Study tests electrostatic lubricant delivery for precision grinding
A study published in Lubricants tested electrostatic minimum quantity lubrication on GCr15 steel using a vegetable-based oil supplied at 100 mL/h. At +8 kV, the researchers reported 58.52% lower tangential grinding force and 30.58% lower surface roughness than conventional minimum quantity lubrication under the same experimental conditions.
LS interpretation: lubricant delivery and droplet behaviour deserve attention alongside formulation when evaluating machining performance. These are results from a specific laboratory setup, not demonstrated production-line savings or a general performance guarantee; transfer to other materials and machines requires validation.
