ADNOC slideway oils based on paraffinic mineral oils containing anti-oxidant, anti-corrosion, load-carrying, adhesive and copper-protection additives. These oils have been tested on a Staticinemetre friction-testing machine, a rig designed to evaluate the lubricating properties of lubricants used for machine-tool slideway systems. They showed no indication of stick-slip at loads of 1.5 bar and 3.0 bar at a sliding velocity of 2mm/ sec on V and flat slideway surfaces. ADNOC slideway oils have also been tested in a modified Cincinnati Milacron thermal stability test with steel and copper test rods in the presence of water. Evaluation of the test rods to Cincinnati color corrosion standards shows the excellent protection given by the oils under these severe test conditions (24 hours at 100 oC).
