Throughout the sometimes-contentious world of machining, the debate rages about whether to apply flood coolant or cut dry. As in many areas of machining, the choice is not easy and requires careful and informed consideration. To further complicate the decision, minimum-quantity lubrication (MQL) can be a successful compromise that provides an efficient and …

In some cases, it may be beneficial, from environmental and cost perspectives, to machine without coolant (dry machining). However, many applications require machining with coolant for tolerance, surface quality and machinability. If coolant is required, it should be optimized to maximize its true potential.

Zhao et al. [6] carried out TC4 alloy milling experiments under liquid nitrogen cooling and achieved a more optimized machined surface quality than using direct milling without cooling. They found that the residual compressive stress on the machined surface was higher and this process contributed to improving the surface quality.

you're fine to mill without coolant, in fact a lot of carbide work is best done without it - compressed air instead to cool and blow the chips away. For sure coolant has advantages, but don't let it stop you from milling. A squirt bottle is handy to have if you don't have flood - get some water soluble oil and mix a bottle up as required ...

The radiative cooling paints without ball-milling exhibited the lowest solar reflectivity in comparison with the paints with ball-milling. At the same time, the paint made from 16.1 μm-glass bubbles had a solar reflectivity of 86.2 %, higher than that of the paint made from 47.9 μm-glass bubbles, which had a solar reflectivity of only 75.8 %.

Milling without lubrication and cooling produces the heat at the milling zone and it increases with the RPM. Maximum heat generated is taken away by the chips and the remaining is dissipated in the tool [19, 20]. The flank face of the tool starts rubbing when it encounters a heated surface.
