Metal is a kind of relatively difficult to cut material, because its hardness is relatively large, it is easy to make errors when cutting and it is difficult to ensure the cutting accuracy, so here we should choose the metal laser cutting machine according to the method and method of laser cutting machine processing, then How to process sheet metal? Technical engineers will analyze it in detail for everyone. Compared with general steel, the difficulties in cutting high-temperature alloys are mainly reflected in the following four aspects:

1. Large work hardening tendency. For example, the hardness of the GH4169 unreinforced substrate is about HRC37, and the surface of the metal laser cutting machine will produce a hardened layer of about 0.03mm. The hardness will increase to about HRC47, and the degree of hardening will reach 27%. The work hardening phenomenon has a great impact on the life of the oxidized tip taps, and usually causes severe boundary wear.

2. The material has poor thermal conductivity. A large amount of cutting heat generated when cutting high-temperature alloys is borne by the oxidized apex taps. The cutting edge withstands cutting temperatures of 800 to 1000 ° C. Under the action of high temperatures and large cutting forces, it will cause plastic deformation, adhesion and diffusion wear of the cutting edges. .

3. High cutting force. The strength of superalloys is more than 30% higher than the alloy steel materials commonly used in steam turbines. At cutting temperatures above 600 ° C, the strength of nickel-based superalloy materials is still higher than that of ordinary alloy steel materials. The unit cutting force of the unreinforced high-temperature alloy is above 4000N / mm2, while that of ordinary alloy steel is only 2500N / mm2.

4. The main components of nickel-based alloys are nickel and chromium, and a small amount of other elements are added: molybdenum, tantalum, niobium, tungsten, etc. It is worth noting that tantalum, niobium, tungsten, etc. are also used to make hard alloys (or high-speed Steel) is the main component of oxidized apex taps. Processing high-temperature alloys with these oxidized apex taps will cause diffusion wear and abrasive wear.

The laser industry looks promising, but as the same industry continues to increase, competitors are increasing, and the laser equipment market is oversupplied. Therefore, the development of laser equipment e-commerce has indeed helped traditional industrial enterprises change their production methods, and has developed another industrial product market in a deeper level, and has also avoided the occurrence of problems such as product backlogs and production irregularities. Because looking for large buyers through the procurement website, it is generally through large buyers to publish procurement requirements for manufacturing. This not only meets the standards of large buyers 'procurement requirements, but also saves corporate suppliers' funds to develop core technologies and improve product performance. To guarantee more profitable growth. Since its establishment, the company has always adhered to market-oriented and has continuously developed and innovated in laser applications such as laser cutting, engraving, and laser die. Now it has developed leading products laser cutting machine , laser engraving machine , laser engraving machine, laser cutting machine, laser Marking machines and other laser processing equipment are widely used in clothing, leather, advertising, craft gifts, plexiglass, electronics, electrical appliances, meters, hardware, auto parts, apparel, wood, furniture manufacturing, model manufacturing, plastics, tobacco, Packaging printing and many other fields.
