Abstract
A method for lubricating a metal workpiece during a metalworking process includes delivering supercritical carbon dioxide to the workpiece during the metalworking process. The supercritical carbon dioxide acts as a lubricant, coolant, chip evacuator, and/or carrier for another lubricant or corrosion inhibitor.
Claims12
A system for applying supercritical carbon dioxide for lubricating a metal workpiece for a metalworking process, the system comprising:
- a source of carbon dioxide;
- a pressure booster in fluid communication with the source of carbon dioxide;
- a high-pressure vessel in fluid communication with the pressure booster;
- a source of lubricant in fluid communication with the high-pressure vessel;
- a nozzle in fluid communication with the high pressure vessel;
- and
- a metal workpiece configured to be lubricated by applying supercritical carbon dioxide thereto during a metalworking process.
