which kind of cutting method is suitable for you?

Lasers have been used for cutting since the 1970s. In modern industrial production, laser cutting is more widely used in sheet metal, plastic, glass, ceramic, semiconductor and textile, wood and paper and other materials processing.

In the next few years, the application of laser cutting in precision machining and micromachining will also gain substantial growth. There are a variety of cutting methods, come and see which one is right for you.

1. Laser cutting

When a focused laser beam hits a workpiece, the irradiated area heats up sharply to melt or vaporize the material. Once the laser beam penetrates the workpiece, the cutting process begins: the laser beam moves along the contour while melting the material. A jet of air is usually used to blow the melt away from the cut, leaving a narrow gap between the cut section and the plate holder that is nearly as wide as the focused laser beam.

2. Flame cutting

Oxygen cutting is a standard process used when cutting mild steel, using oxygen as the cutting gas. Oxygen is pressurized up to 6 bar and blown into the incision. There, the heated metal reacts with oxygen: it begins to burn and oxidize. The chemical reaction releases a large amount of energy (up to five times the laser energy) to assist the laser beam in cutting.

3. Melting and cutting

Fusion cutting is another standard process used when cutting metal. Can also be used to cut other fusible materials such as ceramics.

Nitrogen or argon is used as the cutting gas, and a gas pressure of 2-20 bar is blown through the incision. Argon and nitrogen are inert gases, which means they don't react with the molten metal in the cut, just blowing them away to the bottom. At the same time, the inert gas can protect the cutting edge from being oxidized by the air.
