HOCUT® 8640 performs exceptionally well for Aerospace Components Manufacturer

An Aerospace Components Manufacturer was milling 15-5PH Stainless Steel using a Niigata SPN 40 Horizontal Machining Center.  Milling a part with extremely hard material and complex geometry contributed to a high fluid and labor spend when using a competitor’s high-end vegetable-based coolant.  It required high concentrations and maintenance (frequent coolant make-up, high additive usage), and its poor sump life led to frequent cleanouts and recharges.  Trialing a popular semi-synthetic coolant addressed the maintenance and sump life issues, but  it required even higher concentrations, and more detrimental tool life suffered.The customer’s desirable outcome was to have a coolant that could provide at least original tool life without sacrificing sump life (6-month minimum) and operator acceptability (clean, minimal odor, minimal maintenance) was needed.The Houghton ApproachHoughton recommended HOCUT® 8640, an advanced soluble coolant designed for heavy duty machining, grinding and honing applications for a wide range of ferrous and aluminum alloys, especially harder stainless and high-nickel alloy steels.Results and BenefitsThe customer’s expectations have been exceeded. HOCUT® 8640 addressed the customer’s coolant requirements performing exceptionally well in terms of lubricity and chip removal; along with lowered usage, waste, labor, and downtime, and with more consistent concentration control.  The greatest benefit has been the elimination of additives; not only are they costly and labor-intensive, but also indicative of inconsistent coolant chemistry that can lead to additional parts inspection, as well as staining and rework.Other additional benefits HOCUT® 8640 provided:· Tool life stabilized.  Able to run the same number of parts per tool as with original vegetable-based coolant.· Coolant usage reduction.  Reduced required coolant concentration from 10-15% to 9-12%.  Little coolant drag-out led to reduction in makeup, great reduction in waste and associated cost and labor, and better concentration control.· Sump life improvement and operator acceptability.  Coolant runs clean, splits out tramp oil, keeps machine tool clean and free of scum, residue, and odor.  Sump life expected to exceed the minimum 6-month requirement.· Eliminated costly coolant additives and associated time/labor; previously required pH booster, defoamer, water hardeners, biocide, and fungicide.· Multi-metal compatibility.  Able to run other materials (Titanium, Renee, Inconel) on the same machine tools without the need for coolant or concentration changes.  Full shop conversion potential to improve inventory control.
