Laser Metal Cutting Machines Used For

Metal laser cutting machines are widely used in industrial manufacturing of metal fabrication, school education, small businesses, home business, small shop and home shop for sheet metal fabrication, aviation, spaceflight, electronics, electrical appliances, kitchenware, auto parts, subway parts, automobile, machinery, precision components, ships, metallurgical equipment, elevator, household appliances, metal signs, metal logos, metal tags, metal profiles, metal letters, metal words, metal arts, metal crafts, metal gifts, metal tool fabrication, metal foils, adornment, advertising and other metalworking industries.

Most organic and inorganic materials can be cut by laser. In the metal fabrication industry, which occupies a heavy weight in industrial manufacturing, many metal materials, regardless of their hardness, can be cut without deformation (using the most advanced laser metal cutter to cut the thickness of industrial steel is close to 20mm). Of course, for high-reflectivity materials such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so laser cutting is difficult or even impossible to cut (some difficult materials can be cut using pulsed laser beams, due to the extremely high peak power of the pulse wave, the absorption coefficient of the material to the beam will increase sharply instantly).

Metal laser cutters are available for stainless steel, carbon steel, tool steel, galvanized steel, spring steel, alloy, iron, aluminum, copper, brass, silver, gold, titanium, nickel, manganese, cobalt, chromium, lead and other metals in hobby use, home business, small shop, and industrial manufacturing.

The following metals can be cut with metal laser cutters:

Stainless Steel: For the manufacturing industry dominated by stainless steel sheets, the laser metal cutter is an effective cutting method. When the laser cutting heat input is strictly controlled, the width of the heat affected zone of the trimming edge can be limited, thereby ensuring good stainless steel The corrosion-resistant type. Laser cut of stainless steel uses the energy released when the laser beam is irradiated to the surface of the steel plate to melt and evaporate the stainless steel. For the manufacturing industry that uses stainless steel sheets as the main component, laser cut of stainless steel is a fast and effective cutting method. The important process parameters that affect the cutting quality of stainless steel are cutting speed, laser power, air pressure and so on.

Carbon Steel: The thickness of the laser cut of carbon steel plate can reach 70mm, the slit of carbon steel cut by oxidation flux cutting mechanism can be controlled within a satisfactory width range, and the slit of thin plate can be narrowed to about 0.1mm.

Copper & Alloys: Pure copper (purple copper) is too high reflectivity, laser cut of brass (copper alloy) should use higher laser power, auxiliary gas using air or oxygen, can cut thinner plates. Pure copper and Brass has high reflectivity and very good thermal conductivity. Pure copper and brass can only be cut when a “reflective absorption” device is installed on the system, otherwise the reflection will destroy the optical components.

Aluminum & Alloys: Although laser metal cutters can be widely used in the processing of various metallic and non-metallic materials, some materials, such as copper, aluminum and their alloys, cause lasers due to some of their own characteristics (high reflectivity) cutting is not easy to process. At present, the laser cut of aluminum plates is widely used by fiber lasers. This equipment has high performance whether it is cutting aluminum or other materials.

Nickel & Alloys: They are also known as high-temperature alloys, there are many varieties, most of which can be laser oxidized and flux-cutting with good cuts.

Titanium & Alloys: Pure titanium can be well coupled with the heat energy converted by the focused laser beam. When the auxiliary gas uses oxygen, the chemical reaction is violent and the cutting speed is fast, but it is easy to form an oxide layer at the cutting edge, which may also cause over-burning. Therefore, the use of air as an auxiliary gas can ensure the cutting quality. Laser cut of titanium alloys commonly used in aircraft manufacturing is better. Titanium plates are cut with nitrogen and nitrogen as processing gases.

What Are The Advantages Of Laser Metal Cutting Machine?

You can get benefits of excellent laser beam quality, high efficiency, high speed, easy operations, low cost, low maintenance, stable running, super flexible optical effects for metal laser cutting machines. Metal laser cutters are easy to flexible industrial manufacturing requirements.

1. High precision and best stability: The use of high precision ball screw transmission mechanism, optimized CNC system control, which can meet the processing of precision parts, and the dynamic performance is stable, and it can work for a long time.

2. The cutting section is of high quality: The mechanical follow-up cutting head system is adopted, the cutting head follows the height of the plate, and the position of the cutting point is always maintained, so that the cutting seam is smooth.

3. High performance: For thin sheet metal cutting, it can replace CO2 laser cutter, CNC punching machine and shearing machine, the cost of the whole laser metal cutting machine is equivalent to 1/4 of CO2 laser cutter and 1/2 of CNC punching machine.

4. Low cost of use and high cutting speed.

What is the purpose of metal Laser Cutting Machine?

The mechanical part of the laser cutting machine has no contact with the workpiece and will not scratch the workpiece surface during operation. The laser cutting speed is fast, the incision is smooth and flat, and generally no further processing is required.

How to ensure the cutting accuracy of Sheet metal Laser Cutting Machine?

1. The laser beam condenses into a cone. When the Sheet metal Laser Cutting Machine cuts, the laser beam is tapered downward. At this time, if the thickness of the workpiece to be cut is large, the cutting accuracy will be reduced and the cutting space will be large.

2. Different cutting materials will also affect the accuracy of Sheet metal Laser Cutting Machine. In the same case, the precision of laser cutting stainless steel and aluminum will be very different. The cutting precision of stainless steel will be higher and the cutting surface will be smoother.

What is the application scope of metal Laser Cutting Machine oxidation melting cutting?

The oxidation fusion cutting effect of metal Laser Cutting Machine shows that for structural steel with the same thickness, the cutting speed obtained by this method is better than that of fusion cutting. On the other hand, the cutting quality of this method may be worse than that of melt cutting method. In practical application, it can produce wider cutting strokes, significant roughness, larger heat affected zone and lower edge quality. Laser flame cutting is not suitable for precision models and acute angles (danger of acute angle combustion). The use of pulse mode laser can limit the thermal effect, and the laser power determines the cutting speed. At a given laser power, the limiting factors are the oxygen supply and thermal conductivity of the material.

What are the specific steps of using laser cutting machine?

When the laser cutting machine is working, if it fails, it will be very dangerous. Novices must receive professional training to operate independently.

1. Observe the general safety rules of laser cutting machine. Start the laser in strict accordance with the laser starting procedure.

2. Train the operators of laser cutting machine, be familiar with the structure and performance of the equipment, and master the relevant knowledge of the operating system.

3. Wear labor protection articles as required, and wear protective glasses that meet the requirements near the laser beam.

4. Do not handle materials without knowing whether laser irradiation or heating can be used to avoid potential smoke and steam hazards.

5. When the laser cutting machine is started, the operator shall not leave the post without authorization or entrust others to be responsible. If it is really necessary to leave, the operator must stop or turn off the power switch.
