What can a laser cutting machine do?

Laser cutting technology is widely used in the processing of metal and non-metal materials, which can greatly reduce processing time, reduce processing costs and improve workpiece quality. The modern laser has become the "sword" that people fantasize and pursue to "cut iron like mud".

Taking our company's CO2 Laser Cutting Machine as an example, the whole system consists of control system, motion system, optical system, water cooling system, smoke exhaust and blowing protection system, etc. The most advanced numerical control mode is used to realize multi-axis linkage and laser speed is not affected. It also supports DXP, PLT, CNC and other graphic formats and strengthens the interface graphic drawing processing capability; the imported servo motor and transmission guide structure with superior performance are used to achieve good motion accuracy at high speed.

Laser cutting is achieved by applying high power density energy generated by laser focusing. Under the control of the computer, the laser is discharged through pulses, thereby outputting a controlled repetitive high-frequency pulsed laser to form a beam with a certain frequency and a certain pulse width. The pulsed laser beam is transmitted and reflected through the optical path and focused on On the surface of the processed object, tiny, high-energy-density light spots are formed, and the focal spots are located near the surface to be processed, melting or vaporizing the processed material at an instant high temperature. Each high-energy laser pulse instantly sputters a small hole on the surface of the object. Under the control of the computer, the laser processing head and the material to be processed perform continuous relative motion and dot according to the pre-drawn pattern, so that the object will be processed into desired shape.

When cutting, a stream of air coaxial with the beam is ejected from the cutting head, and the melted or vaporized material is blown out from the bottom of the incision (Note: If the blown gas has a thermal reaction with the material to be cut, this reaction will provide cutting Additional energy required; the airflow also cools the cut surface, reduces the heat-affected zone and keeps the focusing mirror free of contamination). Compared with traditional sheet metal processing methods, laser cutting has high cutting quality (narrow kerf width, small heat-affected zone, smooth kerf), high cutting speed, high flexibility (any shape can be cut at will), and a wide range of materials. Adaptability, etc.
