The differences between the two machines are mainly analyzed from the working principle, cutting quality, cutting materials and use cost.
1.How it works
Plasma cutting machine
The plasma cutting machine uses a highly ionized gas heated to a very high temperature as a heat source, which melts the metal and blows it away to form a plasma arc cutting process.
Fiber laser cutting machine
The fiber laser cutting machine uses a high-power density laser beam to scan the surface of the material, heat the material to several thousand to tens of thousands of degrees Celsius in a short time, melt or vaporize the material, and then use high-pressure gas to blow the melted or vaporized material away from the slit, thereby achieving the purpose of cutting the material.
2.Cut Quality and Materials
In terms of cutting accuracy, plasma can reach within 1mm, and laser can reach within 0.2mm, so the laser cutting machine has higher precision. The laser cutting machine can achieve non-contact cutting with the surface of the workpiece, with a small cutting gap, high precision, a small heat-affected zone, and a smooth cut end surface without burrs. However, the cutting gap of the plasma cutting machine is slightly larger, the cut end surface is rough and not smooth, and the cutting accuracy is low..
Both cutting machines are used to cut metal materials. Plasma cutting machines are mainly used for thick plate cutting, while fiber laser cutting machines are mainly used for thin plate metal cutting.
3.Cost
The purchase price of a plasma cutting machine is much cheaper than that of a laser cutting machine, because a laser cutting machine is made up of many precision parts and the cost of mechanical parts is higher. However, in terms of consumables cost, the consumables cost of a plasma cutting machine is very high. For example, the entire cutting torch (nozzle, swirl ring, electrode, etc.) needs to be replaced within a few hours. Plasma cutting machines consume a lot of power, but laser cutting machines have very low consumables cost, fewer wearing parts, and almost no maintenance is required.
