Technical principle: A revolution in extremely low-temperature processing
Liquid nitrogen low-temperature cutting uses liquid nitrogen at -196℃ to change the traditional cutting thermodynamic state, mainly in two ways:
Direct cooling : Liquid nitrogen is sprayed into the cutting zone, and experiments have shown that the surface roughness of stainless steel machined surfaces can reach Ra25μm
Indirect cooling : Through the internal cooling system of the tool, Lincoln University in the United States has confirmed that it can extend the tool life by 10 times
The core advantage lies in:
Zero pollution : Liquid nitrogen volatilizes to nitrogen, no waste liquid residue
High efficiency : Inhibits tool softening and breaks the "high-temperature wear" cycle
Versatility : Particularly suitable for difficult-to-machine materials such as titanium alloys
Industry applications: From cutting-edge to popular
A win-win situation for the economy and environmental protection
Cost comparison : Total cost for five years is 27% lower than conventional cutting fluid, and annual maintenance costs are 88% lower
Environmental advantage : Completely eliminate cutting fluid contamination, compliant with strict EU REACH and other standards
Policy support : China 's 14th Five-Year Plan explicitly encourages green manufacturing technologies
