CNC Laser Cutting Machine

A CNC laser cutting machine is a computer numerically controlled (CNC) laser cutting system used widely in the sheet metal manufacturing process carried out by laser cutters. CNC laser cutters are capable of making different and numerous intricate shapes not possible by conventional methods.

A CNC laser cutter machine is a computer numerical control (CNC) system which uses a high-powered focused laser beam to cut material to form custom shapes. The CNC laser cutter machine is very quick and highly accurate, especially when cutting intricate shapes and small holes. Laser cutting machines are used in an extensive range of industries for precision cutting and designing projects. A laser cutter’s beam usually has a diameter between 0.1 and 0.3 mm and a power of between 1 to 3 kW. This power needs to be adjusted depending on the material being cut and the thickness.

CNC Laser Cutting Machine utilises a high-power laser which is focused through optics and computer numerical control (CNC) to direct the beam or material. Generally, the process utilises a motion control system to follow a CNC or G-code of the pattern which is to be cut onto the sheet or material. The laser beam melts, vaporises or is blown away by a jet of gas to leave a high-quality surface finished edge. The laser beam is formed by the stimulation of lasing materials through electrical discharges or lamps inside a closed container. Then, lasing material is amplified by reflecting internally via a partial mirror until its energy is sufficient for it to escape as a stream of coherent monochromatic light. This light is then concentrated by focussing at the work area by mirrors or fibre optics which direct the beam through a lens which intensifies it. The laser beam is usually under 0.0125 inches (0.32 mm) in diameter at its narrowest point, but kerf widths as small as 0.004 inches (0.10mm) are conceivable depending on material thickness.  

The advantages of CNC Laser Cutting Machines are:

• Can create intricate designs as well as holes thinner than the gauge e.g. 2.5mm hole through 4.0mm steel.
• A cleaner cut through most materials, without nibbling marks.
• Fast: Can attain greater output and improved productivity, giving you an improved return on your investment and eventually leading to more profitability.
• Ease of use: Easy to operate as once the design software file has been imported and the laser settings adjusted.
• Value: Represent excellent value for money.
• Faster on thinner gauges (approx. up to 1.2mm) than punch presses, provided few lead-ins.
• Doesn’t depend on having a varied range of tooling, which may not allow for certain sized cut-outs.
• Versatile: Laser cutting machines can be customised for your specific industrial applications adjusted easily for a wide range of materials. 
• Precise: Can cut an extensive range of materials in intricate or complex detail to a high degree of accuracy, guaranteeing top results every time.
• Safe and Clean: Materials do not need to be clamped down and machines never expose the operator to moving parts. Laser cutting machines have a clean and efficient process, especially when used in conjunction with a CTR filtration/ventilation system.

Applications of CNC Laser Cutting Machine:

• Rapid prototyping, before producing in large scale.
• Hardware companies to create prototypes.
• Machine shops and industrial manufacturing cut large pieces of materials.
• Individual artists and makers who want to bring to life their digital designs.
• Cutting extensive range of materials.
• Research and Educational prototyping for small projects.
• Designed for clean-cutting a wide range of organic materials including wood, plywood, cloth, card, leather, laminates, plastics, TPE and many others.
