How do you make a laser that can cut through steel? 10

Today's laser machines can cut steel, but the power is not very powerful and the volume is also very large.

Laser cutting is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam hits the surface of the workpiece, bringing it to its melting or boiling point, while a high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the movement of the beam relative to the workpiece, the material is finally cut to form a slit, so as to achieve the purpose of cutting.

Laser cutting processing is to replace the traditional mechanical knife with an invisible beam, with high precision, fast cutting, not limited to the limitation of cutting patterns, automatic nesting to save materials, smooth incision, low processing cost and other characteristics, will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the workpiece, and will not cause scratches to the surface of the workpiece during work; The laser cutting speed is fast, the incision is smooth and flat, and there is generally no need for subsequent processing; The cutting heat-affected zone is small, the plate deformation is small, and the cutting gap is narrow (; There is no mechanical stress on the incision, no shear burrs; High processing accuracy, good repeatability, no damage to the surface of the material; CNC programming, can process any floor plan, can cut the whole board with a large format, no need to open the mold, economical and time-saving.

Today's laser equipment can cut steel, but the power is not very powerful, and the volume is also very large, as long as you are confident, you will build a smaller and more powerful laser machine.

Some people say that with a laser diode CO2 laser tube but the distance cannot be controlled. But I thought of a very naïve way to do it, not to laugh, because the flashlight can disappear the light at a certain distance, and if you change the flashlight to a brighter one, then it will be far away, so I feel that if you calculate the ratio of the distance of the light to the intensity of the light, then you should be able to control the distance of the laser.

Haha, that's cost, and the laser for cutting steel costs more

You're so good at thinking about it, it's not practical to think about it.

If it's difficult, give a ** research to it.

Subject,You can't open this **.。

CO2 can cut non-metallic materials.

Introducing the use of metal laser cutting machines.

40mm diameter cast steel round bar, not suitable for laser cutting, laser cutting is mainly used for thinner plates, the cutting accuracy is higher, and the cost is also higher.

Plasma cutting is also less suitable for cutting solid bars.

The most suitable approach should be:

Metal band sawing machine.

The technology uses the energy released when a laser beam hits the surface of a steel plate to melt and evaporate the stainless steel. The laser source is generally a carbon dioxide laser beam, with a working age or power of 500 to 2500 watts. This level of power is lower than what many household electric heaters require, but with lenses and mirrors, laser beams can be concentrated in a small area.

The high concentration of energy enables rapid local heating, which causes the stainless steel to evaporate. In addition, because the energy is so concentrated, only a small amount of heat is transferred to the rest of the steel, causing little or no deformation. Blanks with complex shapes can be cut with great precision with lasers, and no further processing is required for the cut blanks.

Laser cutting is a sell-out.

Although almost all metal materials have a high reflectivity to infrared energy at room temperature, CO2 lasers emitting beams in the far infrared band are successfully used in laser cutting practices for many metals. The initial absorption rate of the laser beam by the metal is only, but when a focused laser beam with a power density of more than 106 W cm2 hits the metal surface, it can quickly start melting the surface in the order of microseconds. The absorption rate of most metals in the molten state rises dramatically, generally by 60% to 80%.

Nickel-based alloys, also known as super alloys, have many varieties. Most of them can be cut by oxidation melting.

Stainless steel, carbon steel, alloy steel, brass, copper, manganese steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, aluminum-zinc plate, pickled plate, copper, silver, gold, titanium and other metal plates and pipe cutting.
