Trials were initially set up for three products: a local boron amine technology coolant, a leading aerospace competitor coolant and HOCUT® 3450. The latter two products were both high ester EP type products with a very high level of lubricity. A total of 6 milling tools were monitored for tool change frequency during the period of the trial.

After a plant survey of machine tools, processes, materials and water conditions, HOCUT® 795 B was proposed supported by independent performance data on similar operations from other aerospace components manufacturers.

HOCUT® 795 B was proposed for machining trials supported by independent performance data on similar operations from other aerospace component manufacturers. HOCUT® 795 B has consistently shown itself to be the best in class coolant for aerospace alloys.

Quaker Houghton proposed HOCUT® 795 B, dedicated to Aerospace parts machining and well established for its long sump life and good stability. The customer began a trial with HOCUT® 795 B on a Mega 5 (MAG) milling tool machine. After 2 years HOCUT® 795 B was still in use, and there has been no sump clean-out and no anti-foam nor bactericide addition.

The company needed to make improvements in their machining oper¬ations. They were losing an average of one hour of productivity for each roughing cycle (4 hours lost machining time/ 24 hours). There were also issues with corrosion on machine tool beds with seals and coatings breaking down.
