Compared with laser cutting, laser cutting equipment requires a larger investment

The specific dimensions of processing accuracy are determined by experiments. There are three simple methods to determine the focal position in industrial production: (1) Printing method: Move the cutting head from top to bottom and perform laser beam printing on the plastic plate, with the smallest printing diameter as the focal point. (2) Slant plate method: Use a plastic plate placed at an angle to the vertical axis to pull it horizontally and find the minimum point of the laser beam as the focal point. (3) Blue Spark Method: Remove the nozzle, blow air, and apply a pulsed laser onto the stainless steel plate, causing the cutting head to move from top to bottom until the blue spark is the focal point. For cutting machines with flying light paths, due to the divergence angle of the beam, the length of the cutting path at the near and far ends is different, and there is a certain difference in the size of the beam before focusing. The larger the diameter of the incident beam, the smaller the diameter of the focal spot. In order to reduce the changes in the focal spot size caused by changes in the beam size before focusing, manufacturers of laser cutting systems at home and abroad provide some specialized devices for users to choose from: (1) parallel light tubes. This is a commonly used method, which involves adding a parallel light tube to the output end of a CO2 laser for beam expansion processing. The expanded beam diameter increases and the divergence angle decreases, making the beam size close to the same before focusing at the near and far ends within the cutting range. (2) Add an independent moving lens lower axis on the cutting head, which is two separate parts from the Z-axis that controls the distance (standoff) between the nozzle and the material surface. When the worktable of the machine tool moves or the optical axis moves, the F-axis of the beam also moves simultaneously from the near end to the far end, so that the diameter of the focused beam spot remains consistent throughout the entire processing area. As shown in the figure.

Light steel structure [main text] Compared with laser cutting, laser cutting equipment requires a larger investment and is currently mostly used for cutting thin steel plates and some non-metallic materials. It has a faster cutting speed and higher accuracy, but laser cutting can cause arc marks and thermal effects at the cutting seam; In addition, laser cutting is not ideal for some materials, such as non-ferrous metals and alloys such as aluminum and copper, especially for cutting thicker metal plates. The cutting surface is not ideal, and it is even impossible to cut. Currently, research on high-power laser generators is aimed at solving the cutting of thick steel plates, but the costs of equipment investment, maintenance, and operation consumption are also considerable. Water cutting has low investment, low operating costs, a wide range of cutting materials, high efficiency, and easy operation and maintenance. Compared with plasma cutting, plasma cutting has obvious thermal effects, low accuracy, and the cutting surface is not easy to undergo secondary processing. Water cutting belongs to cold cutting, with no thermal deformation, good cutting surface quality, and no need for secondary processing. It is also easy to perform secondary processing if necessary. Compared with wire cutting for metal processing, wire cutting has higher accuracy but slower speed. Sometimes, other methods such as perforation and threading are required for cutting, and the cutting size is greatly limited. Water cutting can punch and cut any material with fast cutting speed and flexible processing size. For some metal parts, the punching and shearing process can be adopted, which is efficient and fast, but requires specific molds and cutting tools. Compared with this cutting method, water cutting is more flexible and can be used to cut and process workpieces of any shape at any time, especially in cases where the material is thick or hard. The punching and shearing process will be difficult or impossible to achieve, while the water cutting method is more ideal; Flame cutting is also a commonly used cutting process in the metal field, with a wide range of cutting thickness. However, compared with water cutting, its thermal effect is obvious, and the cutting surface quality and accuracy are poor. In addition, water cutting can effectively solve the cutting and processing of special materials such as high melting points, alloys, and composite materials. In the cutting and processing industries of glass, stone, ceramics, etc., the traditional method is to use diamond cutting tools for cutting, sawing, milling, etc. The cutting thickness range is very large and the speed is fast. However, for conventional thickness plates, water cutting can perform high-precision cutting and processing of arbitrary curves, with high yield, reduced production costs, and greatly improved added value of processed products..

Which is good about Dongying pile tip? Laser cutting machines in China have just emerged as mechanical processing equipment in recent years. Compared with traditional industry processing methods, their work efficiency is much higher and they have great advantages. However, our industry developed relatively late compared to foreign countries, so there is a certain gap in technology with developed countries. Many businesses are not very familiar with this trend, and there is still a lot of potential space in the market. So how can we increase the market share of domestic laser cutting machines? Firstly, the high cost of laser cutting machines has deterred many small businesses from doing so. So reducing cost is the primary issue. Due to the lack of many domestic technologies, many mechanical parts of laser cutting machines rely on foreign imports, which greatly increases the cost of production. In order to better solve this problem, we should increase the development and research of laser cutting machine parts to achieve better results. This fundamentally solves the cost problem of laser cutting machines. Then we need to know that many enterprises and manufacturers are still stuck in traditional processing methods, so we need to do sufficient promotion and popularize knowledge in this area. In this fiercely competitive environment, if we do not innovate and reform to improve production efficiency, we may be caught up and replaced by other enterprises. Therefore, vigorously promoting knowledge in this area can also increase our market share in China..

The operation of steel structure recycling shot blasting and rust removal is also very simple, but cutting 0.08mm plates is not that simple. Although the cutting above is very easy, in actual operation, due to the thin plate, the residual material is easily heated and rises during the processing, which will affect the cutting accuracy. If we rely on manual processing of the remaining materials, it will be laborious and time-consuming! Some people may think that stacking several sheets of paper together would be better! In theory, it is possible to achieve it, but in actual operation, there will be a more fatal problem, which is the degree! For the surface panel, accuracy has been achieved, but for the bottom panel, waste residue will remain on the surface, greatly reducing accuracy..

Thirdly, laser cutting machines can save plastic mold costs by cutting plastic materials. Plastic laser cutting processing does not require molds, consumes no molds, does not require mold repair, saves time for mold replacement, thereby saving processing costs and reducing manufacturing costs. It is suitable for processing large or small batch plastic products. Plastic applications are very wide, including household appliances, automobiles, mobile phones, etc PC、 Plastic processing and application are essential components in medical equipment and lighting appliances. Both are tissue boxes, but this tissue box processed using laser cutting technology has better transparency, with a transparency like crystal, making it very suitable for homes, hotels, offices, etc. It can also use laser engraving technology to carve personalized logos. Using a carbon dioxide laser engraving machine to engrave advertising crystals is undoubtedly a choice. The above two words "crystal" are carved and formed in one go using a laser engraving machine, without the need for additional polishing and grinding, making it very flexible. Laser cutting machines are used for cutting and processing plastic materials. When processing plastics, the traditional mechanical processing method is to directly apply drills and other machinery to the plastic workpiece, which causes deformation of the plastic and also forms burrs at the processing site. In order to meet production requirements, some processing is needed, which slows down the processing speed and does not meet the precision requirements. However, the use of laser cutting processing can avoid the above-mentioned drawbacks, greatly accelerate the research and development speed of new plastic products, and also accelerate the application of plastics in high-end fields. With the improvement of people's living standards, the market prospects for laser cutting processing of acrylic gifts are also getting better and better. Laser cutting processing has gained people's love for its high-speed and simple processing advantages. For example, laser cutting processing of acrylic crafts can be stored for a long time without discoloration or moisture, and can be bright and shiny..

The laser beam is irradiated onto the surface of the workpiece, causing it to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the melted or vaporized metal. The cutting robot uses an invisible beam instead of traditional mechanical knives for processing, which has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic layout saving materials, smooth cutting, and low processing costs. It will gradually improve or replace traditional metal cutting process equipment. The mechanical part of the laser blade has no contact with the workpiece and will not cause scratches on the surface of the workpiece during operation. The cutting robot has a fast speed and a smooth and flat incision, generally requiring no subsequent processing. The cutting heat affected zone is small, the plate deformation is small, the cutting seam is narrow (0.1mm~0.3mm), the incision has no mechanical stress, no shear burrs, high processing accuracy, good repeatability, and does not damage the material surface. It can be programmed with CNC to process any flat surface and can cut large entire boards without the need for molds, which is economical and time-saving. The above text is about the working principle of laser cutting robots, hoping to provide substantial help to everyone. In the process of intelligent industrial production, utilizing advanced automation equipment can create more value for enterprises and enable them to gain more development advantages in the fiercely competitive market, which is an important measure for the steady development of enterprises..

The main components consumed by a general laser cutting machine are the laser tube and laser. If the performance problems of these two components are solved, I think the service life of the laser cutting machine will naturally be longer. The combination of imported and domestic parts of the laser cutting machine also has a certain relationship. The laser cutting machine produced by advanced laser production uses all imported parts to ensure that the laser cutting machine maintains good stability and efficiency under long-term operation. In addition, the supporting chiller can cool it down to ensure the stability of the laser cutting machine..

Previously, gaskets were produced through mechanical processing.

4、 Generally speaking, the cutting width does not affect the cutting quality, but when a particularly precise contour is formed inside the component, the cutting width determines the minimum inner diameter of the contour. As the thickness of the sheet increases, the cutting width also increases. Therefore, to ensure the same high precision, regardless of the cutting width, the workpiece in the processing area of the laser cutting machine should be constant. 5、 During the machining process of metal laser cutting machine, burrs are generated by the high energy of laser beam irradiation on the surface of the workpiece, which rapidly vaporizes and evaporates the workpiece surface, and the slag on the workpiece surface is blown away by auxiliary gas. If auxiliary gas is not used, burrs will form on the cutting surface after the slag cools. Because removing burrs requires additional work, the quality of cutting can be visually judged by observing the number of burrs. (Author: Qingyuan Laser).
