3D Robot Fiber Laser Cutting Machine (1)
3D Robot fiber laser cutting machine includes special fiber laser cutting head, high precision capacitance tracking system, fiber laser and industrial robot system. And it is an advanced cutting equipment with multi angle and multi direction flexible cutting for metal plates of different thickness. So 3D robot laser cutting equipment is widely used in metal processing, mechanical manufacturing, automobile parts manufacturing and so on, the production of 3D workpiece processing needs.
Principle of 3D laser cutting
Produced by laser after laser by mirror transmission through aggregation mirror irradiate processing items, so that the processing of goods (surface) by strong heat and temperature increased dramatically, so that the point due to high temperature melting or vaporization rapidly, with the trajectory of the laser head so as to achieve the purpose of processing.
Characteristics of 3D laser cutting
Five axis machine tool + CO2 laser: according to the workpiece material, workpiece thickness and selection of laser power varies
Robot + fiber laser: according to the workpiece material, thickness and selection of laser power size, such as 1.5mm thick steel 200W laser, up to 5m/min

Selection of optical fiber
According to the different thickness of sheet metal, the fiber laser with different power, power cutting fiber laser is generally divided into 200W, 300W, 400W, 500W and 1000W and other specifications of different power lasers; equipped with different cooling system, to ensure the normal operation of the laser. At the same time, according to the working radius of the manipulator and the size of the workpiece to choose the appropriate length of operation of the fiber laser transmission to meet customer cutting requirements.
Requirements for auxiliary gases
The auxiliary gas used in the three dimensional fiber laser cutting machine is 99.99% oxygen, which is very helpful to the cutting accuracy, speed and cutting section effect.
