Laser Cutting Technology

The abbreviation of the word ‘Laser’ is ‘Light Amplification by Stimulated Emission of Radiation. In laser cutting technology, a ‘laser beam’ is an extremely intensive radiation wavelength that will never disperse uses to cut the metal materials, the sheet metals, iron, nickel, stainless steel, aluminum, brass etc. Laser cutting provides high precision as compared to any other metal cutting technology. A laser beam is generated or directed at the material through optics and computer numerical control (CNC). For commercial scale, laser beam utilizes a flow control system to follow CNC for the cutting pattern on the target material. A laser beam focuses on a target material that cuts down the material either by burning, melting, blowing, or vaporizing away through a gas jet resulting in a cut edge leaving a smooth surface finishing.

Applications of Laser Cutting

Besides slicing, cutting, burning, melting, vaporizing, or blowing away materials, a laser also provides different services including macro and micro-machining like laser etching, laser welding, laser drilling, and laser engraving.
This advanced technology is operational mostly in industrial regions requiring microscopic tolerances and scrupulous precision including electronics and micro-technology. It is also useful in locomotive manufacturing, medical devices, military, plumbing, and HVAC.

History

In the early 1900s, Albert Einstein presented the theory of laser technology while in the 1960s, Theodore H. Mainman invented the first laser cutting machine that was a pink-ruby laser in a solid form. In New Jersey, an engineer named Kumal Patel produced the first laser machine based on CO2 gas four years after the invention of the former laser machine. In 1965, Western Electric Engineering Research Center developed the first laser metal cutting machine that was used for drilling the holes in diamond dies. In the 1970s, laser cutting technology was operational all around the world, and the application of laser cutting could be seen in all kinds of cutting from textile cutting to titanium cutting.
In recent times, laser cutting services make up the leeway as we know carbon dioxide (CO2) lasers are now as strong as they can easily cut any metal material while they were unable to perform the same task in the 1970s. At present time, laser cutting services are economical, more effective, providing more accurate cuts, and are more versatile. With time, the characteristics and qualities of laser cutting services will progress more and become more efficient.

• Technicians direct the focused laser beam on the particular area that is required to cut by using CNIC control alone or in combination optics.
• In some cases, we combine a gas N2 or CO2 to assist with laser cutters for painting or erosion resistant coating of the recently cut material surface. Nowadays, CO2 is considered the strongest wave laser all around the world.

Laser Cutting Parts

Laser cutting machines generally comprises a main machine, light, and electric power. There are thirteen auxiliary laser cutting parts viz., frame of laser cutters for stability of the machine, laser generator for providing laser light, lenses for focus or full reflex, CNC system for the control of machine movement along an axis or output power of laser cutting, regulated power supply for maintaining the connection among laser cutter, laser generator and CNC system and preventing the intervention of any external power, control platform for the control of the whole laser cutting machine, laser cutting head for the movement along z-axis, motor is the main part of motion system, water chiller to cool the laser generators, gas cylinders for supplying auxiliary gas for the movement of laser cutting head, air compressor for storing and providing compressed air, air cooling dryer for supplying filtered and dry air to the laser generator, dust extractor for extracting the dust and smoke produced during the processing, slang discharge machine for the elimination of discarded material during the processing.

Machinery Used for Laser Cutting

Generally, different types of laser cutters are used for laser cutting purposes. The types of laser cutting including metal lasers, fiber lasers, Neodymium (Nd) lasers, Neodymium yttrium-aluminum-garnet (Nd: YAG) lasers, carbon dioxide (CO2) lasers, and high-powered lasers are described as:

Metal Lasers: As the word describes, this type of laser is specifically designed for sheet metal laser cutting. Metal lasers generally cut or treat metals such as stainless steel, mild steel, carbon steel, titanium, and scribing metals.

Fiber Lasers: This type of laser is treated with rarely known earth elements like thulium, erbium, ytterbium, and is dependent on optical fiber. Fiber lasers are known for their immobile parts, easy maintenance, cost-effective operations.

Neodymium (Nd) Lasers: This is a type of fiber laser that is designed for operations requiring high energy and low repetition like boring applications. They can also be used for purpose of laser welding and this is the best laser type for some metals like scribbling and ceramic metals.
Neodymium yttrium-aluminum-garnet (Nd: YAG) Lasers: This is also a type of fiber laser and resembles a lot with Nd lasers. This type performs the best etching, engraving, and boring application with high power. Additionally, they can also perform laser welding.
CO2 Lasers: This is a versatile type of laser that can easily cut a broad range of materials from stainless steel sheets to wood to paper sheets. Initially, it was used for various operations like material cutting, engraving or etching, and boring. Some subtypes of carbon dioxide laser such as slow axial flow laser, slab laser, transverse flow laser, and fast axial flow laser are also available.
High Power Lasers: This type of laser cut the materials same as by metal lasers and are designed specifically for cutting strong metal material like mild steel, stainless steel, scribbling metals, and carbon alloys. High-power lasers have double strength comparing many other types of laser cutters.

Our Custom Machined Parts Production

As the world progresses and the latest technologies are developing, the requisition for custom machined parts or enclosures is enhancing. The requirement of the latest models of particular machines with unique parts reveals that the purpose is also highly demanding. Before getting aware of demanding purpose, it is unable to design the required machine parts or enclosures with such accuracy that their dimensions and measurements can meet consistently with standard measures of any purpose. That is why they are required to be developed specifically for the particular purpose of the demand. In some cases, the demand of the client is about the same machine parts but with varying dimensions and sizes. Our company excels in completing high-precision jobs using our cutting-edge technology. The demand for machine part size varies as per customer’s demands and needs. The creation of custom machined parts with unique sizes, shapes and dimensions require cutting procedures that can effectively create the custom machined parts while meeting all the standard measures. Custom laser cutting is such a technique used for cutting the required machine parts in desired shape and size. This technique involves an intense beam of laser with heavy density directly focused on the target metal or metal that is attached with a CNC system for the achievement of the required shapes and designs.

Our Custom Laser Cutting Services

Custom laser cutting is a cutting process to precisely remove the raw material from the metal materials or cut metal sheets in any required shape by involving a laser beam0 associated with a CNC system. This process requires optics to focus on electrical energy in the form of a laser beam with high density. The required shapes are achieved after melting, burning, blowing, or vaporizing away the processed metal through O2 or N2 jets. The application of laser cutting is perfect to rapidly create custom parts taking work pieces out of metal sheets, scribing metal, aluminium, brass, thin stainless steel, carbon steel, mild steel, copper alloy, sterling silver, bronze, card stock, rubber, acrylic, or wood. After drawing the required design on a computer, the customized image will be engraved easily on a metal sheet or other material. Custom laser cutting offers to create complicated designs that are very intricate to make the image manually. Custom laser cutting also offers to cut even curves and can evenly etch any text, logo, or monogram on the surface of any material.
We want our clients to be well familiar with the services that are being provided so that they are capable of making the most suitable decisions about their choice and take the guideline from the company about the requirements of metal sheet laser cutting.

Folding, Bending, and CNC machining

Just cutting the target metal material like aluminium, stainless steel, the copper alloy does not accomplish the requirements of a specific shape. After cutting the metal sheet, the desired shape by folding and bending is also required. Many machines are used for bending or folding the sheets of metal into various shapes to meet the clients’ requirements of a specific shape. We are using computerized numeric control (CNC) for bending, milling, and turning. So, CNC machining is one of our services.
The folding or bending of a metal material is one of the most important and essential phases during the manufacturing process. Generally, the implementation of an external force can be observed during the folding and bending of the metal sheet material along a certain axis. This applied force is responsible for generating the required alteration in the geometry of metal material.
The volume of the metal sheet does not change and remains constant, while the shape of the metal sheet changes as per requirement. However, the folding and bending do not affect the thickness of the metal sheet.
