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.

Of 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. From a financial perspective it also reduces the amount of topping up required to maintain the correct cutting fluid strength. In high performance, high pressure coolant, machining applications Vasco 7000 exhibit 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 Steve Coull, Managing Director, Jemtech (UK). “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.”

Vasco 7000’s economy is 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. Depending on the application top up rates for Vasco 7000 are typically under 1 per cent ensuring that running costs for Vasco 7000 are minimalised.
