Technology

Carbon Nano-Onions.

Carbon Nano-Onions (CNOs) are spherical, multi-layered carbon structures with a heat resistance of 1,700 °C. They were originally not developed for industrial applications, but were used in medical research – for wound care, biocompatible coatings and as drug delivery systems.

WHAT THEY ARE
  • Size: 7 nm primary particles, approx. 200 nm clusters
  • Material: 100% pure carbon
  • Structure: Multi-layered spherical shells
  • State: Stably incorporated into the emulsion or oil
  • Reactivity: Chemically inert, insoluble
WHAT THEY DO

In the cutting zone between tool and workpiece, Carbon Nano-Onions behave like microscopic ball bearings. They convert sliding friction into rolling friction – the decisive mechanism for controlling heat, wear and tool life.

This effect is not achieved through coating or chemical reaction, but purely mechanically – and therefore independently of material, geometry or cutting speed.

Safety & Classification

From a toxicological perspective, particle size is not the decisive factor, but rather chemical composition, reactivity and bioavailability. Carbon Nano-Onions meet all relevant criteria in an uncritical manner:

Chemically inert and non-toxic
Insoluble and non-reactive
Stably incorporated into the emulsion or oil
Non-volatile and not bioavailable
No migration into the air
No absorption through the skin or mucous membranes

Nanoparticles are part of everyday life — when grinding coffee, in road traffic and in candle soot. The difference with Nano-Onions: their properties are known, controlled and deliberately usable.
