What is the difference between CNC plasma cutting machine and laser cutting machine

In fact, many friends are not clear about the laser cutting machine and CNC plasma cutting machine cut out of the effect in the end what is the difference, like our daily life in the sheet metal processing in the end need laser cutting machine or CNC plasma cutting machine?

Here for you to explain the difference between laser cutting machine and CNC plasma cutting machine in the end, in different environments and how to choose.

The first thing I want to tell you is how these two types of cutting machines work

1, the working principle of laser cutting machine

Laser cutting machine is the laser emitted by the laser through the optical path system focused into a high power density laser beam. The laser beam shines on the surface of the workpiece, so that the workpiece reaches the melting or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. So as to achieve the purpose of cutting.

2, the working principle of CNC plasma cutting machine

The CNC plasma cutting machine must be heated up to a certain temperature. It transmits the arc power to the workpiece. High temperature causes the workpiece to melt and blow off, forming the working state of plasma arc cutting. Then, a plasma arc is used as a heat source to melt the metal. Cutting is an arc, so there is often a certain arc when cutting fault. Because of this, when we need a right Angle cross section, CNC plasma cutting machine is no longer applicable.

Secondly, let me tell you the difference between the two kinds of cutting machine, cutting material, cost, accuracy and so on

1, cutting quality is different

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

Laser cutting machine can realize non-contact cutting with the workpiece surface, small cutting gap, high precision, small heat affected zone, cutting end face smooth without burr. CNC plasma cutting machine cutting gap is large, cutting end face rough and not smooth, cutting precision is low.

2, cutting materials are different

Laser cutting machine is suitable for cutting a wide range of materials: metal, non-metal, ceramic, glass and so on.

CNC plasma cutting machine is suitable for cutting all kinds of metal materials, mainly thick plate cutting.

3, the cost is different

In terms of consumables cost, the consumables cost of CNC plasma cutting machine is very high. For example, the entire cutting torch (nozzles, cyclone rings, electrodes, etc.) needs to be replaced within a few hours, and CNC plasma cutters consume a lot of power.

The consumable cost of laser cutting machine is very low, less wearing parts, almost no maintenance.
