Laser Cutting Machine
CNC LASER CUTTING MACHINE
Use a high-power density laser beam to irradiate the material to be cut to quickly heat the material to vaporization temperature and evaporate to form holes. As the beam moves on the material, the holes continuously form slits with a very narrow width (such as about 0.1 mm). Finish the cutting of the material.
LASER CUTTING MACHINE FIELD
As a precise processing method, laser cutting can cut almost all materials, including two-dimensional or three-dimensional cutting of thin metal plates
In the process of processing industry operations, laser cutting is a technology that is frequently used and has a wide range of applications. In the processing field, about 73% of the processing operations require laser cutting technology to complete. Compared with traditional cutting methods, laser cutting technology has high precision, strong adaptability, low noise and good cutting quality. The waiting point is applied in a large area. At the same time, for some complex processing operations that are completed with the help of large abrasive tools, Under the application of laser cutting technology, not only does not need to apply abrasive tools, but also can ensure the quality of cutting. In the process of reducing production costs, improve production efficiency. Therefore, laser cutting technology is widely used in the fields of vehicle manufacturing, aviation and light industry.
HOW TO CHOOSE LASER CUTTING MACHINE
How to choose core components
1. Fiber laser
Fiber laser is the head accessory of fiber laser cutting machine and the core "power source" of fiber laser cutting machine. Currently, the most equipped fiber lasers on the market are: German IPG lasers and British SPI lasers. Compared with other lasers, these two fiber lasers have the advantages of higher cutting efficiency, more reliable quality assurance, longer service life, and lower maintenance costs.
2. Yaskawa Motors
Related to the cutting accuracy of fiber laser cutting machines, some manufacturers choose imported Yaskawa motors, and some smaller companies usually choose unnamed motors.
3. Control part
The control system is the dominant operating system of the fiber laser cutting machine, and its quality determines the stability of the operation performance of the fiber laser cutting machine. It mainly controls the machine tool, realizes the movement of X, Y, Z axis, and also controls the output power of the laser.
4. Cutting head
The cutting head of the laser cutting machine is a laser output device, 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.
5. Servo motor
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.
6. Laser tube
This is also the heart of the laser cutting machine. Because the price of imported laser tubes is very expensive, generally tens of thousands of yuan, most laser cutting machines use domestic laser tubes. The quality of domestic laser tubes varies greatly, and there is a big price gap. The service life of laser tubes with better quality is generally about 8000 hours.
7. Laser lens
It is related to the power of the fiber laser cutting machine. It is divided into imported lenses and domestic lenses. Domestic lenses can be divided into two types: imported materials and domestic materials. The price difference is very large, the use effect and the service life. Also very big.
