The following actions are recommended to help maintain system integrity during extended shutdown periods.
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.

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.
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.
Trials were initially set up for three products: a local boron amine technology coolant, a leading aerospace compet-itor 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.
The company needed to make improvements in their machining operations. 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.
