英国北方灯光(Northern Neon Lights)公司用CO_2激光器切割制造广告牌用的复杂状和字母.激光器连同光线随动系统和可支持大片薄板的x-y标绘台一起工作,它能迅速更改原设计.使用激光器而不是常规的机械工具有若干优点:细小的加热点不会使材料产生畸变;无接触切割,就不需夹子,并且不会引起工具磨损;产生的切边光洁,无需进一步修整,用于镶嵌工艺足够准确. Northern Neon Lights uses CO 2 lasers to cut billboards and letters for billboarding. The laser, along with a ray-tracing system and an xy plotter that supports large sheets, can quickly change the original design. Lasers over conventional mechanical tools have several advantages: small heating spots do not distort the material; contactless cutting eliminates the need for clips and does not cause tool wear; the resulting trim is smooth and requires no further trimming for Mosaic technology is accurate enough.
