How does laser die cutting machine work?

laser die cutting machine, laser die cutter,

CO2 laser die cutting machine’s laser is a single-wavelength, highly concentrated beam. In each wavelength of light, different materials absorb, reflect, and transmit such light in different amounts.

 

The beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine’s beam path. It may be bounced in different directions by a number of mirrors, or “beam benders”, before it is finally focused onto the plate. The focused laser beam goes through the bore of a nozzle right before it hits the plate. Also flowing through that nozzle bore is a compressed gas, such as Oxygen or Nitrogen.

 

For laser die cutting machine operations, it is important to choose a wavelength that is highly absorbable in the material you want to cut.

 

When laser die cutter energy is directed to the material's surface, the material absorbs so much energy that it quickly heats up beyond its melting temperature and reaches its degradation temperature.

 

At the degradation temperature, the material decomposes and disintegrates.Usually, smoke or smoke is released when this happens. During the die making processing ,laser die cutting machine will prodcue smoke.

 

Laser die cutting machine,there are will have many parameters that affect cut quality as well, but when all are controlled properly, laser cutting  is a stable, reliable, and very accurate cutting process.
