Analysis of Precision Laser Cutting Advantages and Processing Technology

Advantages of precision laser cutting:

Abroad, since the invention of the ruby laser by Bell Labs in 1960, lasers have gradually been used in audio-visual equipment, distance measurement, medical instruments, processing and other fields. As for laser processing, although the laser transmitter is very expensive (hundreds of thousands to millions), compared with traditional processing methods, laser processing technology accounts for more than 50% of the processing industry in the United States, Italy, Germany and other countries.

Precision laser cutting technology:

The laser beam can focus on small sizes and is particularly suitable for precision processing. Laser processing technology can be divided into three levels from the perspective of processing material size and precision:

(1) Large-scale laser processing technology for large-scale laser processing of materials with a thickness of tens of millimeters as the main object, and its processing precision is generally millimeters or sub-millimeters;

(2) Precision laser cutting technology, the main processing object is thin plates (0.1~1.0mm), and its processing precision is generally at the 10 micron level;

(3) Laser micro-processing technology, with various thin films with a thickness of less than 100渭m as the main processing object, and its processing precision is generally less than 10 microns or even sub-microns.

Precision in the mechanical industry generally refers to small surface roughness and small range of various tolerances (including position, shape, size, etc.). The precision here refers to the small gap in the processing area, that is, the small size limit that can be achieved by processing.

Among the above three types of laser processing, the laser processing technology of large parts is becoming increasingly mature and the degree of industrialization is very high; laser micro-processing technologies such as laser fine-tuning, laser precision etching, and laser direct writing technology are also widely used in industry.

The precision laser cutting process steps are as follows:

1. Drawing (draw CAD drawings as needed)

2. Layout (select the appropriate material size and discharge the required materials according to the nesting)

3. Layout generates CNC and then exports it to the laser cutting machine.

4. Cutting laser cutting machine.

The processing process is basically like this, but there are many things to pay attention to in each step.
