Vasco 7000 marks a step-change in titanium machining

The new vegetable ester oil-based, micro emulsion, Vasco 7000 from Blaser Swisslube, is an extremely high performance metalcutting fluid, specifically targeting what are seen as difficult-to-machine materials, including titanium and nickel-based alloys. Its composition excludes the use of Chlorine, Boron, Formaldehyde and Zinc, making it safe for operators, components and machine tools. During customer trials, says Alan Dalton Technical Director, Jemtech (UK), the UK importer of Blaser Swisslube products: "Vasco 7000 has been benchmarked against competing metalworking fluids, which are also reputed to be market leaders and the Blaser product has consistently outperformed in terms of increased tool life, longer sump life, reduced fluid cost and in generating significant reductions in overall manufacturing costs, Customers are experiencing a doubling of tool life, while taking advantage of increased cutting data, in some cases by as much as 65 per cent." From a financial perspective, Vasco 7000 also reduces the amount of topping up required in order to maintain the correct cutting fluid strength. Users are seeing significant reductions in fluid use, with top ups being done at 1 per cent concentrations, compared to the more typical 4 per cent. This makes Vasco 7000 highly economical to use and also reduces any environmental impact, as fluid waste is greatly reduced. Vasco 7000's economic credentials are further enhanced by the fact that it can be used in varying concentrations, with the optimum being between 5 and 8 per cent on the refractometer. Of particular interest to those machining components for the aerospace industry is the excellent rinsing behaviour of Vasco 7000. This ensures that components and machine tools are relatively clean after use, and reduces the quality concerns relating to components that become streaked from residual cutting fluids. Aerospace applications often go hand-in-hand with high performance, high pressure coolant, machining applications and here Vasco 7000 exhibits extremely low foaming behaviour, leading to a very stable machining process and reduced downtime.
