hasn’t used this technology in its manufacturing and assembly, as at least one metal part has been cut using laser cutting. With the development of laser cutting machines, other technologies have been introduced to the market, and industries now select the laser type that best suits their needs and working methods. Currently, the most commonly used methods for cutting metal sheets and iron laser cutting worldwide and in Iran are oxygen jet, fiber, and water jet technologies.
