With its adaptability, laser cutting technology can efficiently work with materials of different thicknesses, giving a great deal of leeway in processing various materials. The capacity to accurately and precisely cut through a broad variety of material thicknesses is a key advantage of laser cutting. Laser cutting machines are versatile and can be adjusted to handle materials of varying thicknesses, making them suitable for a wide range of industries.
How well laser cutting machines work with materials of different thicknesses is highly dependent on the laser's kind and power output. Because of its ability to produce higher power levels, CO2 lasers are particularly good at cutting through denser materials like metals, plastics, and woods. Conversely, fibre lasers are ideal for elaborate designs and smaller cuts due to their remarkable precision and efficiency while cutting thinner materials.
The power, focal length, cutting speed, and beam intensity of the machine, in addition to the type of laser, determine the machine's versatility in cutting materials of varying thicknesses.
Regardless of the thickness of the material, these characteristics can be fine-tuned to obtain ideal cutting results on a wide variety of materials. Laser cutting technology is highly favoured in businesses that frequently deal with materials of differing thicknesses. It provides precision and versatility in production and design processes, making it an ideal choice.
Different kinds Laser Cutting Equipment
There are many varieties of laser cutting machines, and each one has its own maximum thickness that it can cut. A fibre laser cutter and a CO2 laser cutter are the two machines in question.
CO2 Laser Cutters
The most common type of laser cutting machine is the CO2 laser cutting machine. Although it's very inexpensive, a new fibre laser cutting technology that uses state-of-the-art machine components is quickly replacing it.
A long gas-filled tube with a vacuum sealer at its base makes up this laser cutter. For this purpose, CO2 is typically prioritised. Nitrogen gas is combined with carbon dioxide gas. By activating the gas molecules, the tube generates a powerful light when an electrical connection is made to it.
A set of mirrors serves to reflect the light and then refocus it onto the focusing lens. Therefore, by concentrating the lens on a hot spot, the light is concentrated. It causes materials to be cut to different thicknesses according to their maximum thickness and thermal separation.
Sheet metal fabrication makes use of a CO2 cutting machine. Using this cutting machine, metals with a maximum thickness of 0.25 inches can have their edges ground to perfection. There is a limit to how much the CO2 cutting machine's laser can cut.
Fibre Cutting
Fibre optic light and the fibre laser cutting machine actually work in tandem. This fibre laser cutting machine outperforms its competitors in terms of cutting ability. Light enters the fibre machine through a glass tube coated with many varieties of glass, each with its own unique reflecting qualities.
While this fibre laser equipment usually doesn't require much maintenance, it does have a few moving parts that could use adjustment or repair. Cutting with a fibre laser requires a lot more space and money than with a CO2 laser. If you want to know how fibre lasers and CO2 lasers differ, click here.
The cutting machine's laser has a smaller diameter because of how fibre optics work. As a result, the fibre cutting machine is useful for getting a precise result.
Metals that are difficult to cut using conventional tools, such as:
- Carbon steel plate
- Material: stainless steel
- Carbon steel sheet
- Metal sheet
- Metallic sheet
A fibre laser's superior cutting power applied to a copper plate.
The thickness of the aforementioned materials can differ. The real cutting power or capacity of these devices is substantially more than that of CO2 laser cutting machines.
Lasers Cutting
Power laser machines are top-of-the-line tools for cutting through extremely thick materials with lasers. According to the thickness of various materials, they have cutting machines with varying cutting capacities.
A laser cutter, when operated correctly, may create a safe cutting environment while precisely cutting materials up to their maximum thickness. A wide variety of materials can be bright-surface cut using power laser equipment.
You won't find the same laser in these machines. A wide variety of materials with varied or uniform thicknesses were machine-cut, including copper, aluminium, stainless steel, carbon steel, and many more.
The Materials For Laser Cutting
The fibre laser cutting machine's powerful fibre lasers allow it to cut a variety of materials. The latest fibre lasers are capable of cutting materials as thick as 2 inches. Cutting 1" steel, 1.5" aluminium, and stainless steel is often within the capabilities of an 8KW fibre laser.
The material's variability is utilised for cutting. Plates of aluminium, stainless steel, mild steel, carbon steel, and thick steel are among the metals that are frequently laser cut using this. Cutting carbon steel and copper plates is also a breeze with this machine. There may be thickness restriction values for the various metals listed earlier.
Aluminium
When compared to steel, aluminum's weight and pliability are far more appealing. For this reason, aluminium plate is a popular material for clean laser cutting. A 500 W fibre laser cutting machine can handle aluminium plates up to 2 mm thick.
Stainless Steel
Stainless steel is made by adding trace amounts of chromium to steel. Stainless steel is an excellent cutting material because it resists corrosion. Stainless steel does not corrode or rust. For a 500 W fibre laser cutting machine, the greatest thickness of stainless steel that can be cut is 3 mm. Here you may find a detailed tutorial on how to cut stainless steel using a laser.
Mild Steel
Due to its lower carbon concentration power, mild steel is often prefered for cutting purposes over carbon steel. It is easier to cut when the carbon level is low.
Carbon Steel
Steel is a product of carbon and iron working together. Because of its high carbon content, carbon steel is both strong and easily shaped. The carbon steel may be precisely sliced with the laser's flawless cutting surface.
Other Alloys Steel
The alloy steel is reinforced through bonding with other elements, making them suitable for use with laser cutters.
Non-Metal
Cuts can be made in a variety of non-metallic materials, including ceramics, plastics, wood, and metal sheets. But they aren't quite as strong as metals.x
What Kind of Equipment Is Used for Laser Cutting?
Laser cutting machines come in a wide variety of variants, from hobbyist versions to ones specially designed for use in large-scale industrial manufacturing. When it comes to cutting lasers, there are three primary varieties.
The type of laser that is utilised in the cutting machine will determine the machine settings for a particular material. Below is a list of the three different kinds of laser cutters:
- CO2 Lasers: CO2 lasers generate a laser beam by running an electric current through a tube that is filled with a gas mixture. Typically, this gas mixture is composed of helium, nitrogen, hydrogen, and carbon dioxide. The tubes have mirrors on both ends; one is completely reflective and lets light through, while the other is just half reflecting. This light passes through the partially reflected mirror, gets increased after reflecting off the mirrors, and is then utilised to cut and engrave parts. Although CO2 laser cutting machines are capable of cutting a wide range of materials, they are most frequently used to cut acrylic, paper, wood, and paper-based items. The materials that these lasers work best on are non-metallic.
- Fibre Lasers: Fibre lasers employ specific glass fibres that receive energy from pump diodes to form the laser beam, as opposed to CO2 lasers, which use electric current, a gas mixture, and a series of mirrors. Out of the three types of lasers, fibre lasers are the most costly. They can be operated for up to 25,000 hours with minimal maintenance. Although they can work on any material, metallic or non-metallic, these lasers are best suited for engraving metal and thermoplastic.
- Lasers Nd:YAG/Nd:YVO - The crystal that was utilised to produce the laser beam is referred to by the descriptive labels Nd:YAG (neodymium-doped yttrium aluminium garnet) and Nd:YVO (neodymium-doped yttrium ortho-vanadate). These machines can be very costly, but they offer cutting power that is unmatched when it comes to cutting reflective metals, including coated and uncoated metals, as well as non-metals like plastics and even ceramics.
What Protective Equipment Is Necessary For Laser Cutting?
Workers should wear protective gear while operating a laser cutting machine to avoid eye damage, burns, and fumes. Lasers are intense beams of light that can cut through solids and leave an engraving in their wake. Wearing the appropriate laser eye protection is crucial for preventing harm to the eyes. Wearing protective eyewear that blocks the laser beam's wavelength allows them to do their job.
Also, make sure the laser cutter has enough air circulation. Some materials, when cut with a laser, release toxic vapours known as "laser-generated air contaminants," or LGACs. There needs to be adequate ventilation in the area around the laser cutting system in order to remove any toxic gases that may be produced, including benzene, hydrochloric acid, and toluene.
The presence of laser cutters increases the risk of fire, so it's important to have a fire extinguisher close at hand. Use the laser system only on the specified settings, never leave it running unsupervised, and keep the area surrounding it clean at all times to avoid fire hazards.
