The cell phone jammer performs well in the practical use

 The cell phone jammer performs well in the practical use.
In the three-dimensional laser cutting, ask for a higher beam quality laser power density and laser beam mode or as close as possible to achieve TEM00 fundamental mode, the laser beam should have a good rotational symmetry, and by linearly polarized laser output light, and then by an external circular polarized light into the optical path, cutting in different directions in order to ensure consistency of cutting conditions. Laser output should have both continuous and pulsed laser laser output can be quickly converted between the two functions. Rigid three-dimensional laser cutting machine tools, processing speed, high precision, but the laser head close to the processing capacity of the region is poor, and expensive; laser cutting robot although the high flexibility of the laser head close to the processing capacity of the region to enhance , and can use the optical fiber transmission YAG laser processing, but processing speed and processing accuracy is less than the three-dimensional laser cutting machine. Therefore, the body panels during the three-dimensional laser cutting, precision cutting and cutting to improve the quality of the world's major car companies in general three-dimensional laser cutting machine. The cell phone jammer company should try the best to prevent the destroy of cell phone jammer in the shipping process from happening.
Cutting head to achieve the three-dimensional curve motion, three-dimensional laser cutting machine is at least five-axis, that is, the linear motion of three mutually perpendicular axes and two rotary axes. Body panels during the three-dimensional laser cutting, laser head and there is no direct contact between the workpiece, cutting in order to ensure the quality requirements of the laser beam focus position to be always the same, that is, the lower surface of the cutting head nozzle surface and space between the panels The distance value. To achieve this requirement, you need to place the nozzle in the cutting head design a sensor detection device (tracking device) at any time to adjust the amount of defocus control, so it will be more than a single linear motion axis (servo axes), so Three-dimensional laser cutting machine is generally six Five Axis. Robot in the 20th century one of the greatest inventions of mankind, it is melting modern mechanics, automatic control, computer science and engineering, artificial intelligence, microelectronics, optics, communications technology, bionic technology, sociology and other disciplines and technologies in one, highly integrated. In a way, it is a measure of a country's level of scientific development, an important signal of a country's comprehensive national strength is an important manifestation. Therefore, the world striving to develop their own robot industry, the robot technology will become the core technology of this century, one of the world.
