显微机械加工中心使多道工序一体化

加工小零件会出现操作上的困难。「仅仅是这些零件的传输就常常造成损伤,工具的校准也是一个挑战。这就是我们开发多功能显微机械加工中心的原因,」Mikrotools(新加坡;www.mikrotools.com)公司的生产总监Alex Koo说道。

在欧洲,一种显微机械制造中心正用于加工医疗设备中的微型可植入产品、电子和感光纤维部件。

DT系列的CNC中心可进行车削、铣磨、微线放电研磨和微电子放电加工,精确度达到±1μm。为进一步提高精确度,可增加一个测量设备,使机器控制器能补偿工具磨损引起的误差。此外,另一个新颖之处是机器可制造电极,与其配合使用可使工件具有新的功能。

据Koo透露,目前 Med-tech的研究人员正用这种机器制造神经感受器和生理传感连接器。它也可用于制造生物可吸收缝线。

控制器可作为独立的产品使用,Koo补充道:「一些公司愿意自己制造设备,但是,如果不具备专业技术就很难设计微型控制器。」公司的MC-10四轴运动控制器可扩展到16轴。开放式结构使其易于整合到显微机械加工工具中。还有微型EDM发电机可供选择。

公司最近还开发了一系列台式车床。「我们注意到许多加工极小配件的公司使用的是这些庞大的机器。微型UPL系列车床具有20x20mm的工作空间,是为加工微米大小的部件而专门设计,」Koo解释道。令光学和生物医学领域用户特别感兴趣的是,UPL-2020车床可一次性加工完成,减少了可能的差错。目前,四台机器正用于新加坡大学的研究工作。至发稿时尚未投入商业应用。
