TECH BRIEF productionmachining.com :: 29 :: Castrol's new metalcutting fluids can remain effective for longer than conventional machining fluids because of their resistance to changes in pH caused by microbiological breakdown. Cutting Fluid Specifications Castrol's Hysol XBB is a family of soluble or semi-synthetic cutting fluids formulated to help protect machine tools and produce a high quality finish when machining ferrous alloys. The fluid maintains system performance and fluid life, neutralizing as much as 24 percent more acidic material than standard cutting fluids (based on titrating seven fluids until a pH of 8.5 is reached), according to the company. This reduces, and can even eliminate, the need for biocide additives and overall fluid top-up volumes. According to a Castrol customer, switching from a standard cutting fluid, Hysol SL 35 XBB saved them 45 percent in overall fluid top-ups. Maintaining pH levels and controlling the growth of bacteria minimizes the propensity for corrosion or rust staining on finished components. Also, Hysol SL 35 XBB's wetting properties help keep machines and parts clean. Alusol XBB is a family of soluble cutting fluids designed to improve precision performance in aluminum machining. Fine aluminum chips can build up at the cutting edge, causing component quality issues from the first cut. The fluids combine Castrol's non-stick additives with its new metalworking fluids technology, acting in tandem to reduce aluminum build-up at the tool and to neutralize up to 33 percent more acidic material than standard aluminum cutting fluids (based on titrating nine fluids until a pH of 8.5 is reached). Using this fluid can reduce or eliminate the need for biocide additives. Based on the experiences of four customers switching from standard aluminum cutting fluids, this cutting fluid formulation can save as much as 30 percent in overall fluid top-ups. Alusol SL 51 XBB maintains a high surface quality for precision cutting, minimizing the need to rework or scrap output that has to be rejected. It, too, has excellent wetting properties to help keep machines clean and helps the cutting edges stay free from buildup, the company says.
