Advantages of Laser
Laser processing in the application of food machinery has the following advantages: laser cutting is a non-contact processing, which is very clean, suitable for food machinery production; laser cutting of the slot is generally 0.10 ~ 0.20mm; 1w laser pointer Cutting cutting surface without burr, can cut a variety of thickness of the plate, and the truncated surface is very smooth, no secondary processing to create high-grade food machinery; speed, and effectively improve the efficiency of food machinery production; large pieces of mold manufacturing costs are high, Laser cutting without any mold manufacturing, and can completely avoid the formation of the material when the collapse of the pile, a significant reduction in production costs and improve the quality of food machinery. Once the product drawings are formed, you can immediately laser processing, in the shortest possible time to get new products in kind, effectively promote the upgrading of food machinery. Laser processing using computer programming, can be different shapes of products for the material cut, to maximize the utilization of materials, reduce the cost of food machinery production.
Laser cutting machine in the cutting process, the auxiliary gas is essential! Which we often use oxygen and nitrogen, of course, the higher the purity of the gas, the quality of cutting will be better. There are many customers want to save the cost of using air cutting, but the cutting process to protect the 3000mw green laser lens is always water mist, cutting quality is poor. The use of gas to blow away the metal slag while protecting the lens, to avoid slag attached to the lens, affecting the quality of cutting. Can effectively achieve the cutting surface smooth, no burrs without the effect of hanging dregs, are fine cut off. Can react with the material, increase the cutting speed, for example, the use of oxygen can achieve the effect of combustion.
So, in order to achieve a better cutting effect, the requirements of the auxiliary gas is relatively high! Although the air can be used as auxiliary gas, but because the air contains water and oil, if not treated, will cause the lens pollution, cutting head instability, so that the cutting effect and quality is not compliance. Therefore, in the use of air cutting, the need for fiber green astronomy laser cutting machine equipped with cold and dry machine, so that a very good solution to this problem. The cold and dry machine can be forced to cool the compressed air below the required dew point temperature, which will contain a large number of water vapor, oil mist condensed into droplets, separated by gas and liquid, drained from the drainage machine, the compressed air drying.
For the large-length metal pipe full-stroke automatic laser cutting cutting process requirements, in the mechanical structure using a unique dual-drive pneumatic chuck rotation mechanism (drive shaft W, driven shaft W1), the left side of the active shaft W-axis pneumatic chuck Rotating mechanism is fixed, the pipe clamped, through the machine X, Y, W movement of the pipe cutting, the right side of the driven shaft W1 pneumatic chuck rotation mechanism can work along the table along the workpiece axial movement, can be large Length of metal pipe full range of automatic laser cutting cutting.
CNC laser tube cutting due to high cutting efficiency, programming nesting more complex, if used improperly, it will cause waste of pipe and cutting efficiency is low. Through the professional tube cutting nesting software on the computer in advance to draw, nesting, cutting sub-programming, generate NC cutting procedures, and then large-length metal pipe full automatic burning laser pointer cutting cutting. Professional pipe material nesting software is to achieve CNC tube cutting machine large quantities, high efficiency, high-quality cutting production of the basis and prerequisites.
As the pipe cutting (especially for small diameter square pipe), the slag attached to the tube wall, cutting most of the heat generated by the workpiece absorption, cutting density is large, often lead to overheating pipe, corner and square tube four A corner burned, seriously affecting the quality of incision, or even impossible to cut. Such a problem can be used: laser cutting headband height sensing servo system to ensure that the cutting process, the cutting nozzle and the workpiece table surface height remains unchanged (focus unchanged), so that the cutting effect does not change with the workpiece surface And affected; increase the pressure of oxygen (6-8Mpa); through the software to improve the sharp angle synthesis speed.
Laser cutting technology is in the process of rapid development and continuous improvement, with the computer technology, mechanical structure, cutting technology and optimization algorithms continue to update and develop, CNC high power laser pointer cutting technology will be more prominent to show its intelligent, fast and optimized Cutting technology and skills for the laser tube cutting machine efficient cutting, high-quality cutting, as well as saving pipe and energy consumption, to provide technical assurance.
