There is a better way

Cutting fluids are commonly used to reduce temperature and friction in metal cutting processes. These cutting fluids constitute a serious environmental hazard and health risk for employees, leading to a significant direct and indirect cost to all stakeholders. Industry has been looking for ways to mitigate the negative impact of the cutting fluids – and ideally to find a replacement for metal cutting fluids. Finally, the better way is here: Aurion.

Our Mission

Aurion transforms the global machine tools market by replacing metal working fluids and setting a new global standard for sustainable machining.


Cooled, Ionized air flow

Aurion system uses cooled and ionized air as a coolant and lubricant in the cutting zone.

Aurion is implemented using a dedicated air-cooling unit with built-in electronics and integrated software.

Aurion can be applied to both existing and new machine tools.

The system has no mechanical wear parts – leading to ease of maintenance.


The cleanest solution

Aurion technology is developed through a 10 year dedicated R&D effort. The Aurion solution is now ready for market introduction following recent comprehensive validation runs by high quality third parties, including Universities and leading Industrial actors.
