The 3 sorts of laser cutting machine

The very first, laser fusion cutting
In laser fusion cutting the workpiece soon after partial melting using the help of the molten material ejected. Because the material transfer happens only in the case from the liquid, so the process is called the laser fusion cutting. A laser beam with higher purity inert gas cutting force molten material away in the slot, and gas by itself is just not involved in cutting. The laser fusion cutting can get greater cutting speed than gasification cutting. The energy for the gasification is typically larger than the energy for the melt material. In laser fusion cutting, the laser beam is only absorbed by element. The maximum cutting speed elevated together with the boost of laser energy, with the enhance from the thickness in the plate and material melting temperature decreases nearly inverse proportion to improve. Below the situation in the laser energy need to, limiting issue is definitely the cutting seam stress and thermal conductivity of components. Laser fusion cutting material for iron and titanium metal is usually obtained without oxidation incision. Make gasification and melting but is less than the laser power density, for steel materials, inside the 104 W/cm2 ~ 105 W/cm2.
The second,Laser vaporization cutting
In the approach of laser gasification cut, material inside the slot gasification, this case will need quite high laser power. To be able to avert material to steam condensation slotted walls, the thickness of the material ought to not be larger than the diameter in the laser beam. The processing and therefore only appropriate for application inside the case of exclude melting materials has to be avoided. The processing is only applied to the field of Fe based alloy is quite tiny.The approach can’t be utilised , like wood and a few ceramics, those without having melting state and for that reason is unlikely to let material vapor condensation of components. In addition, these supplies to achieve a lot more usually thick incision. In laser vaporization cutting, the optimal beam focus depends upon the material thickness and beam top quality. Laser energy and gasification hot only have influence on the optimal focus position. Beneath the situation of your plate thickness must be, maximum cutting speed will be the material in the gasification temperature. The laser energy density is higher than 108 w/cm2, and will depend on the material, cutting depth and the beam concentrate position. Beneath the condition in the plate thickness should be, assuming that there’s sufficient of laser power, maximum cutting speed is restricted by a gas jet speed.
