通常，研磨流体从喷嘴供应到研磨点。然而，难以向孔的深磨削点供应足够的冷却剂。因此，我们提出了一种替代冷却系统，其通过加工中心的供应系统从利用主轴的砂轮的内侧供应磨削液。在这项研究中，一种新的工具，小，深孔的磨削液供应，在这种方式。然后在各种磨削条件下加工0.45%C钢圆筒的内部。磨削冷却液从砂轮内侧供给，在各种条件下都能获得较高的形状精度和表面粗糙度。此外，该系统还可防止加工表面上的撕裂和砂轮上的负载。
Generally, grinding fluid is supplied from a nozzle to a grinding point. However, it is difficult to supply sufficient coolant to the deep grinding point of a hole. Therefore, we have proposed an alternative coolant system that supplies grinding fluid from the inner side of the grinding wheel utilizing the spindle through the supply system of the machining center. In this study, a new tool for small and deep holes was developed to supply grinding fluid in this way. The inside of a 0.45%C steel cylinder was then machined under various grinding conditions. Higher form accuracy and surface roughness were obtained under all conditions by supplying grinding coolant from the inner side of the grinding wheel. In addition, the system prevented tears on the machined surface and loading on the grinding wheel.
