1. Fiber laser
The laser is the most important "power source" of the laser equipment. Just like the automobile engine, it is also the most expensive part of the fiber laser cutting machine.At present, the common fiber laser brands on the market include Germany IPG, ROFIN, Britain SPI and so on.
2. Cutting head
The cutting head is the laser output device of optical fiber laser cutting machine, which consists of nozzle, focusing lens and focusing tracking system.The cutting head of laser cutting machine will walk according to the set cutting track, but the height of laser cutting head needs to be adjusted and controlled under the circumstances of different materials, different thickness and different cutting methods.
3. Numerical control system
The control system is the dominant operating system of the optical fiber laser cutting machine. It mainly controls the machine to realize the movement of X, Y and Z axes, and also controls the output power of the laser.Its quality determines the operation performance stability of optical fiber laser cutting machine, and the accuracy and cutting effect can be effectively improved through the precise control of software.
Laser cutting machine motor is the core part of the motion system, the performance of the motor directly affects the product processing effect and production efficiency, currently commonly used motor including stepping motor, servo motor two categories, according to the type of industry and product type of processing objects, the most suitable motor configuration.
(1)Stepper motor :fast starting speed, sensitive response, suitable for carving and cutting.
(2)Servo motor : fast speed, stable motion, high load, stable performance;Smooth edge of processed products, fast cutting speed, suitable for high processing requirements of the industry and products.
5, machine tool
Fiber optic laser cutting machine has very high requirement for the stability of the machine tool. High precision and high stability of the machine tool is conducive to improve the accuracy of laser cutting.At present, the mainstream machine tools on the market are gantry type, cantilever type, beam type;Different machine tools have different functions.
6. Laser lenses
In the whole optical fiber laser cutting equipment, the most used is the laser lens. Many optical devices contain laser lens. Different lenses have different effects, such as full mirror lens, half mirror lens, focusing lens and so on.The quality of the lens directly affects the output power of the laser, as well as the performance of the whole machine.
