In the high-stakes world of automotive manufacturing, producing complex components isn’t just a challenge—it’s a mandate. From transmission housings with internal cavities to turbocharger wheels and structural parts made of hardened steel or aluminum alloys, today's automotive parts demand tight tolerances, clean finishes, and repeatable performance across thousands—if not millions—of units.
But traditional coolant systems often fall short when facing these challenges. Complex geometries make it difficult for conventional fluids to reach and cool critical tool-workpiece interfaces. Heat builds up, tools wear out prematurely, and secondary operations like deburring or cleaning become unavoidable. In high-volume production environments, these inefficiencies lead to downtime, rework, and mounting costs.
Fusion’s Pure-Cut® supercritical CO₂ coolant system changes the game. Designed for tight-tolerance machining and high-output environments, it empowers manufacturers to machine intricate parts at high speed—with confidence.
Whether you're machining multi-step bores, deep pockets, or internal channels, complexity creates friction—literally. Friction at the cutting edge causes heat. That heat can dull tools, warp parts, and slow cycle times. In traditional flood or MQL (Minimum Quantity Lubrication) systems, coolant often can’t penetrate deep cavities or precision features. Worse still, oil and water-based fluids cling to parts and chips, making post-machining cleanup an additional burden.
Now add challenging materials into the mix. Components like gear housings, control arms, or drive shafts are often made from heat-treated steels, cast iron, or difficult-to-machine alloys, all of which accelerate tool wear. And when you're running thousands of these parts on a production line, even small inefficiencies compound into major delays and added costs.
The industry needs a better way to maintain precision, manage heat, and hit production goals—all while reducing coolant waste and operator exposure.
Fusion’s Pure-Cut® supercritical CO₂ coolant system addresses the unique difficulties of machining complex automotive parts. By delivering supercritical CO₂ (scCO₂) directly to the cutting zone—through the spindle or nozzle—it provides highly efficient, targeted cooling and lubrication even in the most confined geometries.
Supercritical CO₂ behaves like both a gas and liquid, allowing it to flow into tight spaces, cool instantly, and carry away heat and chips at the source. Add a precisely dosed lubricant (with Pure-Cut®+), and you get oil-like friction reduction—without the residue.
The result? A machining environment that stays cooler, cleaner, and more controlled—even in the most demanding applications.
