Working principles of laser and plasma cutting machines
Working principle: The laser cutting machine focuses the laser emitted by the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, thereby achieving the purpose of cutting. The plasma cutting machine is a gas that is heated to a very high temperature and highly ionized. It transfers the arc power to the workpiece. The high temperature causes the workpiece to melt and be blown away, forming a working state of plasma arc cutting.
