Blaser Swisslube’s expertise in creating vegetable-based metalworking fluids has led to a breakthrough in the machining of titanium, particularly in aerospace applications where stable, and safe working environments are paramount.

The new vegetable ester oil-based, micro emulsion, Vasco 7000 from Blaser Swisslube is an extremely high performance metal cutting 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 “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,” says Alan Dalton Technical Director, Jemtech (UK), the UK importer of Blaser Swisslube products. “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 of 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 with reduced downtime.

“Blaser’s experience in developing and applying ester-based cutting fluids is second to none,” says Alan Dalton. “We are finding Vasco 7000 to perform extremely well under the most difficult of machining applications and surface tolerance requirements. These applications, by their nature, are traditionally time consuming with reduced feed rates and surface speeds, by changing to Vasco 7000 these limits are increased, which in turn adds profit directly into the component.  When you add this to the fact that it contains no bactericides, so has extremely good human/skin compatibility and the low running costs, we can see it becoming a very popular product within our range.”
