With the continuous development of laser technology and maturity, laser equipment has been widely used in all walks of life, such as laser marking machine, laser welding machine, laser drilling machine and laser cutting machine, etc., especially CNC burning laser pointer cutting machine Equipment, in the rapid development of the past few years, is widely used in sheet metal, metal products, steel structures, precision machinery, auto parts, glasses, jewelry, nameplate, advertising, crafts, electronics, toys, packaging and other industries. Cutting speed, cutting quality, high precision; slit narrow, smooth cutting surface, does not damage the workpiece; not affected by the shape of the workpiece, the workpiece is not affected by the shape of the workpiece, Saving materials, more effective cost savings; simple, safe, stable performance, improve the new products. In addition to the metal material processing, Development speed, with a wide range of adaptability and flexibility.

CNC metal laser cutting equipment rack is the most important components of the laser equipment, not only the vast majority of components are installed in the rack, but also to withstand the table of gravity and acceleration and deceleration in the process of all inertial impact load. The design and development work of CNC metal high power laser pointer cutting machine frame mainly includes: determining the conditions of fast, high precision and stable operation of CNC laser cutting equipment under various working conditions and environments; determining the structure and parameters of the frame according to the functional requirements, Dynamic stiffness and thermal stability of the frame are studied, and the theoretical basis for the design of the frame is given. The design of the frame And other components of the mutual coupling between. Therefore, how to rationally arrange the metal in the design of the NC metal cutting machine frame, reduce the dead weight, improve the rigidity of the fuselage, and reduce the influence of the temperature change on the accuracy is the key consideration in the design process.

In the actual CNC metal brightest laser pointer cutting machine circuit, the analog signal and digital signals have a strong electric interference between the problem. The role of optical isolation circuit is in the case of electrical isolation, the light for the coal-mediated transmission of signals on the input and output circuit can be isolated, which can effectively suppress the system noise, eliminating the ground loop interference, a faster response, Long life, small size, impact resistance and other advantages, so that in the strong - weak interface, especially in the computer system forward and backward access to a wide range of applications.

Optocoupler has three characteristics: signal transmission to take the form of electricity - light - electricity, light-emitting part and the light-receiving part is not in contact, to avoid the output of the input side may have feedback and interference; suppression of noise interference; durable, reliable And the advantages of high speed, response time is generally within a few, high-speed optocoupler response time and some even less than 10ns. Therefore, in the NC 2000mw laser pointer cutting machine system circuit design, should pay attention to the input signal circuit and single-chip connection isolation. Here, the use of optical coupling is the most commonly used method.

In the metal processing industry, where heavy industrial manufacturing systems are important, many metal materials, regardless of the hardness, can be cut without distortion. Of course, for high reflectivity materials such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so the laser cutting machine is difficult, not even cutting.

Although the laser cutting machine technology, the obvious obvious advantages, but as a high-tech equipment, to use the laser cutting machine to achieve the desired effect of cutting, must also master the processing of technical parameters and operating procedures. Especially in the metal 1000mw laser pointer cutting machine cutting process, to select the appropriate cutting speed, otherwise it may cause several adverse cutting results, mainly in the following:

When the laser cutting speed is too fast, it will cause the following undesirable results: anti-cutting, sparking spray chaos; resulting in oblique cutting surface showing stripes, and the lower half of molten steel; resulting in the cross-section thicker, but no melting produced. On the contrary, when the laser cutting speed is too slow, it will result in: the situation caused by over-melting, cutting surface rough; slit widened, in the sharp corners of the entire melting, affecting cutting efficiency. So, in order to make laser cutting machine equipment better play its cutting function, you can cut the spark from the laser device to determine whether the appropriate feed speed: If the sparks from top to bottom spread, indicating that the cutting speed is appropriate; , It indicates that the feed rate is too fast; if the spark does not spread and less, cohesion together, then that speed is too slow.

Most organic and inorganic materials can be laser cutters. Laser cutting technology compared to other traditional cutting methods can not match the obvious advantages. Laser cutting machine not only has a narrow slit, small deformation of the main features and 5000mw laser pointer cutting speed, high efficiency, low cost, safe operation, stable performance and so on.
