The material to be cut is irradiated with a high power density laser beam, so that the material is quickly heated to the vaporization temperature, and evaporates to form a hole. As the beam moves to the material, the hole continuously forms a narrow slit to complete the cutting of the material.
A metal laser cutting machine ranges from $26,000 to over $400,000! The bottom-end metal laser cutter can handle very small, low-volume projects. But for more standard commercial applications, you need a metal laser cutter that will likely exceed the $30,000 mark. Most companies turn to a metal laser cutting service instead.
Principle: Laser cutting is to irradiate the workpiece with a focused high-power-density laser beam, so that the irradiated material rapidly melts, vaporizes, ablates or reaches the ignition point, and at the same time, the molten material is blown away by the high-speed airflow coaxial with the beam, so as to realize The workpiece is cut. Laser cutting is one of the thermal cutting methods.
Generally speaking, the quality of laser cutting can be measured by the following 6 criteria.
1. Cutting surface roughness Rz
2. Size of slag hanging on the incision
3. The verticality and slope of the cut edge u
4. Cutting edge fillet size r
5. Stripe drag amount n
6. Flatness F
