The Parameters of Laser Engraving and Cutting Machine and The Principle of Laser Engraving and Cutting Machine
The laser engraving and cutting machine is widely used in the engraving and cutting of non-metallic materials. It has the processing characteristics of material saving, smooth incision and high precision. The laser engraving and cutting machine mainly has the following parameters:
Cutting head height, laser power supply, auxiliary gas, laser pulse duty cycle, etc.
The working principle of the laser cutting machine is that the energy released when the laser beam is irradiated on the surface of the workpiece melts and evaporates the workpiece to achieve the purpose of cutting and engraving. The laser cutting machine has the characteristics of material saving, smooth incision, high precision and fast processing speed.
Laser pulse duty cycle:
that is, the percentage of time that the pulsed laser is continuously on in one cycle is proportional to the laser power. When the duty cycle is 100%, that is, it is fully turned on in one cycle, which is a continuous laser.
Cutting head height:
The laser beam is focused under the nozzle through the lens, and the power density is maximum at the focal point. Therefore, the height of the cutting head from the cutting surface not only affects the plane focusing area, but also affects the energy density at the current point
Laser power supply:
The laser power supply is divided into several parts to provide energy, and some are individually turned off when needed to reduce the power of the laser
