How to choose fiber laser cutting machine and plasma cutting machine?

What is the difference between plasma cutting machine and fiber laser cutting machine?

1.  Working principle:

For fiber laser cutting machine: 

The laser cutting machine focuses the laser emitted by the laser into a high power density laser beam through the optical path system, and the laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal, thereby achieving the purpose of cutting.

For plasma cutting machine:

The plasma cutting machine should be raised to a certain temperature, it will transmit the arc power to the workpiece, and the high temperature will melt the workpiece and blow it off, forming the working state of plasma arc cutting. Then, the metal is melted using a plasma arc as a heat source. The cutting is an arc, so there is often a certain arc when the cutting fails. Therefore, when the section we need is a right angle, the plasma cutter is no longer suitable.

2. Cutting effect

In terms of cutting accuracy, the plasma can reach within 1mm, and the laser can reach within 0.2mm. Therefore, the precision of the laser cutting machine is higher.

The laser cutting machine can realize non-contact cutting with the surface of the workpiece, with small cutting gap, high precision, small heat affected zone, and smooth cutting end face without burrs.

3. Cutting Material

Both plasma cutting machine and fiber laser cutting machine cut all metal ,like aluminum, brass, carbon steel, stainless steel etc. The plasma cutting machine is more suitable for heavy metal sheet, and fiber laser cutting machine can cut on sheet metal or heavy metal sheet, it is decide to the fiber laser source.( Welcome to contact us if you don't know how to choose your suitable machine)

Advantages of Laser Cutting Machines:

(1) Fast laser cutting speed: sheet metal cutting speed can reach 10m/min
(2) High cutting quality: small deformation and smooth cutting table. The laser cut groove is very small, and the laser cut surface can be directly used for welding without grinding.
(3) High cutting precision: the precision of laser cutting machine can reach 0.05mm, and the repeatability of positioning can reach 0.02mm
