1. Wide range: carbon dioxide laser almost any non metallic materials for engraving and cutting. 2. Safe and reliable: the use of non- contact processing, the material will not cause mechanical extrusion or mechanical stress. 3. Precise and detailes: processing accuracy can reach 0.02mm. 4. Saving environmental protection: light bean and spot diameter is small,generally less than 0.5mm,cutting and processing material saving,safety and health. 5.
