A cutting fluid

is essentially used

for four reasons 

TO MAKE 1 AND 3 WORK EFFICIENTLY :

THE LUBRICANT HAS TO PENETRATE BETWEEN THE CHIP AND THE TOOL.

The cutting fluid must have an exceptional wetting power to do this : penetration at the interface by capillary action.

Tool wear results from very severe mechanical loads,
aggravated by heat, at the tool-part and tool-chip interface.

Congestion of emulsion molecules does not allow for sufficient penetration
between the tool-chip interface.

Congest ion of micro-emulsion molecules is less, but penetration
is still insufficient in the tool-chip
interface.

The infinitely small molecular congestion with ETERNA® 3000 allows for complete penetration between the tool and the chip. This is the nanolubricating principle.

ETERNA® 3000

PENETRATES THE TOOL INTERFACE
Capillary penetration is related to the surface tension of the fluid and the congestion of particles containing the active molecules.

ETERNA® 3000

Reacts strongly with the machined surfaces

The ETERNA® 3000 active molecules convey water to the interface.
(low congestion, low surface tension)

The evaporation of water entails highly efficient cooling.

- Simultaneously, the ETERNA® 3000 molecules react and are vigorously adsorbed by the machined surfaces. In this manner, they considerably reduce the friction coefficient.

- Furthermore, ETERNA® 3000 molecules perfectly protect surfaces against corrosion.
