In this study, effects of minimum quantity lubrication (MQL) conditions on machinability were investigated in milling operations, which is an important machining method. In this context, nano-sized solid lubricant MoS₂ was mixed into MQL and EN-GSJ 700-02 spherical graphite cast iron was milled. Surface roughness and tool wear were examined and effects of nano-MoS₂ were investigated. A range of statistical analyses such as Dunnet test was performed to determine Ra results and their relationship with experimental parameters. Positive results were obtained from nano MoS₂ that was added to improve lubrication and cooling properties into fluid in MQL system. Lowest Ra value was measured as 0.47 µm in conditions of 5 bar pressure, 160 ml / min flow rate and MQL + 0.5% MoS₂ spraying. A 45% improvement was achieved in these conditions. Added nano MoS₂ played an alternative role on surface roughness and tool wear.

纳米MoS2在EN-GSJ 700-02最小量润滑（MQL）铸铁铣削中的实验研究

在这项研究中，研究了铣削加工中最小量润滑（MQL）条件对可切削性的影响，这是一种重要的加工方法。在这种情况下，将纳米级固体润滑剂MoS ₂混合到MQL中，然后研磨EN-GSJ 700-02球形石墨铸铁。检查了表面粗糙度和工具磨损，并研究了纳米MoS _2的影响。进行了一系列统计分析，例如Dunnet检验，以确定Ra结果及其与实验参数的关系。纳米MoS ₂获得了积极的结果添加该元素是为了改善MQL系统中流体的润滑和冷却性能。在5 bar压力，160 ml / min流速和MQL + 0.5％MoS ₂喷涂条件下，最低Ra值为0.47 µm 。在这些条件下实现了45％的改善。添加的纳米MoS ₂在表面粗糙度和工具磨损方面起到了替代作用。
