Transform your machining operations with the Pure-Cut® solution

Innovative Machining Solutions 

Fusion Coolant Systems

Our patented Pure-Cut® machining solution uses supercritical carbon dioxide (scCO2) to elevate your operations, providing many advantages over machining with conventional coolants and lubricants. Pure-Cut® is a non-toxic, non-flammable, and environmentally friendly solution that does not produce harmful waste. The scCO2 penetrates the cutting edge providing better cooling and lubrication, reducing tool wear and improving machining accuracy.  Parts are virtually burr-free with exceptional surface finishes. In addition, scCO2 is an exceptional solvent, leaving parts super clean, eliminating post-machining cleaning operations.

Extending tool life in CNC machining

Extending the life of tools for CNC machining is an ongoing challenge for manufacturers. A dull or broken tool slows production and adds cost to the product. Pure-Cut® solutions using supercritical carbon dioxide was shown to extend tool life by 2X over emulsion when cutting Ti-64.


Get premium prices for your machining chips

Machining metal produces chips, tons of them. These chips are valuable to a company when they can be recycled. However, dirty, wet chips have a lower value than clean, dry chips. The Pure-Cut® solution using supercritical carbon dioxide produces a naturally clean chip that doesn't require post-processing. Get the maximum value for your scrap with Pure-Cut® from Fusion Coolant Systems.

Preventing fires in CNC machining

Machining metal is an important part of the manufacturing process, and CNC machines perform that task efficiently and safely, but they are also a leading cause of fires in manufacturing facilities.  Many of these fires are caused by the oil-based lubrication systems used to cool the tooling in the machines. Supercritical carbon dioxide used in the Pure-Cut solution acts as both a fire suppressant and a lubricant in your machining process. Learn more here.
