In hot and humid places, rust of metal materials such as iron plate and carbon steel is a very normal phenomenon. Can you cut the rusty steel plate directly with a laser cutter? The answer, of course, is: No.
We all know that laser cutting machine is a kind of clay product, but the laser of laser cutting machine can't do anything to rusty surface. Because the laser itself can not be a light source, only through the absorption of the surface of the thin plate workpiece can heat be generated. For rust free materials and rusty materials, laser absorption is very different, and the cutting effect is also different.
For example, the cutting condition of the uniform corrosion plate is better than that of the uneven corrosion plate. Because the absorption laser of uniform corrosion plate is also uniform, it can be cut well. For the material with uneven surface corrosion, the surface condition of the material should be uniform before cutting. Of course, if conditions permit, it is recommended to use a grinder to remove rust first.
For thick rusted plates, if the rusted plates are directly cut by laser cutting machine, it is easy to cause the phenomenon of anti-seepage cutting, poor cutting quality, and even slag splashing, which may lead to the damage of protective lenses, even focus lenses, resulting in the bursting of ceramic body. Therefore, if cutting the material with thick rust, the rust must be removed before cutting.
Accurate positioning, no damage to materials: laser cleaning machine can clean aluminum, carbon, stainless steel, carbon fiber reinforced polymer or coating materials and other very sensitive material surfaces, no damage to materials. Or the laser acts on the surface of the material to make it rough, so as to increase the bond strength.
Since China first domestically-made aircraft carrier Shandong ship was delivered to the Navy, foreign market research institutions have issued a report predicting that in the next few years, China’s shipbuilding industry will still have a lot of room for development, and technological innovatio
he temperature of the working environment of the laser should be controlled at about 22°C, the low-temperature water temperature of the chiller should be set at 20-24°C, and the temperature of the high-temperature water should be set at 28-30°C.
The 100-watt unit is pretty useful at manufacturing centers, but it's also a favorite of hobbyists. You can use it to cut through a lot of materials for your home-based laser engraving company.
CNC stands for ‘Computer Numerical Control’. That means machine has the potential to change the design patterns into numbers, created by Computer Assisted Design Software (CAD) (CAD). Ses translated numbers monitor the motions of the cutter. Machine guides the cutting and engraving of items in this manner.
Where large brand names were once a symbol of dominance, customers are now turning towards small-batch craft goods. People are tired of mass-produced uniformity and are searching for goods that reflect their creativity.
A lot of laser cutting machine manufacturers are focused on price competition in the purchasing of laser cutting machines, in the face of laser market cohabitation, which is currently a bit chaotic, particularly at present in China. Let the consumer get more and more puzzled, then how much does
Aser Cutting is the process by which the laser beam is used to vaporize, melt or otherwise eventually extract the material. Computer Numerical Control (CNC) Laser Cutting typically uses optics, an assist gas, and a guidance device to aim and concentrate the laser beam on the workpiece. Many of th
Making the CutLaser cutting is a fantastic technique that is commonly used today to render accurate cuts to flat materials. It slices, tags, or engraves objects such as wood, acrylic, and metal by emitting a directed light beam from a movable head.This subtractive machining technique is suitable
The arrival of summer solar term in May means that summer is coming and the temperature is obviously rising. At this time, thunderstorms increase and humidity is heavy. Frequent rainfall and humid environment can easily lead to condensation inside the laser, which will reduce the performance of
In the metal processing industry, fiber metal laser cutting machines are increasingly becoming popular.And we believe many investors in laser machines have an interest in the topic.That is the mainstream application field of fiber laser cutting machines for industries.So that they can better grow
