Widely used in light industry, heavy industry and other industries, the existing traditional cutting machine, plasma cutting machine, flame cutting machine. And there are traditional cutting tools in metal cutting machines. Individual laser cutting machine is mainly metal sheet metal processing, metal cutting, metal blanking, casing, chassis cutting processing, sanitary ware, kitchenware, instrument surface board, elevator panel and so on. At present, laser cutting machine is divided into small and medium power and high power cutting machine. Small and medium power cutting machine individual under 1000W, the price is absolutely cheap, the thickness of cutting metal individual will not exceed 10 thick. And high power laser cutting machine individual in 1000W or even a few kilowatts. Cutting thickness, the price is relatively high, individual only large manufacturers such as automobile parts processing. Individual small and medium power metal cutting machine can cut 1, carbon steel plate cutting. Modern laser cutting system can cut the maximum thickness of carbon steel plate close to 20mm, the thin plate of its slit can be narrow to about 0.1mm. Laser cutting of low carbon steel, the heat affected zone is very small, and cut on flat, lubricated, good verticality. For high carbon steel, laser cutting edge quality is better than low carbon steel, but its heat affected zone is larger. The maximum cutting depth of dieneng laser metal laser machine is 10mm. 2, stainless steel cutting. Laser cutting is easier to cut stainless steel sheet. The maximum thickness of stainless steel cut by high power YAG laser cutting system can reach 4mm. We developed a small power YAG laser cutting system cutting stainless steel thickness up to 4mm. 3, alloy steel plate cutting. Most alloy steels can be laser cut with good edge quality. However, tool steel and hot die steel with high tungsten content will have corrosion and sticky slag when laser cutting. 4, aluminum and alloy plate cutting. Aluminum cutting belongs to melting cutting, to be assisted by the gas to blow away the molten cutting area, can achieve better section quality. The current maximum thickness of the cut aluminum plate is 1.5mm. 5, other metal material cutting. Copper is not suitable for laser cutting, cutting very thin. Most titanium and titanium alloys, nickel alloys can be cut by laser. Non-metallic materials. Di Neng laser CO2 laser cutting machine CO2 marking carving machine series practical cutting carving wood, paper, rubber, leather, acrylic, plastic, cloth fiber composite data, carved horn, two-color plate, lacquer copper plate. Minimum slit 0.1mm, individual metal cutting machine in cutting more than 4 thick time individual to add gas. At present, dieneng laser metal cutting machine in the air cutting thickness can reach 8 thick. The cutting thickness of carbon steel is about 8mm, with less slag hanging, and the thickest cutting can reach 10mm, which is the thickest cutting in YAG medium and small power industry. Cutting stainless steel within 6mm, carbon steel within 8mm can use air cutting effective frugal use of the old, laser cutting machine cutting consequences are also very good. For manufacturers, cost reduction is always one of the goals they pursue. With the gradual popularization of laser cutting and welding in the automobile manufacturing industry, more and more imported equipment, how to use these equipment and reduce the manufacturing cost has become a problem that manufacturers must solve. The principle of laser cutting parts is actually an oxidation reaction, in the cutting process with pressure gas to blow off iron oxide. Many CNC laser cutting machine process using high purity oxygen, because of its high purity, good effect. The price of a bottle of high purity oxygen is about 350 yuan, while the price of a bottle of ordinary oxygen is only 12 yuan, a huge difference; In addition, high purity oxygen is not easy to buy, sometimes due to traffic problems will delay the delivery time, affecting production. Whether ordinary oxygen can replace high purity oxygen is a problem we have been exploring. By adjusting various cutting parameters, we added one or more sets of filter devices outside the cutting machine and adjusted the position of the nose. After 3 months of debugging, we could finally replace high purity oxygen with ordinary oxygen to achieve the ideal effect. According to the test, each bottle of oxygen can be used for about 2.5 hours, and 3.5 bottles of oxygen are needed for one shift, about 10 bottles of oxygen are needed every day. According to the calculation of 350 yuan per bottle of high-purity oxygen, the annual normal production can save more than 1 million yuan, which greatly reduces the production cost and improves the survival of the enterprise.
