里弗莫尔的大型光学钻石机床(LODTM)与家庭作坊的木质机床非常相似。当锋利的车刀切割旋转表面时,两者都使得一个工件旋转。但它们最终的产品却差别很大。为实验激光制造大的、不规则的反射镜时,LODTM放在最后加工,通常无需进一步抛光反射表面。它是世界上最精密的大型机床。目 Livermore’s Large Optical Diamond Machine (LODTM) is very similar to a home-based woodworking machine. When a sharp turning tool cuts a rotating surface, both cause a workpiece to rotate. But their final product is very different. When manufacturing large, irregular mirrors for experimental lasers, the LODTM is placed at the final machining, often without further polishing of the reflective surface. It is the world’s most sophisticated large machine tool. Head
