With its advantages, the fiber laser cutting machine gradually replaces the traditional cutting technology and becomes a weapon in the metal fabrication industry.
But even if they are all called fiber laser cutting machines, the processing efficiency and effects of different equipment inside will be very different. The six main parts must be checked when purchasing fiber laser machines.
1. Fiber Laser Generator
Laser generator is the core "power source" of laser equipment, just like car engine, it is also an expensive component in fiber laser cutting machine. At present, the popular brands of fiber laser generators on the market include IPG, Raycus, etc.
2. Fiber Laser Cutting Head
The cutting head is the laser output device of the fiber laser cutting machine, which consists of a nozzle, a focus lens and a focus tracking system. The cutting head of the laser cutting machine will travel according to the set cutting track, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses, and different cutting methods.
3. CNC Fiber Laser Cutting System
The control system is the dominant operating system of the fiber laser cutting machine, which mainly controls the machine tool to realize the movement of the X, Y, and Z axis, and also controls the output power of the laser. Its quality determines the stability of the operation performance of the fiber laser cutting machine. Through software control, the cutting effect can be improved.
The motor of the laser cutting machine is the core component of the motion system. The performance of the motor directly affects the effect of product processing and production efficiency. At present, the commonly used motors include stepper motors and servo motors. The configuration is based on the type of industry and product type of the cutting object.
Stepping motor: high starting speed, sensitive response, suitable for cutting with low requirements. The price is lower. There are many brands of stepper motors with different performances.
Servo motor: high movement, stable movement, high load, stable performance, smooth edges of processed products, high cutting speed, high price, suitable for industries and products with higher cutting requirements.
5. Machine Frame
Fiber laser cutting machines have very high requirements for machine stability. At present, the mainstream machine frames on the market include gantry type, cantilever type, beam type, etc. Different machine frames have different functions. For example, beam type machine frames are mainly used for material cutting of large manufacturers. There are also models for specific fields, such as three-dimensional fiber laser cutting, which is mainly used in the automotive industry.
6. Laser Lens
Laser lenses are mostly used in the entire fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as all-reflection lenses, semi-reflection lenses, focusing lenses, and so on.
The quality of the lens directly affects the output power of the laser, and also affects the performance of the whole fiber laser machine.
