Fiber Laser Cutting VS Plasma Cutting

Fiber Laser Cutting VS Plasma Cutting

KNOPPO laser have been 17 years experience for CNC metal cutting machine , most plasma cutting customer begin to choose fiber laser cutting machine now . Knoppo fiber laser machine help customer get more and more orders because of good cutting surface and precision .

As the analysis of consumption of China’s steel industry, the main application industry of steel are construction, machinery, automobiles, energy, followed by shipbuilding and home appliances. Most of the sheets used in these industries are medium and thick plates. Plasma cutting is often used in traditional medium and thick plate processing.

However, there are some problems. For example, plasma can not cut small holes, poor dimensional accuracy, large thermal influence, can not cut small parts, wide slit, waste material, and pollution etc.

Fiber laser cutting can make up for the disadvantages of plasma cutting , especially the development of high power fiber laser cutting , which solves the limitation of thick plate cutting in the past of years , and is favored by more and more sheet metal processing users.

At present, many industries such as heavy industry are discussing and experimenting to replace plasma cutting machine with fiber laser cutting machine . Compared with plasma cutting , fiber lasers have many advantages, including: high efficiency, better cutting effect and economic benefit.

Because fiber laser beam can be focused into a very small spot, the laser slit is smaller for the same size plate, the slit of plasma cutting is larger. Compared with plasma cutting, fiber laser cutting can save 6-9% of materials.

As far as cutting precision is concerned, plasma is within 1mm, and fiber laser can be within 0.2mm. The cutting principle of the plasma cutting machine is to use the heat of high temperature plasma arc to melt the metal at the cut of the workpiece, but the cutting surface is rough and low accuracy.

Fiber laser cutting has not contact with the surface of the workpiece, with small slits, high precision, smooth end faces, no burns, which can meet the high precision requirements of aerospace, power equipment, petroleum equipment, automobile manufacturing, and more industries.

Fiber laser cutting is flexible, and it can cut any complex graphics, cut pipes, cut angles , cut channels. Besides, fiber laser cutting is a non-contact cutting, ensure that the workpieces is not scratched, the cutting edge is less affected by heat, no thermal deformation, and the whole process is environment friendly .

Plasma cutting will cause large or small damage for the workpieces. If there is a problem with the cutting nozzle during cutting process, it will cause obvious defects to the plate, and the smoke and dust will pollute the environment .
