Supercritical CO₂ Is Revolutionizing The CNC Machining Space

Different from cryogenics or liquid nitrogen, supercritical carbon dioxide brings unprecedented sustainability and efficiency to CNC machining.

The Supercritical Difference

Decrease Cycle Time, Improve Cut Quality, and Extend Tool Life with supercritical CO₂

Supercritical CO2 inherently provides lubrication effects that match those of traditional cutting fluids. A simple solution for lubrication and cooling, supercritical CO2 is a fluid state of CO2 held above its critical temperature and critical pressure. At this point, the CO2 looks like a gas, but has the density of a liquid – providing powerful cooling and lubrication for machine tools with minimal integration challenges for your manufacturing facility. Supercritical CO2 can also carry and disperse chilled nanodroplets of oil for even more powerful lubrication.

Launch Supercritical CO₂ on New or Existing Machine Tool With Minimal Modifications

Pure-Cut® and Pure-Cut®+ were designed to use supercritical CO2 for cooling, lubrication, and advanced chip removal. Pure-Cut and Pure-Cut+ do not overhaul machine tools like cryogenic or liquid nitrogen coolants. Instead, they work with existing machine tools, delivering CO2 in it's supercritical state into the cutting process and providing advanced coolant and minimal quantity lubricant if needed.

Outperform Cryogenic or Liquid Nitrogen Solutions with Supercritical CO₂

  • Liquid Nitrogen: Compared to liquid nitrogen, Pure-Cut® and Pure-Cut®+ use supercritical CO2, a pressurized and heated CO2, which is 100% compatible with existing, through spindle machine tools.
  • Cryogenics: Compared to cryogenics, Pure-Cut® and Pure-Cut®+ use supercritical CO2 and require minimal machine modifications that can easily be changed to use other cooling and lubricants later.
