XT Laser-copper plate laser cutting machine
The laser cutting machine can cut a variety of metal materials, such as aluminum, copper, zinc, stainless steel, carbon steel, etc., especially suitable for cutting stainless steel materials. The laser cutting machine can achieve twice the result with half the effort, not only good cutting quality, but also fast cutting speed, but it is still difficult to cut copper plate, but if you adjust the laser cutting machine properly, you do not need to worry about the cutting quality.
For the cutting of copper products, many workers have many problems with the specific operation and parameter adjustment of metal laser cutting machine. Cutting is not only done by machines, but also requires some experience. Let’s introduce it in detail. How to cut copper material with metal laser cutting machine.
Highly reflective metal materials have always been difficult to cut by metal laser cutting machines, including copper, aluminum, gold and other metal materials. Now many metal laser cutting machine manufacturers in Shenzhen are an important issue.
When cutting highly reflective metal materials, auxiliary gas needs to be added. When the laser cutting machine cuts metal copper, the added auxiliary gas reacts with the material under high temperature conditions to improve the cutting speed. For example, combustion can be achieved by using oxygen. For laser cutting equipment, nitrogen is an auxiliary gas to improve the cutting effect. For copper materials below 1MM, metal laser cutting machine can be used for processing.
Therefore, when using the metal laser cutting machine, you need not worry about whether it can be cut. At this time, pay attention to the treatment effect, so it is better to use nitrogen as auxiliary gas. When the thickness of metal copper reaches 2MM, nitrogen cannot be used for processing. At this time, oxygen must be added to oxidize it to achieve the purpose of cutting.
Through the above explanation, everyone should know how to make copper material for metal laser cutting machine. In fact, what we pay attention to when cutting is not whether we can finish cutting the material or how much we can cut in an hour, but the cutting accuracy. How to grasp the cutting accuracy of metal laser cutting machine is the most important.
Compared with other thermal cutting methods, laser cutting is generally characterized by fast cutting speed and high quality. It can be summarized as follows.
1. Good cutting quality.
Because of the small laser spot, high energy density and fast cutting speed, laser cutting can obtain better cutting quality.
1 The laser cutting slit is thin and narrow, and both sides of the slit are parallel and perpendicular to the surface, and the dimensional accuracy of the cutting part can reach ± 0.05 mm.
2. The cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Even laser cutting can be used as the last process, and parts can be directly used without mechanical processing.
③ After the material is cut by laser, the width of the heat-affected zone is very small, and the performance of the material near the notch is almost unaffected. The workpiece deformation is small, the cutting accuracy is high, the geometric shape of the notch is good, and the cross-section shape of the notch is relatively regular rectangle. See Table 1 for laser cutting, oxyacetylene cutting and plasma cutting methods. The cutting material is 6.2mm thick low-carbon steel plate.
2. High cutting efficiency.
Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple numerical control worktables, and the whole cutting process can be fully digital controlled. In the process of operation, it is only necessary to change the NC program, which can be applied to the cutting of parts with different shapes. It can realize both two-dimensional cutting and three-dimensional cutting.
3. Fast cutting speed.
Use a laser with a power of 1200W to cut 2mm thick low-carbon steel plate, and the cutting speed can reach 600cm/min. The cutting speed of 5mm thick polypropylene resin board can reach 1200cm/min. In the process of laser cutting, the material does not need to be clamped and fixed, which not only saves the fixture, but also saves the auxiliary time of loading and unloading.
4. Non-contact cutting.
During laser cutting, there is no contact between the welding gun and the workpiece, and there is no tool wear. To process parts of different shapes, it is not necessary to change the “tool”, but only to change the output parameters of the laser. The laser cutting process has low noise, small vibration and no pollution.
5. There are many kinds of cutting materials.
Compared with oxyacetylene cutting and plasma cutting, laser cutting has many kinds of materials, including aluminum, copper, zinc, stainless steel, carbon steel and other metal materials. However, for different materials, due to their own thermophysical properties and different absorptivity of laser light, they show different laser cutting adaptability.
