What is the difference between a Laser cutting machine and a plasma cutting machine?

Diference 1: The difference in cutting thickness
The plasma cutting machine is a kind of thermal cutting equipment, which is more suitable for more than 6mm thickness and with low
precision requirement. In theory, the maximum thickness of a plasma laser cutting machine can reach hundreds of mm, but the optimal cutting range is about 80mm. Disadvantages of plasma cutting: It is not suitable for cutting below 3mm metal sheets, the slit is wide and the precision is poor, the cutting surface with poor perpendicular when cutting 5mm or more than 5mm thickness plate.

Diference 2: The difference in cutting quality
The cutting principle of the plasma cutting machine is to use high temperature plasma arc heat to melt the metal at the cutting part of the workpiece, and simultaneously blow away the molten metal with a high-speed air flow to form a narrow slit; the plasma cutting machine can cutting stainless steel, iron, aluminum, various metal materials.
