英国的控制激光仪器公司研制出一种能够广泛用于各种材料的计算机数控激光雕刻装置,它的雕刻速度可达每秒钟20毫米。当把这种采用非接触、无加压工序的新装置的激光束投照在工件上,工件表面的材料便产生气化,从而雕刻出各种由计算机设定的文字、图案或标记。 British Control Laser Instruments has developed a CNC laser engraving machine that can be used in a wide variety of materials and has engraving speeds of up to 20 millimeters per second. When a laser beam is irradiated on a workpiece by a non-contact, non-pressurized new device, the material on the surface of the workpiece is vaporized to carve out a variety of computer-generated text, patterns or markings.
