Fully automatic fiber laser cutting with different laser cutting adaptability
Fully automatic fiber laser cutting The laser cutting process has low noise, low vibration and no pollution. The types of cutting materials are metal, metal-based and non-metal-based composite materials, leather, wood and fiber. But for different materials, due to their own thermophysical properties and different absorption rates for lasers, they show different laser cutting adaptability. Using C02 laser, laser cutting performance of various materials. Disadvantages Clear light cutting is limited by laser power and equipment volume, laser cutting can only cut medium and small thickness plates and pipes, and as the thickness of the workpiece increases, the cutting speed is significantly reduced. The cost of laser cutting equipment is high and the one-time investment is large. The price of Guangdong fiber laser cutting machine laser cutting equipment is quite expensive, about 1.5 million yuan or more. With the continuous development of the current storage tank industry, more and more industries and companies have entered the storage tank industry. However, because the cost of subsequent processing is reduced, it is feasible to use this equipment in mass production. Since there is no tool processing cost, laser cutting equipment is also suitable for producing small batches of parts of various sizes that could not be processed previously. Laser cutting equipment usually uses computerized digital control technology (CNC) devices. After adopting this device, the telephone line can be used to receive cutting data from a computer-aided design (CAD) workstation. Principle Laser cutting is to use a focused high-power density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the irradiated material. At the same time, the molten material is blown away by the high-speed airflow coaxial with the beam to realize the workpiece Cut open. Laser cutting is one of the thermal cutting methods. Classification Laser cutting can be divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting and laser scribing and controlled fracture. Laser vaporization cutting uses a high-energy-density laser beam to heat the workpiece, so that the temperature rises rapidly, reaching the boiling point of the material in a very short time, and the material begins to vaporize to form vapor. The jetting speed of these vapors is very high, and at the same time as the vapor jets, cuts are formed in the material. The heat of vaporization of materials is generally very large, so a large power and power density are required for laser vaporization and cutting.
