Laser cutting

• 1. Flame cutting
• Flame cutting is a standard process used when cutting mild steel, it uses oxygen as the cutting gas. Pressuring the oxygen up to 6 bar and blow it into the incision, then the heated metal reacts with oxygen and starts combustion and oxidation. The chemical reaction releases large energy to assist the laser cutting that is the flame cutting.
• 2. Fusion cutting
• Fusion cutting is another standard process of cutting metal. It also can be used to cut other fusible materials such as ceramics. It uses nitrogen or argon as the cutting gas, and the gas with a pressure of 2-20 bar blows through the incision. Argon and nitrogen are inert gases, which means they do not react with the molten metal, just blowing the extra material. At the same time, the inert gas can protect the cutting edge from being oxidized by air.
• 3. Vaporization cutting
• During the laser vaporization cutting process, a high-energy-density laser is used to heat the material, causing the temperature to reach the boiling point of the material rapidly, and the material begins to form steam. These vapors are ejected at a very high speed and form an incision. The vaporization heat of the material is generally very large, so vaporization cutting requires large power and power density. Vaporization cutting is always used to cut thin metal materials and non-metal materials such as paper, cloth, wood, plastic film, plastic rubber, etc.

The advantages of sheet metal laser cutting:

• 1. Laser cutting with high flexibility, fast speed, high production efficiency, and short production cycle. Whether it is simple or complex parts, laser cutting can be used to achieve rapid forming and cutting at one time.
• 2. Narrow cutting slit, good cutting quality, high degree of automation, easy operation and low labor intensity
• 3. Automatic cutting and nesting can be realized, which improves material utilization, no tool wear, and good material adaptability.
• 4. It is easy to operate, reduces labor intensity for workers. And with low production costs to get good economic benefits.
• 5. There is no pollution during the processing and no harm to the human body.
