In precision machining, cutting oil has long been the go-to solution for reducing friction and dissipating heat at the tool–workpiece interface. But as manufacturing evolves, so must the tools we use. Traditional oil-based coolants are messy, hazardous, and costly to manage—and they limit the efficiency of today’s high-performance CNC operations.
Fusion Coolant’s Pure-Cut® system offers a powerful alternative: supercritical CO₂ (scCO₂) that cools and lubricates with unmatched precision—without the drawbacks of cutting oil.
The Challenges of Traditional Cutting Oil
Oil-based coolants are still widely used in CNC machining, but their disadvantages are becoming harder to ignore. As operations scale up and environmental regulations tighten, the need for cleaner, faster, and safer solutions is clear.
- Environmental Concerns
Disposing of cutting oil is expensive and highly regulated. Improper handling can lead to serious environmental damage—contaminating soil and groundwater with toxic residues. - Operator Health & Safety
Exposure to oil mist increases risks for respiratory problems and skin irritation. Slippery floors and poor air quality create unnecessary workplace hazards. - Tool and Part Performance
Oil can hinder chip evacuation in tight geometries and may even degrade part surface finishes due to heat retention. It also contributes to burr formation and requires additional cleaning steps post-machining. - High Maintenance Costs
Oil-based systems require constant monitoring and filtering. Bacterial growth, fluid degradation, and disposal protocols all add to your overhead.
Pure-Cut®: The Modern Alternative to Cutting Oil
Pure-Cut® replaces cutting oil with a dry, clean, and more effective alternative: supercritical CO₂. This next-generation CNC coolant system transforms how shops manage heat, lubrication, and part quality.
- Superior Cooling and Lubrication
Supercritical CO₂ flows into confined geometries and cools instantly at the tool tip. A small dose of lubricant (in Pure-Cut+) enhances friction reduction—without residue. - Cleaner Machining Environment
scCO₂ evaporates on contact, so there’s no fluid to clean up and no mist to manage. Parts come off the machine dry, reducing secondary cleaning or washing. - Sustainable Manufacturing
Utilizing recycled CO₂, Pure-Cut® minimizes environmental impact and aligns with green manufacturing initiatives. - Worker Safety & Visibility
Operators benefit from a cleaner, healthier workspace with better visibility, less exposure, and no slippery surfaces.
Real-World Impact: Why Manufacturers Are Switching
Across industries, manufacturers who switch to Pure-Cut® from traditional cutting oil report major gains in productivity, safety, and cost savings.
- Longer Tool Life
By maintaining consistent temperature and chip evacuation, scCO₂ keeps tools sharper for longer. In many applications, tool life doubles—or more. - Faster Cycle Times
With better cooling at the point of cut, machines can run at higher speeds without overheating or part distortion. - No Coolant Mess
There’s no fluid collection, filtration, or disposal needed. That means faster turnaround between jobs and fewer maintenance interruptions. - Compliance & ROI
Pure-Cut® helps operations meet environmental and safety standards, while also improving part quality and reducing operating costs.
The Future of Machining Is Dry, Clean, and Sustainable
Cutting oil was once a machining essential—but it’s no longer the best option. With Pure-Cut®, Fusion Coolant is changing what’s possible in modern CNC operations: better performance, lower cost, and zero coolant mess.
Whether you're producing thousands of parts per week or machining ultra-precise components under tight tolerances, Pure-Cut® delivers the control and confidence you need—without compromise.
