Metal laser cutting machine processing as an advanced material cutting method, has become increasingly popular for sheet metal producers. With the continuous progress of computer control skills and optical skills, everyone on the metal laser cutting machine processing capabilities are increasingly high, this expectation is not only to be able to cut, but also to cut well and cut fast expectations.
1, laser cutting machine (main use: metal cutting, non-metal cutting) is very high precision, can be applied to different materials, different industries, for example, like kitchenware, carts, machinery and equipment, hardware, diagnosis and treatment and other manufacturing industries, especially in is some of the higher technical standards of the manufacturing industry, the laser cutting machine regulations are particularly high. It is able to carry out detailed cutting of different goods, portrayed, and then made to produce outstanding items.
2, the laser cutting machine cutting data information quickly, the traditional type of cutting machine cutting speed is slow, will waste a lot of time, the current standard laser cutting machine is able to very well avoid this problem, and, its rate to do the traditional type of cutting machine 100 times or more.
3, the laser cutting machine (the main use: metal cutting, non-metal cutting) is very high cost performance. Compared with the same industry, metal laser cutting machine has the advantage of even only 60%, which are the key reason why many manufacturers select laser cutting machine.
4, the application of laser cutting machine low cost, the company, the company's cost fee manipulation is very important, if not in the manufacturing cost fee this ring to carry out strict control, the company will increase the cost of many products, reducing profits. According to data information shows that the current standard laser cutting machine production production most can be 18 yuan per hour up and down, while the cost of the traditional type of cutting machine is 200 yuan an hour. The difference between the two is very large.
5, the laser cutting machine in the post-maintenance cost fee, low maintenance fees. Laser cutting machine main use: metal cutting, non-metal cutting; not easily destroyed, durable goods. To understand, the mechanical goods overhaul is very costly, and laser cutting machine in these areas has quite a big advantage.
Metal laser cutting machine has many distinctive advantages, among them, the variety of processed materials is one of the big advantages of metal laser cutting machine, excellent metal laser cutting machine can make our production and processing become very convenient. Below, we will introduce you to the specific advantages of metal laser cutting machine are.
(1) Because of the contactless processing, and metal laser cutting machine laser beam energy and movement speed are adjustable, so you can achieve a variety of processing.
(2) can be used to process a variety of metals, especially high hardness, high brittleness and high melting point of the material can be processed.
(3) Metal laser cutting machine laser processing process without "tool" wear, no "cutting force" on the workpiece.
(4) Laser processing of the workpiece heat-affected zone is small, the workpiece heat deformation is small, the amount of subsequent processing is small.
(5) metal laser cutting machine laser can be through a transparent medium to the workpiece in a closed container for a variety of processing.
(6) The laser is easy to guide. By focusing can be achieved in all directions of transformation, extremely easy to work with the CNC system for complex workpiece processing, therefore, metal laser cutting machine laser cutting is an extremely flexible cutting processing method.
Metal laser cutting machine for different materials to choose a different cutting gas. In addition, in the metal laser cutting machine cutting gas system inside the installation of pressure sensors to ensure that the machine tool in the gas pressure is not enough to stop working in time to avoid scrapping the cut parts. The air pressure threshold can be set by the upper screw of the pressure sensor, and the compressed air and oxygen for cutting can also be adjusted by the program-controlled proportional adjustment valve.

As we all know, laser cutting machine cutting sheet metal has incomparable advantages, it is not only high cutting accuracy, smooth cross-section without burr, whether cutting thick or thin plate can achieve good results, however, these effects are related to the laser cutting machine focus control, it is the principle of focusing and achieving better imaging effect with SLR camera. The laser cutting machine takes the laser emitted from the laser and focuses it into a high power density laser beam through the optical path system. The laser beam hits the surface of the workpiece and brings the workpiece to its melting or boiling point, while a high pressure gas coaxial to the beam blows away the molten or vaporized metal. Laser cutting machine with invisible beam instead of the traditional mechanical knife, with high precision, fast cutting, not limited to cutting pattern restrictions, automatic layout to save material, smooth kerf, low processing costs, etc., will gradually improve or replace the traditional metal cutting process equipment. Laser cutting machine recycling with the relative position of the beam and the workpiece to move, the final material to form a slit, so as to achieve the purpose of cutting.
So, what is focus control? Those who are familiar with laser cutting machine know that laser cutting machine in different materials and different thickness of the plate, in order to achieve a better cutting effect, the focus of the laser beam will be set in different places, this is what we call focus.
In the early days of laser cutting applications, the main focus is dependent on a manual mode to complete, and now with the development of laser technology, in the manual focus mode has been eliminated, automatic focus began to be achieved, such as the full range of laser cutting machine is equipped with automatic focus function. So, some people will say that are integrated in the cutting head within the optical path, by changing the height of the cutting head, but still not focusing function can be achieved? When the cutting head is raised, the focus position is high, and when the cutting head is lowered, the focus position is low. However, the truth is that we did not imagine such a simple one.
The bottom of the cutting head is the nozzle, and during the cutting work, the distance between the nozzle and the workpiece material (nozzle height) is about 0.5 to 1.5mm, which may be regarded as a fixed value, i.e. the nozzle height develops unchanged, so we can't focus by controlling the lifting and lowering of the cutting head at the same time (otherwise the company can't finish the cutting technology processing in time).
The focal length of the focusing mirror does not change, so you can not expect to focus by changing the focal length. The focal position can be changed if the focal position of the reflector is changed: the focusing lens will be lowered at the drop of the focal point, and the focusing lens will be increased at the increase of the focal point when the focusing lens is increased. mdash;mdash;This is really one way of focusing. Auto-focus is achieved using a focusing lens drive motor for moving up and down.
Another way to automatically focus is to place a variable curvature reflector (or adjustable mirror) before the beam enters the social focus mirror, and by constantly changing the curvature of the reflector, the angle of the reflected beam is changed to disperse the student, thus being able to change the main position of the corporate focus.
With automatic focus function, the machine can automatically focus to the most suitable position when processing different materials and thickness of the workpiece. This can significantly improve the processing efficiency of the laser cutting machine, thick plate perforation time will be greatly reduced.
Therefore, for laser cutting machine, the auto-focus function is an important and indispensable feature.
