Fiber laser cutter is a laser cutter with fiber laser as light source.The optical fiber laser cutter consists of different components, different internal components and configurations lead to different machining effects.Therefore, it is better to know more about the components of the fiber laser cutting machine before we buy it.Different component configurations also affect their quotations.
Fiber laser is a new type of fiber laser developed in the world. The laser beam with high energy density is output and concentrated on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece melts and vaporizes instantly, and the automatic cutting is realized by moving the irradiation position of the spot mechanical system by numerical control.
Laser is the core “power source” of fiber laser cutting machine. Like the automobile engine, it is also an expensive part of the fiber laser cutting machine. At present, there are IPG, rofin, raycus and other fiber lasers on the market.
The motor of fiber laser cutting machine is the core component of motion system. The performance of motor directly affects the processing effect and production efficiency of products. At present, the commonly used motors are stepping motor and servo motor. Configure according to the industry type and product type of the cutting object.
Fast start-up speed, sensitive response, suitable for cutting with low requirements. Lower price. Stepping motor has many brands and different performance.
High movement, stable movement, high load, stable performance, smooth edge of processed products, fast cutting speed and high price. It is suitable for industries and products with high cutting requirements.
3.Fiber laser cutting head
Fiber laser cutting head is a laser output device, which consists of nozzle, focusing lens and focusing tracking system. The cutting head of the fiber laser cutting machine will walk according to the set cutting path, but the height of the laser cutting head shall be adjusted and controlled according to different materials, different thickness 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 full reflection lens, semi reflection lens, focusing lens, etc., the quality of the lens directly affects the output power of the laser, and also affects the performance of the whole fiber laser machine.
The bed, beam, worktable and z-axis system of optical fiber laser cutting machine are collectively referred to as the host. When cutting, the optical fiber laser cutting machine first puts the workpiece on the bed, and then uses the servo motor to drive the beam to control the movement of Z axis. Users can adjust parameters according to their own needs.
Fiber laser cutting machine has very high requirements for machine 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.
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, advanced cooling water flow, high and low temperature alarm and other functions, with more stable performance.
8.The laser cutting system of digital control fiber
The control system is the leading operating system of the fiber laser cutting machine. 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. 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 optical 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 during metal cutting, which plays a role in supporting combustion and protecting the cutting head.
A. 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.
B. Ventilation dust remover: suction and filter the smoke and dust generated in the processing process to make the waste gas emission meet the environmental protection standard.
C. Slag extractor: remove leftover materials and wastes generated in the processing process.
D. Stable power supply: the power supply is connected between the laser, CNC machine tool and power supply system. It mainly plays the role of preventing external power grid interference.
