VALONA GR 7005 has been specially developed for honing (with stone anD diamond tools) and superfinishing on ferrous and non-ferrous metals : hard, very high strength steels, extra soft and mild steels, etc. The oil is also suitable for cutting soft metals and aluminium. VALONA GR 7005 is a highly fluid, lubricating and detergent oil. It can be used for effective washing of honing stones and the surface of the workpiece; metal and abrasive particles settle out practically instantaneously, thus avoiding recycling in the spray circuit.
