What Is A CNC metal laser cutting machine?
CNC metal laser cutting machine is a kind of CNC laser cutting machine for sheet metals, metal plates, metal profiles, metal tubes and metal pipes, which is the best metal cutting solution for metal fabricator.
CNC metal laser cutting machines are available for 2D metal cutting projects of stainless steel, galvanized steel, carbon steel, mild steel, cold rolled steel, hot rolled steel, copper, brass, alloy, iron, silver, gold, titanium, aluminum, bronze.
There are 8 main components join CNC fiber metal laser cutting machine:
1. machine frame, 2. laser power supply, 3. laser generator, 4.reflector path, 5.laser cutting head, 6.water chiller, 7.control panel 8. CNC (Computer Numerical Control) system.
How Does A CNC Metal Laser Cutting Machine Work?
The energy of the laser is concentrated into a high-density beam in the form of light. The laser beam is transmitted to the work surface, generating enough heat to melt the material, and the high-pressure gas coaxial with the beam directly removes the fused metal to achieve the purpose of metal cutting. This shows that laser metal cutting is essentially different from CNC machining. A laser metal cutting machine uses the laser beam emitted from the laser generator to focus on the laser beam irradiation condition of high power density through the external circuit system. The laser heat is absorbed by the work piece material and the work piece temperature rises sharply. After reaching the boiling point, the material begins to vaporize and form holes, as the relative position of the beam and the work piece moves, will eventually form a slit in the material. The technological parameters (cutting speed, laser power, gas pressure, etc.) and movement trajectory during slitting are controlled by the CNC system, and the slag at the slit is blown off by the auxiliary gas with a certain pressure. During laser-cut metal, auxiliary gas suitable for the material to be cut is also added. When cutting mild steel, you need to use oxygen as auxiliary gas to help the cutting. When cutting stainless steel and other metal,you need to use Nitrogen as auxiliary gas to help the cutting.
What Are Metal Laser Cutters Used For?
Laser metal 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, metal furniture,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.
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.
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. The cutting thickness of different laser powers is different, higher power laser metal cutting machine can cut thicker metals. At present, XDLASER 15000W laser metal cutting machine has been mass-produced, and the thickness of different metals that can be cut: the carbon steel cutting thickness up to 50mm; the stainless steel cutting thickness up to 20mm; the brass cutting thickness up to 15mm; the aluminum cutting thickness up to 18mm.
How Many Types Of CNC Metal Laser Cutting Machines?
Metal laser cutter is also known as laser metal cutter, laser metal cutting machine, metal laser cutting machine, laser metal cutter machine, laser metal cutting tool, laser metal cutting table, laser metal cutting system, laser metal cutting equipment. Metal laser cutters are divided into fiber laser cutters for metal, CO2 laser cutters for metal according to laser source. Laser metal cutters are divided into sheet metal laser cutting machine, flatbed laser metal cutting machine, laser tube cutting machine, and combo laser metal cutting machines for both sheet metals and metal pipes.
