The Difference between Plasma and Laser Cutting Machine

The Difference between Plasma and Laser Cutting Machine

Plasma cutting machines and laser cutting machines can often be seen in the cutting field. How much do you know about these two cutting machines? Do you know which one has higher precision? Do you know the difference between plasma and laser cutting machine? Next, let's learn the principles of the plasma and laser cutting machine.


1. Introduction to plasma cutting machines and laser cutting machines

The laser cutting machine focuses the light emitted from the laser into a high-power density beam through the optical path system. The 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 will remove the molten or vaporized metal, thereby achieving the purpose of cutting.


The CNC plasma cutting machine is a new type of thermal cutting equipment. It uses the heat of the high-temperature plasma arc to locally melt (and evaporate) the metal at the incision of the workpiece, and use the momentum of the high-speed plasma to remove the molten metal to form an incision.


2. Difference between plasma and laser cutting machine

The working gas adopted by today's plasma cutting technology has a significant impact on the cutting characteristics, cutting quality and speed of the plasma arc. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases. Plasma cutting machines are widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structures and other industries.


As the laser cutting machine can work efficiently with smooth and flat incision, there is no need to do subsequent processing. It has small cutting heat-affected zone and plate deformation, and the cutting seam is narrow. The cut has no mechanical stress and no shearing burr. With high processing accuracy and good repeatability, it will not damage the material surface. It adopts CNC programming, which can process any plan and cut the entire board with a large format. Without the need to open the mold, it is economical and time-saving.


Compared with plasma cutting machine accuracy, laser cutting machine accuracy is higher; in terms of cost, plasma cutting machines are much cheaper than laser cutting machines.


The above is the comparison of the difference between plasma and laser cutting machine. We believe that no matter it is a plasma cutting machine or a laser cutting machine, a good product can exert its best advantages as long as it is applied to the right field.
