Benefits Of Laser Cutting
Although laser cutting is not a new process, it has undergone significant advancements with the help of modern technology, particularly Fiber Lasers and Direct Diode resonators, which have significantly reduced maintenance and operating expenses associated with CO2 systems used in the past. Laser cutting is an incredibly versatile and efficient method of metal fabrication that is widely used for manufacturing parts, regardless of their complexity. By using lasers, various materials, including wood, metal, plastic, and rubber, can be thermally cut with high precision, with accuracies down to three decimal places, without any direct contact with the material.
What is laser cutting?
Lasers have a wide range of applications, including hair removal and surgical procedures. The fundamental principle behind lasers involves magnifying light to the point where the generated heat can liquefy or vaporise materials. Laser power is typically measured in KW, ranging from 2-6KW presently, while high-speed heavy plate cutting systems can reach over 40KW. Lasers are utilised to inscribe or carve designs into specific materials, and thanks to advancements in technology, they can be programmed to produce any desired shape.
How does laser cutting work
A laser is a powerful tool that uses a focused beam of light to cut through materials by producing intense heat. The term "laser" stands for Light Amplification by Stimulated Emission of Radiation, and it is capable of cutting metal due to its high intensity in a single wavelength. If a CO2 laser is used, the wavelength falls in the Infra-Red range, making it invisible to the human eye. The laser beam travels through a gas-protected pathway from the laser resonator to the cutting head, which reflects the beam through several mirrors, increasing its intensity before reaching the target. Additionally, compressed gas, such as Oxygen or Nitrogen, surrounds the beam, protecting the material and intensifying the burn.
Benefits of Laser cuttings
When given the option, the majority of individuals prefer utilising laser technology for cutting tasks as opposed to alternative methods due to the numerous benefits associated with laser cutting.
Versatility
With a laser, various materials can be processed without the need for multiple machines, making it an efficient option for diverse product manufacturing. The laser can be easily programmed to cut through materials such as carbon steel, stainless steel, and aluminium, as well as for marking or etching product information, serial numbers, dates, revision numbers, assembly instructions, or branding on surfaces. Additionally, only the nozzle needs to be changed depending on the application, rather than the entire tool.
Precision
Laser cutting is highly advantageous due to its exceptional precision, which eliminates the need for any post-cutting adjustments. The laser's programming ensures that it cuts identical patterns every time with pinpoint accuracy.
Speed
In comparison to alternative cutting methods, laser cutting is significantly faster, especially for intricate designs. This is due to the absence of an additional tool setup, which expedites the production process.
Cost Effective
The machine can be utilised for almost all kinds of materials without the need for additional tools. Also, there is minimal or no waste/scrap to be thrown away.
Customisation
The laser machines can be tailored to cut whatever material is required and can be automated, minimising the possibility of human error. There are numerous customisable options available, and the machine's payback period can be divided into three shifts in a production day.
