laser cutting machine

Fiber laser cutting machine is a laser cutting machine that uses fiber laser as a light source. Its excellent performance, extremely high speed and high conversion rate are widely used in machining and machinery manufacturing industries. The most typical one is sheet metal cutting, Cutting in the automotive field, etc.


Fiber laser cutting machine can be used for both plane cutting and bevel cutting, and the edges are neat and smooth. It is suitable for high-precision cutting of metal plates, etc. Subway accessories, automobiles, food machinery, textile machinery, construction machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, metal external processing, kitchenware processing and other manufacturing and processing industries.


So, what is the principle of fiber laser cutting machine? What are the core components of the fiber laser cutting machine?


Analysis of the principle and core components of fiber laser cutting machine:


1. Principle of fiber laser cutting machine


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


Fiber laser cutting machine has high precision, high speed, narrow slit, minimum heat affected zone, smooth cutting surface without burrs; laser cutting head will not contact the surface of the material and will not scratch the workpiece; the narrowest slit, the heat affected zone The smallest, the local deformation of the workpiece is extremely small, and there is no mechanical deformation.


The fiber laser cutting machine has good processing flexibility, can process any graphics, and can also cut pipes and other special-shaped materials; it can perform deformation-free cutting of materials of any hardness such as steel plates, stainless steel, aluminum alloy plates, and hard alloys.


2. The core components of the fiber laser cutting machine


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


The cutting head of the laser cutting machine is a laser output device, which consists of a nozzle, a focusing lens and a focus tracking system. The cutting head of the laser cutting machine will walk according to the set cutting trajectory, but in the case of different materials, different thicknesses, and different cutting methods, the height of the laser cutting head needs to be adjusted and controlled.


Servo motor:

Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect speed change device. 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 motors can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the laser cutting machine.


Chiller:

The chiller is the cooling device of the laser cutting machine, which can quickly and efficiently cool the laser, spindle and other devices. The current chillers all contain advanced functions of input and output control equipment switches, cooling water flow, high and low temperature alarms, and their performance is more stable.


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, first place the workpiece on the bed, and then use the servo motor to drive the beam to control the movement of the Z axis. Users can adjust the parameters according to their own needs.


Air supply system:

The air supply system of the fiber laser cutting machine mainly includes air source, filter device and pipeline. Among them, there are two kinds of gas sources: bottled gas and compressed air. Control system: It mainly controls the machine tool, realizes the movement of X, Y and Z axes, and also controls the output power of the laser. Regulated power supply: Connected between lasers, CNC machine tools and power supply systems. It mainly plays the role of preventing external grid interference.
