IGOLDENCNC 3000W Fiber Laser Cutting Machine For Metal

Fiber Laser Cutting Machine for Metal uses invisible light beams instead of traditional mechanical knives. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting, saving materials, Our Fiber Laser Cutting Machine for Metal cuts through nearly any type of metal quickly easily with a high range of precision and accuracy, IGOLDENCNC enables more steel fabricators to add high-precision cutting capability to their operations to achieve superior cut quality and tolerance for fine featured cutting on materials from gauge to plate thickness while able to cut titanium, brass, mild steel, copper, aluminum, stainless steel, and more.

Working principle of Fiber Laser Cutting Machine:

The laser light emitted by the laser is focused by the lens to form a very small spot at the focal point. The workpiece at its focal point is irradiated by the high-power density laser spot, which will generate a local high temperature above 10000°C, which will vaporize the workpiece instantly. Cooperate with the auxiliary cutting gas to blow away the vaporized metal, and with the movement of the CNC machine tool, the purpose of cutting is achieved.

The difficulties of Fiber Laser Cutting Machine for Metal processing superalloy materials are:

1. Large work hardening tendency

For example, the hardness of the unstrengthened substrate of GH4169 is about HRC37, and the surface of the Fiber Laser Cutting Machine for Metal will produce a hardened layer of about 0.03mm. The hardness increases to about HRC47, and the degree of hardening is as high as 27%. The phenomenon of work hardening has a great influence on the life of the oxidized tip tap, and usually produces severe boundary wear.

2. Poor thermal conductivity of the material

The large amount of cutting heat generated when cutting high-temperature alloys is borne by the oxidized tip tap, and the tip of the tool bears a cutting temperature as high as 800～1000℃. Under the action of high temperature and large cutting force, it will cause the cutting edge to produce plastic deformation, adhesion and diffusion wear.

3. Large cutting force

The strength of superalloys is more than 30% higher than that of commonly used alloy steels for steam turbines. At cutting temperatures above 600°C, the strength of nickel-based superalloys is still higher than that of ordinary alloy steels. The unit cutting force of unstrengthened 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 cemented carbide (or high-speed Steel) is the main component of oxidized tip taps. The processing of high-temperature alloys with these oxidized tip taps will cause diffusion wear and abrasive wear.

Fiber Laser Cutting Machine for Metal has the incomparable flexibility and processing precision of the traditional processing method. Because it uses “contactless processing” method that does not need mold making and extra cost. Therefore, fiber laser cutting technology can effectively improve product quality, reduce production costs, reduce labor intensity, improve traditional sheet metal processing technology, and bring more benefits to manufacturers.
