Main components of fiber laser cutting machine
1、 Fiber laser
Laser is the core "power source" of fiber laser cutting machine. Just like the automobile engine, it is also an expensive part of the fiber laser cutting machine.
2、 Motor
The motor of fiber laser cutting machine is the core component of motion system. The performance of motor directly affects the effect of product processing and production efficiency. At present, stepping motor and servo motor are commonly used. Configure according to the industry type and product type of the cutting object.
A. Stepper motor:
Fast start-up speed, sensitive response, suitable for cutting with low requirements. Lower price. There are many brands of stepping motors with different performances.
B. Servo motor:
High movement, stable movement, high load, stable performance, smooth edges of processed products, fast cutting speed, high price, suitable for industries and products with high cutting requirements
3、 Fiber laser cutting head
Fiber laser cutting head is a kind of laser output device, which is composed of nozzle, focusing lens and focusing tracking system. The cutting head of the fiber laser cutting machine will walk according to the set cutting trajectory, but the height of the laser cutting head needs to be adjusted and controlled according to different materials, different thicknesses and different cutting methods.
4、 Laser lens
Laser lenses are mostly used in the whole fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as total reflection lens, semi reflection lens, focusing lens, etc. the quality of the lens directly affects the output power of the laser and the performance of the whole fiber laser machine.
5、 Host workbench
The bed, beam, workbench and z-axis system of the fiber laser cutting machine are collectively referred to as the host. When the fiber laser cutting machine is cutting, first put the workpiece on the bed, and then use the servo motor to drive the beam to control the movement of Z axis. Users can adjust parameters according to their own needs.
6、 Rack
Fiber laser cutting machine requires high stability. At present, the mainstream shelves in the market include gantry type, cantilever type, beam type, etc. different shelves have different functions. For example, the cross beam frame is mainly used for material cutting of large manufacturers. There are also models for specific fields, such as three-dimensional fiber laser cutting, which are mainly used in the automotive industry.
7、 Chiller
Chiller is the cooling device of fiber laser cutting machine, which can quickly and efficiently cool laser, spindle and other equipment. The current chillers are equipped with input and output control device switches, as well as advanced cooling water flow, high and low temperature alarm and other functions, with more stable performance.
8、 CNC fiber laser cutting system
The control system is the leading operating system of the fiber laser cutting machine, which mainly controls the machine tool to realize the movement of X, y and Z axes, 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.
9、 Air supply system
The air supply system of fiber laser cutting machine mainly includes air source, filtering device and pipeline. Among them, there are two kinds of air sources: bottled air and compressed air. The auxiliary gas blows away the slag when cutting metal, which plays a role in supporting combustion and also has a certain protective effect on the cutting head.
10、 Other parts
Air cooled dryer and filter: used to provide clean and dry air to the laser generator and beam path to keep the path and reflector working normally.
Ventilation dust remover: the smoke and dust generated in the processing process are pumped and filtered to make the exhaust emission meet the environmental protection standards.
Slag extractor: remove the leftover materials and waste materials generated in the processing process.
Stable power supply: the power supply is connected between the laser, CNC machine tool and power system. It mainly plays the role of preventing external power grid interference
