本文提出了一种新的概念，以加强传统的组合加工“车磨”的长行程珩磨工艺精加工轴对称零件的孔。当摩擦学高应力零件的表面完整性至关重要时，珩磨是最佳选择。所提出的方法减少了所需的整体加工时间相比，传统的加工顺序在单独的机床，也提高了生产精度，通过一个单一的夹紧设置。阐述了组合加工中心珩磨加工的刀具设计、进给策略和可能的工艺链等基本细节。分析了两种不同工艺链的实验结果：第一，“车削-磨削-珩磨”（TGH链），其中珩磨是在磨削过程之后进行的;第二，“车削-珩磨”（TH链），其中珩磨是在粗车削之后直接应用的。实验结果表明，应用位置控制进给策略的开发长行程珩磨工艺的生产效率方面的有前途的结果。
This paper presents a novel concept to enhance the conventional combination machining ‘turning and grinding’ by a long-stroke honing process for finishing bores of axisymetric parts. Honing is the best choice when the surface integrity of tribologically highly-stressed parts is of vital importance. The presented approach reduces the required overall machining time when compared with that of the conventional machining sequence on separate machine tools, and also enhances the production accuracy through a single clamping setup. The fundamental details like tool design, infeed strategies and possible process-chains of the developed approach for honing on a combination machining center are explained. Experimental results of two different process-chains are analyzed: Firstly, the ‘turning-grinding-honing’ (TGH-chain), where honing is conducted after the grinding process; and secondly, the ‘turning-honing’ (TH-chain), where honing is applied directly after the rough turning. The experiments showed promising results for the applied position-controlled infeed strategy of the developed long-stroke honing process regarding the production efficiency.
