Fiber laser marking machine can process a variety of metal materials, especially for high hardness, high melting point, brittle material marking more advantages. Non-contact processing, no damage to the product, no tool wear, marking quality is good. The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small. High processing efficiency, using computer control, easy to realize automation. Adopt the integrated structure, can be equipped with automatic focusing system, the total operation process humanized.
