With the development of laser cutting machine, laser engraving machine, laser marking machine use in the field it is increasingly being used for more and more material. However, different materials have different characteristics, so the use of laser cutting matters need attention are also different. To this end, small as it prepares Precautions for laser cutting of different materials.
The material will get better results when cutting with oxygen. When using oxygen as a process gas, the cutting edge will be slightly oxidized. Metal laser cutting machine for plate thickness up to 4mm can be cut with a high-pressure nitrogen as the process gas. In this case, the cutting edge is not oxidized. Plate thickness more than 10mm, the steel sheet laser cutting machine laser using special plates and processing to surface oiling can get better results.
Cutting stainless steel needs: oxygen, oxidation does not matter in the case of the edge; the use of nitrogen to give non-oxidizing burr-free edges, it is not needed to be addressed. In the plate surface coating film will get better perforation effect, without reducing processing quality.
Despite the high reflectivity and thermal conductivity, aluminum thickness less than 6mm can be cut, depending on the alloy and laser capabilities. When oxygen cutting, cutting surface rough and hard. With nitrogen, the cutting surface smooth. Because of its high purity aluminum is very difficult to cut, only in the fiber laser cutting machine system equipped with "reflection absorption" means the time to cut aluminum. Otherwise it will destroy the reflective optical components.
Titanium plate with argon and nitrogen as the process gas to cut. Other parameters can refer to the nickel-chromium steel.
Copper and brass
Both materials are highly reflective and very good thermal conductivity. Brass thickness of 1mm or less can be used for nitrogen cutting; thickness of 2mm or less copper can be cut, the gas must be processed with oxygen. Only installed on your system are "reflective absorption" means the time to cut copper and brass. Otherwise it will destroy the reflective optical components.
When cutting synthetic material cut to keep in mind the dangers and hazardous substances may be discharged. Processed synthetic materials: thermoplastics, thermosetting materials and synthetic rubber.
In all organics are cut there is a danger of fire (with nitrogen as the process gas, compressed air can also be used as a process gas). Wood, leather, cardboard and paper can be cut with a laser, the cutting edge can scorch (brown).
The increasingly popular use of laser equipment, packaging laser inkjet printer, laser marking machine leather, rubber plate laser engraving machine, laser marking and other metal has become part of people's lives, while laser cutting machine should look for cuts characteristics and needs, in order to achieve better processing.
