The Mobil Vactra Oil Numbered Series are premium-quality lubricants specifically designed to fully meet the requirements for accuracy and parts finish of today’s high production machine tools. They are formulated from high-quality base stocks and performance balanced with a progressive additive system that provides low frictional properties, excellent corrosion protection and foam resistance. A unique advanced additive package helps reduce stick-slip and chatter under thin film, boundary lubrication conditions. This allows smooth, uniform motion at design travel speeds. The Mobil Vactra Oil Numbered Series have been optimised to provide excellent separability from aqueous coolants in coolant systems while minimising the corrosive effects of high pH coolants on lubricated surfaces. The base stocks and additive package have been carefully selected to protect slides and ways while still providing good filterability. This is important because reduced flow or plugged applicator filters will increase stick-slip, chatter and wear. The metal-wetting and adhesive agents form uniform films that resist squeezing from way surfaces while the machine is not in operation.
