CNC Laser Cutting also referred to as Computer Numerical Control laser cutting is the very latest in technology that makes use of computer capabilities along with high density light energy to make very accurate cuts. The metal piece cut by the laser is vaporized thus ensuring that the finished piece has very minimal distortion, if any. Today, metallic sheets made of stainless steel, aluminum alloy, titanium, or for that matter any other metal are normally cut by using a CNC Laser cutter. This machine is generally used whenever there is a need for creating a thicker metal or for making prototypes in certain projects.
Need for these machines
Well, CNC Laser Cutting offers certain advantages that are lacking in other cutting machines. Unlike other technologies, you can start production immediately. This is because you do not have to wait for a long time to set up these machines. Further, using these machines help in reducing the set up time as well as the engineering time. Likewise, you can do away with hard tooling. The use of CNC technology helps in reducing the amount of work that needs to be done thus enabling you to start working on a project the moment you receive a work order.
How does it Work
Well, put simply, a CNC Laser Cutter uses laser technology to cut materials. Laser cutting is not meant for domestic purposes and is designed for production units. These machines have to be used in a controlled environment and that too by a trained and skilled professional. In CNC laser cutting, a computer aided high density light energy is directed on a specified metal. It is the computer that defines in what specifications the sheet metal should be cut. When the laser comes in contact with the metal, it simply melts or burns or vaporizes the area to be cut. This results in a high quality finished edge that is perfect and as per the desired specifications. CNC laser cutting is used to cut structural and piping materials along with flat sheet metals.
Types of Laser
CNC laser cutting involves using different types of laser. Let us understand what their uses are. For instance the CO2 laser is ideal for boring, engraving and cutting a variety of materials, including metals. Likewise, you have the Nd (Neodymium) laser which is ideally used when there is a need for low repetition and high energy. Similarly, Nd-YAG or Neodymium Yttrium Aluminum Garnet laser is quite identical to Nd laser and is used in boring and engraving applications where there is need for very high power. Further, these three types of laser are also used in cutting and welding too.
Finally, CNC Machined Parts are produced through a process that involves the use of computers and other precision driven tooling systems.
