Should we continue with classic machining and coolant lubricants, or do dry machining and minimum quantity lubrication (MQL) represent viable alternatives? From a technology point of view, it is important to consider material properties and machine performance, but plant costs, energy and health aspects increasingly need to be included in any assessment of the overall process. Lubrication system manufacturers and scientists commented on these aspects in the first of this two-part series. Part 2 now looks at various machining technologies from the practical perspective of tool and machine manufacturers: a preview of EMO Hannover 2019.

Production managers in manufacturing often have to ask themselves: should we continue with conventional machining and coolant lubricants, or do dry machining or minimum quantity lubrication (MQL) represent viable alternatives? Several factors influence this decision. In Part 1 of this two-part series of technical articles being published in the run-up to EMO Hannover 2019, lubrication system experts and scientists give their assessment. Tool and machine manufacturers shed light on the subject in the second part.
