当老的机床停止服役时,人们一般首先想到的是购买一台新的设备,而忽视了现代化革新潜力。例如下面所述的一台改造后的加工透平叶片的专用铣床,它表明机床的现代化改造是可行的,并且能够取得效益。 透平叶片的铣削是属于较复杂工序,它是被夹紧在专用夹具中由专业技工利用现有技术来完成。如一台适用的铣床通过配备西门子公司的CNC 840D新一代控制器,使一家知名的透平机制造厂家获得成功,将这种符合需要的装备超出最初的期望投入了使用。
When older machines cease to serve, the first thing people usually think of is buying a new piece of equipment, ignoring the potential for modernization. For example, a modified milling machine for machining turbine blades, described below, shows that modernization of machine tools is possible and achievable. Turbine blade milling is a more complex process, which is clamped in a dedicated fixture by a skilled mechanic using existing techniques. A suitable milling machine was commissioned by a well-known turbine manufacturer with a new generation of CNC 840D from Siemens.
