航空航天工业的工件通常是由硬质金属如不锈钢、铬镍铁合金或钛制成，对于精密镗削来说都是非常坚硬的材料。让情况变得更困难的是，精密镗削往往是最后一道工序，所以任何由孔径过大引起的报废都意味着之前数小时的铣削和车螺纹都白费功夫。
LORD公司是生产昂贵和复杂的航空航天零部件的制造商，该公司的工程师为了加工发动机架上的精密镗孔而煞费苦心。每个报废零件的生产成本相当于公司整个月的预算。改进工艺显然成为当务之急。由于孔径过大而引起的报废在任何情况下都必须杜绝，LORD需要找到改进镗孔工艺可靠性的方法，于是他们向Big Kaiser和Blaser Swisslube寻求帮助。详情请见《消除精密镗削的废品》。
在航空航天工业中，极端的操作环境将材料和零件推向设计能力的边缘，业界公司不断寻求经济上可行的方式来保持和提高性能，其中解决腐蚀和磨损是非常重要的问题。由于使用了具有致癌性的六价铬盐，硬铬涂层（HCP）受到更加严格的法规限制，其替代品例如HVOF涂层等也有着各自的局限之处。
低温化学气相沉积（CVD）涂层则是一种实用的能显著提高飞机零件寿命的解决方案，并且在技术上和商业上可行。它将高硬度、韧性和延展性结合起来，能提高耐磨性、耐侵蚀性、耐冲击性以及承受零件变形而不受影响。请见《提高易磨损、腐蚀性航空环境中的零件寿命》一文。
