Supercritical CO2 Cooling Technology

Leading Ultrasonic Machining Technology | Conprofe

The innovative Supercritical CO2 Cooling System adopts a unique system design to convert the low-pressure CO2 air recovered and purified from petrochemical, steel, food and other industrial production into supercritical CO2 fluid and turn it into -78°C low-temperature cooling medium for efficient cooling and lubrication of cutting tools.

Output control system and nozzles specially designed to ensure continuous and precise injection of supercritical CO2 fluid into the cutting area at room temperature.

Longer tool life and higher machining efficiency achieved with the mixture of CO2 fine particles and CO2 air constantly sweeping the cutting area to maintain clean and dry machining area and rapid cooling.

Unlike conventional low-temperature cooling media, supercritical CO2 fluids can be delivered at room temperature to achieve low-temperature cutting without complicated insulation measures.

●Work step
Low-temperature CO2 air source——Supercritical CO2 Cooling System——Special nozzles for Supercritical CO2 Cooling System——Machine tool——Nozzle layout——Workpiece machining

Coaxial piping design — coaxial casing pipes used to convey high-pressure supercritical CO2 fluid and lead low-pressure auxiliary airflow to minimize heat loss of supercritical fluid, thus ensuring its performance

Multi-channel nozzle design — avoid condensation, frosting and clogging at the nozzle outlet area to achieve uniform output and precise injection of supercritical CO2

Flexible output and control — multiple nozzles with independent on/off contorl can be equipped and directed at different directions;

CNC machine tool control allowed — can be controlled via CNC I/O interface control to realizes cutting process stop-and-go;

MQL technology integrated — MQL fluid can be mixed into supercritical CO2 fluid for better lubrication for special machining needs;

Easy set-up — the system functions with CO2 air source and auxiliary air source connected the system and special nozzles mounted onto the spindle; no need for machine tool retrofit.
