In metal manufacturing and processing, fiber laser cutting machine with its unique advantages is gradually replacing traditional cutting technology and becoming a sharp weapon in the metal processing industry. However, the configuration of the fiber laser cutting machine is different, the processing efficiency and effect will be very different. Before we buy a fiber laser machine, we must understand its six core parts and components. Let's share with you Leapion Laser Manager.
The six core components of fiber laser cutting machine include fiber laser generator, fiber laser cutting head, numerical control system, motor, frame, and lens.
The laser generator is the core "power source" of laser equipment, a device that generates a laser light source, and an expensive component in a fiber laser cutting machine. Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source.
Fiber laser is a new type of fiber laser that is newly developed in the world. It outputs high-energy-density laser beam, which is concentrated 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. Irradiate the position to realize automatic cutting.
The cutting head mainly includes cavity, focusing lens holder, focusing lens, capacitive sensor, auxiliary gas, nozzle and other parts.
The cutting head is the laser output device of the fiber laser cutting machine, which is composed of a nozzle, a focus lens and a focus tracking system. The cutting head of the laser cutting machine will follow the set cutting track, but the height of the laser cutting head needs to be adjusted and controlled according to different materials, different thicknesses, and different cutting methods.
The cutting head driving device is used to drive the cutting head to move along the Z axis according to the program, and is composed of a servo motor and a screw or gear and other transmission parts.
The CNC 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 axes, and also controls the output power of the laser. Its quality determines the stability of the operating 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 are stepper motors and servo motors. The configuration is based on the industry type and product type of the cutting object.
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.
The high-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the laser cutting machine.
Servo motor features: high motion, stable motion, high load, stable performance, smooth edges of processed products, high cutting speed. But its price is also high, and it is suitable for industries and products with high cutting requirements.
The stepping motor has high starting speed and sensitive response, which is suitable for cutting with low requirements. The price is lower. Moreover, there are many brands of stepper motors with different performances.
Fiber laser cutting machines have very high requirements for machine stability. At present, the mainstream racks on the market include gantry type, cantilever type, beam type, etc. and different racks have different functions. For example, beam-type racks are mainly used for material cutting by large manufacturers. There are also models for specific fields, such as three-dimensional fiber laser cutting, which are mainly used in the automotive industry.
Fiber laser cutting machines have many kinds of lenses, such as total reflection lenses, semi-reflection lenses, focusing lenses, laser lenses and so on. Different lenses have different functions. The quality of the lens directly affects the output power of the laser, and also affects the performance of the entire fiber laser machine.
Used to cool the laser generator. The cooling water takes away the excess heat to keep the laser generator working normally. The chiller also cools the light path mirror and focusing mirror outside the machine tool to ensure a stable beam transmission quality and effectively prevent the lens from being deformed or broken due to excessive temperature.
The gas supply system of fiber laser cutting machine mainly includes gas source, filter device and pipeline. Among them, there are two kinds of air sources: bottled air and compressed air. The gas cylinders include working medium gas cylinders and auxiliary gas cylinders for laser cutting machines, which are used to supplement the industrial gas for laser oscillation and supply auxiliary gas for the cutting head.
The machine tool part of the fiber laser cutting machine is the mechanical part that realizes the movement of the X, Y, and Z axes, including the cutting work platform. It is used to place the workpiece to be cut, and can move it accurately and accurately according to the control program, usually driven by a servo motor.
In addition to the above-mentioned six core components, the fiber laser cutting machine also needs a stable power supply, which consists of air-cooled dryers, filters, exhaust dust collectors, and slag dischargers. On the basis of selecting appropriate specifications for each component, each component cooperates with each other, and the best processing effect of the fiber laser cutting machine can be exerted.
