Description

Castrol Hyspin™ HVI 46 D (previously called Vario HDX) is a high performance machine tool lubricant, developed to

conform to the HLP-D (detergent) classification for hydraulic fluids.

Application

Castrol Hyspin HVI 46 D also incorporates lubricity additives to give smooth slideway motion on the combined hydraulic

and slideway lubrication systems of some grinding and gear cutting machine tools. Castrol HLP-D fluids contain

detergency additives which maintain dirt and oil oxidation products in suspension, preventing them from settling out and

forming deposits which could impair the free operation of valves, leading to erratic system operation. Machine tool

manufacturer's are increasingly specifying HLP-D fluids such as Hyspin HVI 46 D, having recognised their advantages

in increased system reliability.

Advantages

HLP-D fluid containing detergency additive.

Very high viscosity index.

Contains lubricity additives.

Maintains cleanliness and give reliable hydraulic action in fine tolerance systems.

Suitable for a wide range of hydraulic applications and giving consistent operation over wide temperature ranges.

Overcomes stick/slip, giving judder-free operation of machine tool slideways.
