Laser Cutting

Laser cutting is a technology that uses a beam of high intensity light to cut through nearly all objects, with the rare exception of mirrors and other extremely polished surfaces. Laser is the acronym of Light Amplification through the Simulated Emission of Radiation. In this process, a laser gun sends out bursts of light of wavelengths from 380 to 740 nm to cut through objects. The three different colours of laser are green yellow orange, and red, and the colours depend on the frequency of the oscillation of the light (frequency).

What is laser cutting?

In this process, an individual uses a special gun that generates a high intensity beam of energy to cut through steel, wood, glass, and many other objects. These beams are accurate and it is possible to adjust their power based on requirements. A simple example is its employment in surgeries for emulsifying the internal lens of the eye to remove cataracts, using a surgical process known as phacoemulsification. Surgeons also use accurate laser cutting for removing haemorrhoids, which is much quicker and better than "stapler" or "cryo" methods.

Why do people need laser cutting?

People need this method, as it is extremely accurate and can cut objects to the order of a nanometre or even less with extreme precision. The biggest advantage of using this method for cutting objects is that one can program the beam before the cutting procedure using a simulation method in which the cutting area is recorded on the gun. Once done the laser follows the path input in the computer.

What are the benefits of accurate laser cutting?

People prefer this method when they want to do extremely precise cutting jobs. The highly precise and accurate nature of laser cuttings is unarguably one of the greatest benefits this method has provided to users. This beam allows for extremely accurate cutting, which leaves a smooth and clean cut finish. Many industries also use lasers for a wide range of applications such as welding, cutting, and drilling. No other known method of cutting offers such a precise and smooth finish that laser offers.

Who would need laser cutting?

As mentioned above, surgeons who want to carry out delicate surgery that was previously impossible use this method to complete the process. Cataract and haemorrhoid surgeries that were painful and time consuming and where the wounds took several days to heal can now be completed in less than an hour with the help of lasers. Industrialists use them for precise cutting, drilling, and welding jobs.

What is the laser cutting process?

This is a thermal process in which the focussed beam of light melts material in a localized zone and nitrogen at high pressure is used to blow the molten metal out of the slit. In CNC laser cutters, operators move the cutting head over the metallic plate along the desired path, cutting the part out of the plate in the process. Laser beams can be used to cut a wide range of objects including plastics, thin metal sheets, depron foam, magnetic sheets, suede, leather, hemp, and much more.
