With the application of laser cutting more and more widely, more and more suitable materials. But different materials have different characteristics, so in the use of durmapress laser cutting needs to pay attention to the matters are different, the following xiaobian will introduce to you.
The material can get better results when laser cutting with oxygen. When oxygen is used as the processing gas, the cutting edge is slightly oxidized. For plates up to 4mm thick, nitrogen can be used as the processing gas for high pressure cutting. In this case, the cutting edge is not oxidized. For the plate with a thickness of more than 10mm, a better effect can be obtained by using a special plate for the laser and oiling the workpiece surface during processing Durmapress laser cutting.
2, stainless steel
Cutting stainless steel needs: laser cutting using oxygen, in the case of edge oxidation does not matter; Nitrogen is used to obtain a non-oxidized, non-burring edge, and no further treatment is required. Coating oil film on the surface of the sheet can get better perforation effect without reducing the processing quality.
Despite high reflectivity and thermal conductivity, aluminum up to 6mm in thickness 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 is very difficult to cut because of its high purity and can only be cut if the system is equipped with a "reflection and absorption" device. Otherwise the reflection will destroy the optical component.
Titanium plates are cut with argon and nitrogen as processing gases. Other parameters can refer to nickel chromium steel.
5. Copper and brass
Both materials have high reflectivity and very good thermal conductivity. Laser cutting thickness of brass below 1mm can be cut with nitrogen; Copper less than 2mm in thickness can be cut, and oxygen is used for processing gas. Copper and brass can only be cut if the system is equipped with a "reflection-absorption" device. Otherwise the reflection will destroy the optical component.
6. Synthetic materials
When cutting synthetic materials, bear in mind the dangers of cutting and the possible discharge of hazardous substances. Laser cutting can be processed synthetic materials: thermoplastics, thermohardening materials and artificial rubber.
7. Organic matter
Laser cutting in all organic cutting there is a danger of fire (nitrogen as a processing gas, can also use compressed air as a processing gas). Wood, leather, cardboard and paper can be laser-cut with charred edges (brown).
In the laser cutting machine technical characteristics compared with other cutting methods, Durmapress laser cutting has the following advantages:
It is a non-contact processing, with high energy density and good controllability; High cutting speed. When cutting steel parts, cutting efficiency is increased by 8? 20 times. The heat affected zone is very small, and the workpiece is deformed. Small, the roughness of the cutting edge is very small, no need to finish machining, no need to melt after cutting, no need to deburr, narrow and constant size, can achieve strict tolerances. It can punch high-precision holes in high hardness and brittle materials. Its machining efficiency is l2? L5 times, 200 times the efficiency of mechanical drilling, and also convenient for processing, microhole group holes and special-shaped holes. Wait. Save materials. Save l5% on material? 30% can greatly reduce the production cost, high processing accuracy, stable and reliable product quality.
Durmapress laser cutting processing range
1 laser cutting processing range is very wide, can cut metal materials, such as low carbon steel, tool steel, stainless steel, aluminum and aluminum alloy, non-metallic materials, such as cardboard, wood, leather, glass, ceramics and so on.
2. Laser cutting processing can not only process a variety of materials, but also can process materials of different thickness from thin plate to thick plate.
3. Laser cutting can also process parts of different shapes, no matter the shape is simple or complex.
4. The high power density of the laser beam in the cutting process, so the material to be cut will quickly heat, melt, or even partially or completely evaporate. At the same time, a jet coaxial with the laser beam blows the material out of the slit. The quality of the cut and the edge of the cut depend not only on the design of the machine, but also on the feed of the focusing device or workpiece, or a combination of many factors.
5. Focus position depending on the material and thickness requirements, the focus can be above, below or below the material to be cut. The focus position can be adjusted automatically, and the automatic focus adjustment system ensures that the focus position is constant throughout the working range.
