As a subtractive surface treatment method, laser engraving forms patterns or text by making use of a laser beam to remove or alter the material’s surface.
Advantages of engraving
High precision
Take the most used fiber laser engraving machine for example, it can engrave a thin line of 0.01mm(about 1/5 of human hair) at ±0.003mm accuracy. This far exceeds the precision achievable by hand.
Long durability
The marks made by laser engraving are permanent and highly durable.
Quick operation
The engraving laser can move precisely at a high speed of 500–1,000 mm/s, allowing it to cover and engrave an area of 100 cm² in a minute, which is about 1/6 of an A4 paper.
Highly automated
Program settings and computer control enable laser engraving to achieve highly automated processes and eliminate errors.
Environmental friendly
Laser engraving can reduce errors or waste caused by manual engraving, thereby being more environmentally friendly.
