One of the specialty machining processes available at Protomatic is our carbon dioxide coolant. In many applications, the typical "flood coolant" is sufficient. However, in applications requiring high cleanliness, or high-performance machining such as medical implant parts, carbon dioxide coolant is a great alternative. The Co2 is contained in a gas/liquid tank at 750-800 PSI and is assisted with filtered, dried shop air at 120 PSI. The combination produces a cool high-pressure directional coolant that produces improved lubrication and chip extraction at the cutting edge.
