As far as the current technology is concerned, the main features of laser processing technology are as follows:
As far as the current technology is concerned, the main features of laser processing technology are as follows:
1. Good focusing performance, concentrated energy, small heat affected area and high machining accuracy.
2. Non-contact processing, no pollution to the workpiece, no mechanical extrusion or mechanical stress to the processing materials;
3. High degree of automation, saving labor costs;
4. No need for mold, suitable for large workpiece processing;
5. It is not limited by processing quantity and can be put into mass processing and production;
6. With computer programming, the processing is accurate, the material utilization rate is high, and the production cost is reduced;
7. Good adaptability, it can work in the atmosphere and also operate in the vacuum environment;
8. No inertia in processing, fast processing speed;
9. Wide processing range, high power density, can process almost any material.
There are four main types of factors affecting laser processing performance:
1. Laser features. Continuous output mode/pulse mode, wavelength, power, pulse frequency and duty cycle;
2. Lens parameters. The lens shape affects the focal distance, and then affects the size and depth of the laser processing area;
3. Processing material's own features, mainly including material oxidation features, melting point, specific heat capacity, etc;
4. Other factors. Such as oxygen supply rate, air flow pressure, etc.
