What is A Sheet Metal Laser Cutter?
Sheet metal laser cutter, also known as metal laser cutting machine, CNC fiber laser cutting machine, is a kind of CNC laser cutting machine which takes fiber laser generator as light source. The moving of laser beam is controlled by the numerical control system. The fiber laser cutting machine can be widely used for different kinds of metal materials, including Stainless steel, carbon steel, alloy steel, silicon steel, aluminum, aluminum alloy, galvanized sheet, copper, etc.
How Does A 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 workpiece material and the workpiece 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 workpiece 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 steel, oxygen must be used as an auxiliary gas to produce an exothermic chemical reaction with the molten metal to oxidize the material, while helping to blow away the slag in the slit. For metal parts with high processing accuracy, nitrogen can be used as an auxiliary gas in the industry.
What Are 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.
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.
How Much Does A Metal Laser Cutter Cost?
Once you have an idea to buy a cheap laser cutter for metal, you may wonder how to get a fair price? According to different laser sources, laser powers, laser software, driving system, control system, spare parts, other hardwares and softwares, you will get a final metal laser cutter price range from $8,000.00 to $260,000.00.
