Definition of CNC Fiber Laser Cutting Machine
A CNC fiber laser cutting machine is a device used to laser cut materials in a computerized manufacturing process using G-Code commands and a highly concentrated beam of light to vaporize or melt away a given material. In practice, CNC laser cutter refers to either a cutting laser head tool (a laser head for short) that can be mounted on a CNC machine to perform laser cutting, or a CNC machine on which such a laser head has already been installed. A CNC laser cutter is a user-friendly technologically advanced device that allows reaching much higher manufacturing precision than other CNC processing tools.
Though, the best machines mostly sport lasers of powers ranging from (1500W, 2000W, 3000W, 4000W, 6000W, 8000W). Power is a determining factor of the quality of the work these machine machines can produce. To cut metal sheets like that of stainless steel, electrical steel, aluminum zinc plate, galvanized steel, titanium alloy, iron, brass, copper and other metal of varying thickness; fiber machine with power more than or equal to 1500 W should be used in order to produce distinctive cuts.
How Does It Work
Moving forward, there are many things that many buyers don’t try to learn while buying this fiber laser cutting machine; and, one of them is how this machine works. It is always good to have an extra bit of knowledge, especially of how the machine operates.
The machine operates on a laser that is emitted by a fiber laser generator. This laser is generated through an optical path that focuses the fiber laser beam on the substance in use with a very high power density. This laser beam is then illuminated on the surface of the metal to bring the metal onto its melting or boiling point. During this, the high-pressure gas links with the fiber laser beam and blows away the molten or vaporized material.
While doing all this, the laser beam moves in correspondence with the metal; thus, slitting the material and achieving the purpose of cutting.
Role of CNC Fiber Laser Cutting Machines in a Modern Workshop
Understanding where a fiber laser cutting machine fits in a modern workshop is crucial beyond just evaluating its cost. These machines, which are sizable and sophisticated, must be integrated into a well-organized environment to achieve optimal performance and quality.
