Hocut 4940 is a semi-synthetic advanced metalworking fluid designed for machining tough alloys in the most complex metal removal operations, providing high lubricity without the use of chlorinated additives. It is low-foaming with high detergency, so it runs clean. It delivers high lubricity at low usage rates and provides high corrosion protection for both components and the machine tools. Pratt & Whitney approved Hocut 4940 for contact with gas turbine engine parts made from a variety of aerospace alloys including aluminium, steel, stainless steel, nickel-based alloys, single-crystal nickel alloys, cobalt-based alloys, magnesium, titanium, and titanium based alloys.
“Hocut 4940 is truly a global formulation enabling aerospace companies to achieve a step-change in productivity while incorporating new environmental requirements,” says Lee Bowditch, Houghton sales director. “It is especially valuable for aerospace companies with significant international operations because it conforms to health and environmental regulations including TSCA, REACH, DSL, METI, and PRTR. This enables a single product to be supplied locally to global operations.”
In addition to being chlorine-free, Hocut 4940 does not contain formaldehyde releasers, boron, TEA, DCHA or any other secondary amines. This makes it one of the most environmentally responsible fluids available to the aerospace industry.
Hocut 4940 is also said to provide performance advantages for metalcutting, including increased tool life, longer sump life, higher productivity, improved quality of surface finish, and reduced cycle time, all contributing to the lowest total cost of operation.
