美国马里兰州的宇宙飞行研究中心研究并且正在使用一种 这种加工方法可以对具有曲面的镜坯料钻削装配孔;在光通讯用电缆上钻敏感元件用孔以及对玻璃铣槽。铣削加工也是如此。进行这项工作需要使用少量的润滑剂,用于被加工的玻璃部位(见附图)。 硬质合金制钻头的切削直径通常可使用0.5～3.2毫米。将钻头在台钻上装好,最初可用轻微的力量压向工件,接着再以1800转/分进行钻削。为了及时将切屑和细尘取出,需要时常将工具从孔中抽出,进而根据需要补充滑润油。 铣削加工电可按同样方法进行,但吃刀深度每次为0.1～0.2毫米。
The Space Flight Research Center in Maryland, Maryland, has studied and is using one such method of machining to drill mounting holes for curved mirror blanks, drilling holes for sensitive components in optical communications cables, and milling glass slots. Milling is also true. This work requires the use of a small amount of lubricant for the glass part to be processed (see attached figure). Carbide drill bit cutting diameter can usually use 0.5 to 3.2 mm. The drill bit installed in the bench drill, initially with a slight force to the workpiece, and then to 1800 rev / min drilling. In order to promptly remove the chips and fine dust, it is necessary to always pull the tool out of the hole to replenish the lubricating oil as needed. Milling electric processing can be the same way, but the depth of each knife to eat 0.1 ~ 0.2 mm.
