在微加工中，主轴的跳动误差、重新夹紧误差和刀具处理等关键参数通常会对微刀具的寿命产生负面影响。为了避免这种负面影响，制造技术和生产系统研究所开发了一种新的机床——纳米研磨中心。纳米研磨中心是一款完全集成的工具生产和应用机器，用于微型铅笔研磨工具，无需重新装夹。制造具有定制刀具形状的超小刀具直径（< 5 μm）需要个性化的微型制造工艺，并进一步实现台式机床的模块化。因此，为了制造微型铅笔研磨工具，龙门式台式机床由三个模块组成：研磨模块、用于工具优化的μEDM模块、用于工具涂层的电镀模块。为工具应用提供一个纳米级定位 XY 工作台，并通过摄像头模块进行过程观察。该机床的独立模块安装在床身上，因此刀具主轴包括Z轴的移动必须接近每个模块才能制造或使用刀具。在本文中，将概述具有所有模块和功能的纳米研磨中心的概念。
In micro machining, critical parameters such as run-out error of the spindle, re-clamping errors and tool handling in general, have a negative impact on the micro tooĺs life. To avoid this negative impact a new machine tool - the Nano Grinding Center - has been developed at the Institute for Manufacturing Technology and Production Systems. The Nano Grinding Center is a fully integrated tool production and application machine for micro pencil grinding tools without re-clamping. The manufacturing of ultra-small tool diameters (< 5 μm) with customized tool shapes requires an individualization of the micro manufacturing process and further a modularity of the desktop sized machine tool. Therefore, the gantry type desktop machine consists of three modules in order to manufacture micro pencil grinding tools: The grinding module, the μEDM module for tool optimization, the electroplating module for tool coating. One nanometer-level positioning XY-table is provided for the tool application and a camera module allows the process observation. The independent modules of this machine are mounted on the machine bed, thus the traverse including the Z-axis with the tool spindle has to approach each module for tool manufacturing or application. In this article, the concept of the Nano Grinding Center with all modules and functions will be outlined.
