Introduction Equipment Minimum Quantity Lubrication allows to reduce the machining cost while keeping the surface finish as good as possible. The comparison between MQL methods using different pulverizing devices and cutting fluids has already been done. The objective of this study is to highlight the influence of the alloys during MQL turning of AA2024T351 and AA7075-T6 aluminum alloys. The machinability indexes are the roughness, the chip thickness and the tool wear. Conventional VS Numerical Lathe The use of a numerical lathe has been demonstrated. It clearly generates more accurate results. The experiments had been perform using a numerical Lathe (MAZAK Nexus 100 II M). The pulverizing device (designed by Tecnolub) is made by a pressurized tank spouting a continuous flow rate. A Sc
