AEROSPACE LUBRICANTS


Elevating efficiency and quality in aerospace manufacturing


Michael Kosalko, Director of Product Development, Quaker Houghton Metalworking


The aerospace industry demands the highest levels of quality throughout its supply chain. For manufacturers creating critical components, this means having a focus on delivering to exacting standards, approvals, and regulatory requirements. To achieve this, elevating every aspect of production to its highest potential is essential to delivering consistently.


Michael Kosalko, Director of Product Development for Quaker Houghton, explores how effective fluid selection can enhance performance, quality, and consistency across various machining applications by providing greater stability and versatility.


Improving stability


It is crucial that machine operators know the importance of metalworking fluids, ensuring there are not only sufficient volumes for the operations being run but also that they’re optimised for those operations. Getting this make-up right will ultimately allow for smoother operations, improving efficiency through prolonged sump life and a reduction in the required volume of metalworking fluids.


The expected lifetime of a system sump can vary


depending on its size and the operations being performed. To maintain a consistent concentration of soluble metalworking coolant fluid, water additions compensate for evaporation and coolant concentrate makes up for losses due to carry out. This control is often accomplished with a diluted pre-mix emulsion whose composition can vary depending on the product. Designing coolants that have low carry out rates and are resistant to other means of additive depletion offers manufacturers advantages in both efficiency and cost.
