The quality of machined components depends heavily on the accurate feed and accurate positioning provided by machine tool slideways with slideway oils playing an important role. Slideway oils must provide a stable, adhesive lubricating film in the presence of metalworking fluids even in micro-feed situations and when pressures are high. Good lubrication eliminates chattering and thus ripples on the surface of components caused by stick-slip.
RENEP CGLP oils were developed together with the Tribological Laboratory at the University of Darmstadt and the Laboratory for Tribology and Sliding Technologies (SKC-Technik). Carefully selected base oils and matched additives guarantee almost friction free movement at the lubrication points. Special attention during development was also paid to compatibility with the water-miscible cutting fluids used in machine tools. Anti-corrosion agents and ageing (oxidation) inhibitors are effective at relatively low temperatures (working temperature = room temperature). EP and anti-wear additives guarantee long machine life and exceptionally good operational reliability.
The selected additive combinations create layers which have a low internal friction. Furthermore, polar surface active substances form a stable, adhesive lubricating film. This reduces friction when movement starts, lowers the initial current consumption and optimises the efficiency of the machine tool.
