Different cutting machines cut different materials.You can choose a fiber laser cutting machine to cut metal materials, a CO2 laser cutting machine to cut nonmetal materials and a mixed laser cutting machine to cut metal and nonmetal materials.
Structural steel
Cutting the material with oxygen will get better results. When using oxygen as a process gas, the cutting edge will be slightly oxidized. For the plate thickness up to 4mm, with nitrogen as the process gas and high pressure cutting. In this case, the cutting edge will not be oxidized. Plate thickness of 10mm or more lasers use special plates and oil coated the surface of the workpiece during machining can get better results.
Stainless steel
Cutting stainless steel needs: the use of oxygen, in the case of edge oxidation does not matter; nitrogen to obtain a non-oxidizing burr-free edge of, you do not need further treatment. Perforated plate surface coating film will get better results, without reducing the quality of processing.
Aluminum
Aluminum with high reflectivity and thermal conductivity and thickness of less than 6mm can be cut, depending on the alloy type and laser capability.When cut with oxygen, the cutting surface is rough and hard.When nitrogen is used, the cutting surface is smooth.Pure aluminum, because its high purity is very difficult to cut, should only be cut when a "reflection and absorption" device is installed on the system.Otherwise the reflection will destroy the optical component.Moreover, laser cutting forming technology has been widely used in the field of non-metallic materials.Can not only cut high hardness, brittle materials, such as silicon nitride, ceramics, quartz, etc.It can also cut and process flexible materials, such as cloth, paper, plastic board, rubber, etc., such as cutting clothes with laser, it can save clothing material by 10 ~ 12 percent and improve efficiency by more than 3 times.
Titanium
Titanium plates are cut using argon and nitrogen as the processing gas.Other parameters can be referred to nickel-chromium steel.It can be cut from a wide range of materials.As an accurate machining method, laser cutting can be used to cut almost all materials, including thin metal plates for two dimensional cutting or three dimensional cutting.In the field of automobile manufacturing, the cutting technology of the space curve such as the roof window of the car has been widely used.Volkswagen USES a 500W laser to cut complex body plates and various curved parts.
Copper and Brass
Both materials have a high reflectivity and a very good thermal conductivity. Brass of a thickness of 1mm or less can be cut with nitrogen; copper in a thickness of 2mm or less can be cut, the processing gas with oxygen. The only reflection-absorption device is installed on the system when to cut copper and brass. Otherwise, the reflection will damage optical components.
Plastics
1. Acrylic (also known as Plexiglas, Lucite, PMMA).
2. ABS (Acrylonitrile butadiene styrene).
3. Mylar (Polyester).
4. Delrin (POM, acetal).
5. Kapton tape (Polyimide).
6. Nylon.
7. Styrene.
8. Polypropylene (PP).
9. Polyethylene (PE).
10. PETG (Polyethylene terephthalate glycol).
11. Two-tone acrylic – top color different than core material, usually for custom instrumentation panels, signs, and plaques.
12. High density polyethylene (HDPE).
Foam
1. EPM.
2. Depron foam – often used for RC planes.
3. Gator foam – foam core gets burned and eaten away compared to the top and bottom hard shell.
Woods (MDF, plywood, balsa, birch, poplar, red oak, cherry, holly, etc.)
Cloths (leather, fabric, suede, felt, hemp, cotton)
Papers
Rubbers
Synthetic Materials
Dangerous and may cut emissions of hazardous substances to remember when cutting synthetic materials. The workability of the synthetic material: thermoplastics, thermosetting materials, and synthetic rubber.
Organics
Cutting of all organic materials.
