RENEP CGLP 150

Description 

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 microfeed 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 optimizes the efficiency of the machine tool.

Application 

To reduce the power consumption during slideway start-ups and feed situations, special attention must be paid to the lubricant between the sliding elements. Important parameters for the selection of the most suitable slideway oil are the cutting fluid, the slideway materials and the geometry of the lubrication grooves. The lubrication intervals must be matched to the machining operation and the design of the machine. Apart from the classic cast-cast, steel-cast and steel-plastic slideway materials, there is an increasing trend towards linear guides in machine tools. The RENEP CGLP series of products are also recommended for these machine elements. Moreover, RENEP CGLP 68 can also be used as a hydraulic oil according to DIN 51 524-2, ISO 6743-4. This product can thus perform the functions of a lubricant and a hydraulic oil. The RENEP CGLP oils were developed with the relevant technical application requirements of slideway oils in mind. RENEP CGLP slideway oils were supplied to all leading machine tool and component manufacturers.
