Principle And Core Components Of Fiber Laser Cutting Machine

Fiber laser cutting machine is a laser cutting machine using fiber laser as light source. It has many advantages such as excellent performance, high speed and high conversion rate. It is widely used in machining and mechanical manufacturing industry, among which the most typical are sheet metal cutting, automobile cutting and so on.

Principle of fiber laser cutting machine

Fiber laser is a new type of fiber laser developed in the world. It outputs high-energy density laser beam and gathers it on the surface of the workpiece, so that the area illuminated by the ultra-fine focus spot on the workpiece melts and gasifies instantly. The automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system, with high speed and high precision.

Core components of fiber laser cutting machine

1. Fiber laser: it is the core component of fiber laser cutting machine and the “power source” for fiber laser cutting machine to realize cutting operation. Compared with other types of lasers, fiber lasers have the advantages of higher efficiency, longer service life, less maintenance and lower cost.

2. Cutting head: the cutting head of laser cutting machine is a laser output device, which is composed of nozzle, focusing lens and focusing tracking system. The cutting head of the laser cutting machine will walk according to the set cutting path, but the height of the laser cutting head needs to be adjusted and controlled under the conditions of different materials, different thicknesses and different cutting methods.

3. Servo motor: servo motor refers to the engine that controls the operation of mechanical components in the servo system. It is an indirect speed change device of auxiliary motor. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. High quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeated positioning accuracy of laser cutting machine.

4. Chiller: chiller is the cooling device of laser cutting machine. It can quickly and efficiently cool laser, spindle and other devices. The current chillers have the advanced functions of input and output control equipment switch, cooling water flow and high and low temperature alarm, and the performance is more stable.

5. Air supply system: the air supply system of optical fiber laser cutting machine mainly includes air source, filtering device and pipeline. The gas sources include bottled gas and compressed air.

6. Host: the bed, beam, worktable and z-axis system of the laser cutting machine are collectively referred to as the host. When the laser cutting machine is cutting, the workpiece is first placed on the bed, and then the cross beam is driven by the servo motor to control the movement of z-axis. The user can adjust the parameters according to his own needs.

7. Control system: it mainly controls the machine tool to realize the movement of X, y and Z axes, and also controls the output power of the laser.

8. Regulated power supply: connected between laser, CNC machine tool and power supply system. It is mainly used to prevent interference from external power grid.
