HIGH-PERFORMANCE NEAR-DRY MACHINING AND ITS TRIBOLOGICAL BEHAVIOR

针对可大幅减少切削液用量、环境友好的高性能近干加工，对其摩擦学特性进行了详细研究。因此，在需要高润滑作用的流体的铝合金加工中，发现一些化学化合物如酯类、醇类和酸类具有优异的切削性能，共存的水可以改善性能。此外，在不锈钢的近干式加工中（不锈钢是一种难以切割的材料），酯和水基冷却剂的混合雾供应被证明可以有效地提供更高的切割性能。

Regarding high-performance near-dry machining which can considerably decrease the amount of cutting fluids and is therefore environmentally friendly, its tribological behavior was investigated in detail. As a result, in machining of aluminum alloys necessitating the high lubricating effects of fluids, it was found that some of such chemical compounds including oxygen as esters, alcohols and acids had the excellent cutting performance and that coexisting water could improve the performance. Further, in near-dry machining of a stainless steel which is one of difficult-to-cut materials, hybrid mist supply of an ester and a water-based coolant demonstrated to be effective in providing the higher cutting performance.
