激光切割是一种以激光为能源的无接触加工技术。激光束经聚焦后其能量密度高达10~5～10~8瓦/厘米~2,足以汽化熔化多种工程材料。在切割黑色金属时同时吹喷氧气,氧气与金属产生氧化反应,释放大量热能促使金属进一步熔化,同时高速气流可以排除切缝中的熔渣。因此激光切割具有切割速度快、材料变形小,精度高、噪音小等优点.我厂子1978年与中国科学院长春光机所、农机部第三设计院、吉林省机械工业设计研究
Laser cutting is a non-contact laser processing technology. After the laser beam focused its energy density as high as 10 ~ 5 ~ 10 ~ 8 watts / cm ~ 2, enough to vaporize and melt a variety of engineering materials. In the cutting of black metal while blowing oxygen, oxygen and metal oxidation reaction, the release of a large amount of heat to promote further metal melting, while high-speed airflow can rule out the kerf in the kerf. Therefore, laser cutting with cutting speed, material deformation, high precision, low noise, etc ..
