Trade Talks – High Pressure Coolant Systems and What You Need to Know.
High-pressure coolant (HPC) systems are a powerful upgrade for CNC machining and turning centers, delivering coolant at 500–2,000+ PSI directly to the cutting zone.
The result: longer tool life, improved chip evacuation, better surface finish, faster cycle times, and greater process reliability.
During metal cutting, friction generates intense heat. As water-based coolant approaches 100°C, it begins to boil, creating a vapor barrier between the tool and workpiece. This steam layer limits cooling and lubrication right where it’s needed most. High-pressure coolant penetrates this barrier, delivering coolant directly to the chip-tool interface for maximum effectiveness.
